The design professional has the responsibility` to'coordinate' all construction documents and ensure co"mpatibilitybetween documents. • The report and design documents shalf be dated, signed and stamped by the design professional according to the plan submittal procedure. ; • For alternate methods of design requests, the applicant shall set performance criteria for his design. Performance criteria shall be reviewed, amended and approved by the Building Official prior to start of design. Alternative Design Revi wNerification ; . The Building,Offcial, has the,responsibilityto review design submittals for compliance to,the adopted codes and procedures. If the Building `Official does not have'the expertise on staff to make a thorough and competent review, the Building Official shall select a consultant that possesses the necessary qualifications to perform a third -party or peer review. Cost of peer review shall be paid by applicant to the Building Department prior to commencing the review. • Verify that all applicable information and justifications listed above as requirements.for submittals is received and verify that evaluation and design methods used by designer are appropriate to the alternative proposed.. • Verify products are being used. in accord ance'with, their, listing .conditions as required, by recognized listing agencies.

The Solution • Oif kfetW is a thermally efficient and environmentally responsible, non -toxic insulation, which is easily foamed into open or closed cavities in walls, roofs and ceilings. • At the time of application, its consistency is like shaving cream and after a few days, it hardens into a stable foam to maintain long-lasting, high insulation value. • Its basic raw material components are air, water, and MGO cement, which when combined, create a cost-effective, safe and high performance product. Developed over 25 years ago, air krete's efficacy is both time and test proven. • Many clients, including the Audubon Society realize the outstanding technical and environmental qualities of air kretee . The Audubon Society installed air kretee in their Headquarters in New York City, a building, according to its architect, Randolph Cmxton, that was designed to"create a model headquarters... to reduce both environmental and economic costs of buildings."

SAMPLE DESCRIPTION: Airkrete Wall Panel The 60"x60"x3.75" thick Airkrete Wall Panel was fabricated by Federal Conservation Group and provided to VTEC Laboratories Inc. ,for ASTM E 814/UL 1479 fire endurance testing;;# The wall was made up of 7 pieces of 2x4 studs, 4 pieces forming a 60"x60" square frame and the other 3 pieces were placed inside the frame spaced 16" O.C. One layer of 60"x60"x5/8" Type X gypsum boards was attached to each side of the frame using gypsum board screws. A 2"x4" junction box was located 34" high and 19" from the side. Conduit pipe ran from the top to the junction box and from the junction box to the bottom of the panel. A hole was cut in the gypsum board exposing the opening of the junction box. The junction box was left uncovered. A 2" pipe ran vertically through the frame, 21" from the side. It had a "T" Connection 21" high. A hole was cut in the gypsum board exposing the opening of the "T" connection. The cavity between the gypsum board was filled with Airkrete. The side opposite the opening of the junction box and "T" connection was exposed to the furnace.

ASTM E814/UL1479 PROCEDURE: The furnace used in this test measures 5ft x 5ft. The outside construction is steel and the furnace is lined with a ceramic refractory insulation. A single burner is centered vertically in the wall opposite the sample. This burner is rated for 1.5 million Btu/hr and is of the flat flame or non -impinging flame design. Furnace conditions are monitored by three Inconel- sheathed chromel-alumel thermocouples. These thermocouples are positioned 6" from the face of the sample. The sample was oriented vertically in the front opening of the furnace. The unexposed surface temperature of the sample was monitored by eight, 20 gauge type K, fiberglass sheathed thermocouples. An insulating pad was placed over each of the six thermocouples on the gypsum board. The fire test was run following the ASTM E814/UL 1479 `time - temperature curve. The hose stream test was performed using a 2-1/2 inch diameter hose and National Standard Playpipe equipped with a 1-1/8 inch discharge tip at distance of 20 ft from the sample. The hose stream test was performed after the fire test on the exposed side of the sample. The hose stream was applied to the sample for 24 seconds based on a 16 sq. ft exposed area. RATING CRITERIA: F Rating: Fire Test: The Fire stops shall not permit the passage of flame through the openings or allow any flaming on the unexposed side. Hose_ Stream Test: The fire stops shall not develop any openings that would permit projection of water beyond the unexposed side. 4 "TEC 9100.2862 REV. 1.0 FEDERAL CONSERVATION INC.

In that time, it has collected a small but very enthusiastic group of advocates, especially among the chemically sensitive. There are also skeptics, however, who are concerned about its long-term durability or just question whether it is worth the higher cost. Recent evidence about the product's firestopping capabilities may provide the big break air krete advocates have been waiting for. Air krete insulation is essentially foamed minerals: magnesium oxychloride cement, derived from sea water, and a particular variety of ceramic talc mined in Governor, New York. These minerals are mixed with a proprietary foaming agent -"glorified soap suds," according to air krete inventor R. Keene Christopher -and sprayed with pressurized air through a foaming gun. The resulting foam has a density of 2.25 Iblft3 (26 kg/m3). It takes a few hours to cure, so when it's being installed in open cavities a fine screen is stapled across the opening to hold the foam in place. Air krete used to be pink, but some purists objected to the use of red dye #2 food coloring, so d now has a blue-green tint, achieved with an inert mineral pigment. Air krete is quite effective as an insulation, with an R-value of 3.9 per inch (RSI-27/m). Like other foamed or blown -in insulation, it is much more effective than batts at filling cavities, especially odd -shaped or hard -to -reach spaces. Air krete is not flexible after it cures, however, nor does it bond to surfaces, so shrinkage or movement in a frame may open up small gaps. Air krete may be most notable for its performance as a firestop material. Although the company has long touted the fact that air krete will not create smoke or contribute to flame spread, its performance in a fire goes beyond these factors. Sea Cliff, New York architect Sergio Zori reports that a standard, 2x4-framed wall filled with air krete insulation has passed a 2-hour firestopping test. Anecdotal evidence seems to confirm this claim: One section of an old bam in Acworth, New Hampshire was converted to living space and insulated with air krete. A severe fire subsequently gutted the living space, but the rest of the barn was saved. The building's owner and local fire officials credit air krete in the walls separating the barn from the residence for the building's survival. Air krete has also been used to retrofit party walls with inadequate fire -stopping characteristics in some New York City apartments and has been unofficially credited with preventing a fire from spreading there as well, according to Zon. The two concerns most often raised about air krete are its friability and its apparent shrinkage. The cured material is undeniably friable, and it will turn into powder when rubbed, even lightly, by hand. This friability doesn't seem to be a problem in closed cavities, however, as we've seen samples several years old in perfect condition. In locations subject to extreme vibration, however, one may want to test the material before using it. The shrinkage issue is also unconfirmed, and independent tests conducted to meet state requirements in Minnesota measured no shrinkage at all. Gaps created by wood framing that has dried out are a likely cause of this perceived problem. Although many chemically sensitive individuals swear by air krete, healthy housing expert John Bower is not among them. Bower advocates the use of conventional insulation materials, such as fiberglass or cellulose, while sealing the wall cavities effectively so occupants are not exposed to anything that might be released by the insulation. "I don't have a problem with air krete," he says, "I just think there are better places to spend your money." As Bower notes, one of the objections to air krete is its relatively high cost. Prices vary by region and by the nature of the job, starting around $.30 per board foot ($1271M), installed cost. Labor is an important factor, because of the work involved in stapling the screen over the cavities. For projects on Long Island, Zori has found air krete to be just slightly more expensive than Icynene. He uses many different types of insulation on various projects and finds air krete the most comfortable in terms of on-the-job irritants. He feels that with the added benefit of firestop-ping, its worth the extra investment when possible, but he notes that for deep cavities in a roof or ceiling it becomes prohibitively expensive. Zori finds air krete especially effective as a retrofit insulation for uninsulated walls. He also recommends using it around bathtubs and Jacuzzis: 'SNe always try to spray around the tub when we have air krete on a job. It holds in the heat and dampens vibrations, creating a more solid feel for fiberglass tubs." Air krete literature also recommends the product for use in concrete blocks. While the material is likely to be compatible with the potentially damp conditions in the block, it may be hard to justify the cost in an application when most of the thermal resistance is short-circuited by the concrete. Air krete was developed and is patented by Air Krete, Inc., of Weedsport, New York, The company licenses manufacturers and installers, providing them with the proprietary ingredients.

TOOLS AND EQUIPMENT FOR CLEAN- 46 FOAMING HOUSE 46 UP 2 PART A —WOOD FRAME CONSTRUCTION I PLATFORM FRAMING • Construction form most common today. ck�fW • Each level constructed of 8 ft. long studs, usually 16" on center, set on plates and sub floors that are fire stops so that wall cavities run only the height of each floor. • If windows are 2 1/2' or higher above floor, open house immediately below windows for both first and second floors. • Open as necessary for access to cavities above windows and doors. • If windows are less than 2-1/2" above floor, open wall cavities half way up on each floor. • Open as necessary for access to cavities above and below windows and above doors. • See Part B —Siding Types for specific opening techniques. • After opening, probe all cavities to be sure that there are no obstructions. II. BALLOON FRAMING House • Common to older houses; developed in Mid -West in middle 19th century. Predecessor to platform framing. • 16 ft. long studs extending from sill to eaves. • Wall cavities run full height of wall unless obstructed by fire or draft stops at floor joists. This possibility must be check by probing. 3 • Wall cavities may be open into cellar. Possibility can be check by probing or visually from cellar if sills are exposed. • Access to wall cavities may be possible from attic particularly at gable end walls. • If wall cavities are open from attic foam second floor from there. • Open as necessary for access to cavities below second floor windows. • Foam first floor from outside. It windows are 2Yz' or more above floor, open immediately below windows. If windows are less than 2'/z' above floor, open half way up wall. • Open as necessary for access to cavities above and/or below windows, etc. • If second floor cavities not accessible from attic, foam from outside as in platform frame. • See Part B — Siding Types for specific opening techniques. After opening, probe all cavities to be sure that there are no obstructions. House • Modern Ranch. etc. • Usually balloon frame In which case gable ended wall cavities may open into space over ceiling. • Open as for first floor, balloon frame above. • See Part B — Siding Types for specific opening techniques. • After opening, probe all cavities to be sure there are no obstructions. N III. BRACED FRAMING ,a xl$l RE; IF 1 CL • Oldest method of frame construction in this country; brought over by early settlers. • Is a modification of post and beam construction? • You can usually find evidence of bracing, if the first floor joists, and sills are expose in the cellar. • You can usually find evidence of heavy corner posts on the interior by boxed in corners and by the main central support wall. • Bracing is 2 x 4's on diagonal with the broadside completely obstructing many or even all of the wall cavities. • Open each story just above floor level AND just enough below ceiling level to be sure of missing drop girt. • Also open half way up wall between windows and corners where knee braces are likely. • See Part B — Siding Types for specific opening techniques. Be ready to do a lot of probing. • Salesperson should give himself a price cushion on this job. ALTERNATE METHOD • Open house immediately below windows (windows will usually be well up from floor level.) • Probe EVERY cavity opened to determine where obstructions occur and open each 'blind' cavity individually. Also open as necessary over windows and doors 5 IV. RIBBON FRAMING Y • Horizontal nailers obstructing cavities. • This style enjoyed popularity in the 1920's and is usually found on an otherwise balloon frame building. • Still common in some areas of the country, particularly the South. • Often found if house has vertical board siding. • Interior wainscoting suggests the possibility of ribbon framing • Open house over nailer. Locate nailer by use of stud finder, or correlation with top of wainscot, etc. f Open as necessary above doors and above and/or below windows. • After opening probe to be sure there aren't additional rows of nailers above or below the first. • If siding is vertical open over every other stud. • See Part B — Siding Types for specific opening techniques. V. POST AND BEAM CONSTRUCTION • May be found in very old houses. • Conventional framing may be used between posts except that studs may be anywhere from 8" to 36" apart — in the same building. Verticals may have been determined by eye. • Identification of heavy corner posts by boxed in interior corners as with braced framing above. Also main support wall. • Also possibility of braced or X-framing. • Salesperson should give himself a price cushion on this also. 0 POST AND BEAM COMMERCIAL BUILDINGS • Construction can be heavy wooden members as shown or can be steel posts and beams. • Exterior surfacing often of corrugated metal siding and roofing. • May have concrete slab floor rather than joist and board floor. RESIDENTIAL • Determine form of framing used between posts and open accordingly. • Locate each stud individually. • After opening, probe every cavity for possible obstructions. i Make sure to open and foam all blind cavities. • See Part B — Siding Types for specific opening techniques. WOOD OR STEEL COMMERCIAL • Foam from inside. See Part G of this manual for specific technique. • NOTE: • When an old house has added additions over the years, each subsequent addition can be of a different construction method and require different prepping techniques. • Try to estimate the age of the house to help identify the construction method. • Try to determine if it was built professionally. Non-professional construction may not conform to standard form in many respects. (See Post and Beam construction for examples.) • Become familiar with local fire laws and their history as a guide for when to expect the use of fire stops, but do not count on any conformity. II PART B — SIDING TYPES: OPENING AND CLOSING TECHNIQUES IQW39 10007.11]Oki __91M f71 Lei Method #1 — Removal • Location of strips of siding to be removed depends on the framing method of the house. See Part A. Corners: • If corner board is used, or if corners lapped or bevel fit, run utility knife down joints to cut paint seal and avoid paint chipping. (If homeowner intends to repaint entire house after, less care needed about paint chipping.) • Where metal corner caps have been used, use utility knife to cut paint seal if necessary, to remove corner cap, see Part B, Section VI —Vinyl Siding. To remove clapboard: 1. Run utility knife to cut paint seal along top and bottom of clapboard. 2. Use nail pullers to pull nails in clapboard above one. 3. Use pry bar to loosen upper clapboard. 4. Use nail pullers to remove nails in clapboard. 5. Loosen corners of board with pry bar and remove. NOTE: Place first floor clapboards, painted face in, against base of wall immediately under section where it was removed. Place second floor clapboards away from house, keeping pieces in order. This will avoid mixing up the pieces and make replacing quicker and easier. 1. 1. Drill 2-9/16" hole through sheathing over the center of each cavity. F 2. For over or under window cavities inaccessible from the exposed strip of sheathing, a. For older windows drill a hole into the short stud bay through the window sash framing where the window normally seats. These holes can be plugged with 1 1/8" wooden plugs applying clear silicon and after foaming, closed the bottom sash. This is the preferred technique b. Drill 1 1/8" hole through siding (not recommended unless the only alternative.) 3. Foam all cavities To close: 1. Reverse steps of removal process to replace clapboards. 2. In renailing, set nails slightly above or to one side of original holes making sure nails go into studs. Use galvanized siding nails or plastic coated, anti -rust bedder nails in dented areas. 3. Run bead of caulk along knife cut when replacing clapboard. 4. Where holes are drilled through the clapboard, use proper size plugs to close. Drive plug in flush or countersink slightly. Caulk or exterior spackle cover and smooth area over plug. Using a 1'/2" putty knife and Method #2 — Non -removal 1. Direct drilling of holes through siding and sheathing into cavities. 2. For location of holes, refer to appropriate framing method in Part A of manual. 3. Drill 2-1/8" holes over center of each cavity. 4. Foam all cavities. 5. Drive plug in flush or countersink slightly. When plug is nearly flush, tap around edge of plug so that hammer is also striking siding. This will prevent driving the plug in too deeply. 6. Using a 3%2" spackling knife and American Hardware or Dap exterior spackle, cover and smooth the area. Do not work it; two or three swipes should be enough. In touch up painting, tail the paint out in both directions. This procedure completely hides any sign of the plugs. OTHER HORIZONTAL WOOD STRIP SIDINGS • Use Method #2 as above under clapboard OR • Remove siding for access to sheathing. See appropriate section of Part A for location of siding to be removed E and Rabbetted bevel 1. Loosen bottom edge of strip above one to be removed. 2. Pull nails on strip to be removed. 3. Use pry bar at corners to loosen board; remove and store as noted RAEaE7= under clapboard. SEVEL-3 4. Drill 21/8" hole through exposed sheathing over center of cavity. Fes. 7 _5. Foam all cavities. 6. Reverse procedure to replace siding. Board and Batten Wide Batten To remove: 1. Pull nails and remove wide battens as necessary. 2. Drill 2-1/8" hole through sheathing over center of each cavity. 3. Foam all cavities. 4. Caulk along edges of battens when replacing. Fig. 8 BOARD & BATTEN (WIDE) Narrow Batten To remove: 1. Loosen narrow batten above board to be removed. 2. Pull nails and remove narrow batten below board to be removed. 3. Pull nails holding board; remove board. 4. Drill 2-1/8" hole through sheathing over center of each cavity. 5. Foam all cavities. 6. Caulk along edges of both battens when replacing. 10 Fig. 9 BOARD & BATTEN (NARROW) Tongue and groove • Almost impossible to remove without damaging boards. Drill through as explained above under clapboard: method #2 — non -removal. • This also applies to tongue and groove applied vertically. Fig. 10 TONGUE & GROOVE 11 II VERTICAL WOOD SIDING BOARD AND BATTEN • Can be true board, in which case when wall is open check for possibility of ribbon bracing nailing strips. • More likely to be 4' x 8' plywood sheets. Wide Batten • Set nails through and remove batten over every other stud. • Make rectangular cut over stud to give access to cavities on either side of stud. Keep cut area inside width that is covered when batten is replaced. • Foam all cavities. • Replace batten. • Nail slightly to one side of original nail holes. Narrow Battens • Too narrow to cover access cuts. f Use one of three possible methods to foam. • Method #1: Drill four 1 -1/8" holes per cavity. Foam. Plug and caulk to close. • Method #2: Drill as for Method #2 under clapboard. Foam and close the same. • Method #3: Foam from the interior. • If siding is painted, drill and plug methods work well as evidence of plugs can be covered. • If siding is stained, very difficult to stain plugs to match. Explain to homeowner and give him option of having the work done from the inside. Fig. 12 VERTICAL BOARD & BATTEN NARROW BATTEN 12 True board and batten • Wide batten: proceed as for wide batten plywood, above. • Narrow batten: Choose board for removal either over center of each cavity OR over every other stud to allow access to adjacent cavities. To open: 1) Loosen narrow batten on one side of board. 2) Pull or set nails through batten on other side of board and remove batten. 3) Pull nails holding board and remove board. 4) If board removed is centered over stud, make rectangular cut over stud to allow foaming of two adjacent cavities. 5) If board removed is over center of cavity, check nailing pattern in sheathing as clue to whether or not framing uses ribbon nailers. Drill 2-1/8" holes as necessary to gain access to all cavities. Probe the cavity to double check. 6) Foam all cavities; replace boards and battens. REDWOOD • If a form of board and batten, use appropriate procedure above. • Usually 4' x 8' sheets with rough -sawn surface. Painted surface 1. Drill holes using method #1 or #2 as given above for narrow batten over plywood. 2. Caulk and texture over plugs to match siding. Naturally -aged or stained surface • Will be almost impossible to match plugs to siding well. • Explain to homeowner and give him the option of having the work done from the interior. SHEET )OD ROUGH 13 III. HARDBOARD LAP SIDING • Looks similar to clapboard but is heavier. • Can be finished to look like clapboard or shingles, etc. • Usually about 10" exposed to weather and is''/z" thick (10" exposed clapboard would be W thick). • Comes in 16 ft. long sheets and because of weight and brittleness, removal is a two -man job. • Do not drill through hardboard if you can possibly avoid it. Very likely to chip. Best always to remove siding and drill through sheathing. • Location of sheets of siding to be removed depends on the framing method of the house. See Part A. Surface -nailed hardboard Iap sidina Nail heads exposed To remove: 1. Run utility knife along top and bottom edges of piece of siding to be removed, paint chips off very easily on hardboard. 2. Do not use nail puller; instead slip pry bar or wonder bar well under edge of upper piece of siding. Do not put pressure on edge of piece or the hardboard may chip. 3. Pry board loose to pop nails enough to be removed. 4. Pry bottom edge of lower piece of siding with same care to pop nails. 5. Remove nails and lift off piece of siding. 6. For access over windows, etc., remove siding as necessary, do not drill through. Fig 24 HARDBOARD LAP SIDING SURFACE NAILED Alternate methods for removing hardboard siding: If nail heads are small, punch the nails through the siding instead of pulling them. Or slide hack saw blade up under edge of siding and cut off the nails. In replacing siding drill new nail holes slightly to one side of old ones. 1. Drill a 2-1/2" hole through sheathing over the center of each cavity. 14 2. Foam all cavities. To close: 1. Reverse above procedure to replace siding. 2. Use large headed, heavy shank spiral nails, not clapboard nails, as they won't hold the weight. 3. Make sure that nails bed into studding; the sheathing will not be enough to hold the weight. 4. Slide removed shingle under adjacent shingle for safe keeping. 5. Drill 2-1/8" hole over the center of each cavity. Be careful to place hole where it will not be exposed by gap between shingles when shingle is replaced. 6. Foam all cavities. To close: 1. Slide uncut shingle back up into place. 2. Re -nail through same holes using small -headed siding nails set at slight angle to original nails. If the shingle had to be cut, run a thin bead of caulk along cut edge. Replace and re -nail as above. Fig. 16 DOUBLE COURSE SHINGLES Single Course Shingles Nailed underneath lap; no exposed nails. To open: 1. If painted, run utility knife around edge of shingle to break paint seal. 2. Bevel cut exposed shingle off at lap. 3. Slide removed shingle under adjacent shingle for safe keeping. 4. Drill 2-1/2" hole over center of cavity being careful to place hole 15 where it will not be exposed by gap between shingles when shingle is replaced. 5. Foam all cavities. Fig. 17 SINGLE COURSE SHINGLES To close: 1. Run thin bead of caulk along cut edge of shingle. 2. Replace shingle and nail in place using two finishing nails. V. ASBESTOS CEMENT SHINGLES • Never drill through asbestos cement shingles, always remove. • Age of asbestos affects pliability so brittleness and cracking can be a problem. • Procedure depends on age and condition of shingles. • Choose shingle to be removed to expose sheathing over middle of cavity. • Hole placement depends on framing method used in construction -- see Part A of manual. Newer asbestos shingles in good condition • Shingles are 1' x 4' in size with four holes/4 nails showing along bottom edge of course. Usually is not nailed at top of course. • Asbestos in good condition will have a `spring' to it. 1. Use pair of large, heavy duty end nippers with as flat a head as possible. 2. Push in with nippers and grab the head of the nail. Pull nail if possible. Otherwise, snip off the head. 3. Remove or cut all 4 nails. Loosely replace one nail at one corner of the shingle. Using this nail as a pivot, 4. Allow the shingle to swing down out of the way and to expose the sheathing. 5. 1. Drill 2-1/8" hole through sheathing over center of each cavity. 16 6. Foam all cavities. To close: 1. Drive in the shanks of any cut nails. 2. Slide top edge of removed shingle back up under lower edge of upper shingle. 3. Re -nail at an angle slightly away from original nailing. Older asbestos shingles or shingles in poor condition Older shingles are 1' x 2' in size with 3 holes/3 nails along bottom edge of course. They may also have 2 holes/2 roofing nails along top edge of course which will be hidden under edge of upper shingle. Shingles in poor condition will be brittle and have no `spring' so that you will not be able to get a hold of the nail head with the end nippers. Damage to the shingles in removing is likely. Explain to homeowner and ask if he has any extra shingles which you can use if necessary, or see if you can buy any to match. And/or ask the homeowner if it would be possible to do the job through the interior wall. If you must go in from the exterior: To open: 1. Loosen the shingle above the one you need to remove. 2. Using pry bar, remove the roofing nails from the top of the shingle to be removed. 3. Using the end nippers, or if necessary the pry bar, remove the lower course of nails. 4. Loosely replace one nail at one corner of the shingle. Using this nail as a pivot, allow the shingle to swing down out of the way to expose the sheathing. 5. Drill and foam as newer asbestos shingle above. ' xuT�i� ' To close: ZrJ CZAER 1. Replace undamaged shingles as given in previous section. 2. Replace damaged shingles with new ones and proceed as above. 17 VI. ASPHALT COMPOSITION SIDING Never drill through asphalt, always remove. See appropriate section of Part A for location of siding to be removed depending on construction of house. Asphalt shiplap sheet siding • Sheets are 2' x 4' x 1/2" thick with an asphalt face on an insulation board back. • The usual pattern is imitation brick with a black mortar line. • Usually nailed on with about a dozen nails driven through the fake mortar line. • Must be careful of possibility of face chipping. If piece of face chips, immediately re -glue with face cement to avoid losing chip. • Good idea to ask the homeowner if he has any extra sheets which can be used in case of damage. To open: 1.

POTENTIAL PROBLEMS AROUND WINDOW AND DOOR OPENINGS IN OLDER HOUSES A common practice in older construction was that of first running the top and bottom window headers to the next regular studding and then framing in the sides of the windows within that span. See illustration below. Careful location of studding around windows and precautionary probing will prevent the possibility of overlooking these blind cavities. Trussing over window or door openings of 3' 6" or more in width was a recommended `gUR practice in balloon framing. L Suspect the presence of trussing when: • Cavities over windows seem to fill more quickly than they should. • In drilling a hole in the middle of a cavity above a window you unexpectedly hit a framing member. • In foaming over wide windows in an older house, take the precaution of probing. 25 PART D - MASONRY CONSTRUCTION I CONCRETE BLOCK CONSTRUCTION Core filling of existing building Salesman must find out depth of wall below ground level to add to estimate of foam needed for job. I. slightly to bind hose in hole. Use hammer action drill with carbide bit for drilling masonry. To open: 1. Drill one 11/8" hole in every block at ground level. 2. Make each succeeding row of holes 4' above the previous row. 3. Drill all holes before foaming to avoid having bits of masonry falling down into fresh foam. To foam: 1. Foam by horizontal rows beginning at ground level, and work up, row by row, to top of wall. 2. Stick application hose into hole and pull up 3. Foam will flow over interior block division and fill adjacent cores. 4. Foam until foam shows at hole above. (This takes about six seconds per hole in an 8" block.) To close: 1. Ream each hole with wire brush to remove all remnants of foam from block. 2. Using Sakrete and V-shaped mortarboard, push Sakrete into hole with pointed trowel. Trowel over. Core filling of new construction • Attach thin wall PVC pipe to application hose: Ny • If foaming 8" or 10" blocks use PVC pipe with a %" outside diameter and push PVC pipe a couple of inches up inside the application hose. • If foaming 12" blocks use PVC pipe with a 1" inside diameter and push end of application hose a couple of inches down inside the PVC pipe. • The length of the application hose should be as long as or longer than the length of the PVC pipe. However, keep the length of the PVC pipe/application hose combination as short as possible for ease of handling. • Make test foam to determine gram weight AFTER attaching the PVC pipe. • Adjust air pressure accordingly to propel the foam out of the pipe 1. Foam from above down EVERY core. PJ Drop PVC/application hose combination as far down the core cavity as possible. As the foam reaches the level of the end of the PVC, it will force the PVC pipe back up and out. 3. Foam cores under windows before sills are in place. Block cavity wall 1. Foaming should be done through the interior wall, if possible (see Part E — Foaming from the Interior). 2. If necessary to foam from the exterior, use over length drill to go entirely through the concrete block and into the stud cavity. Fig. 34 BLOCK W/CAVITY WALL BRICK CONSTRUCTION Brick -on -brick cavity wall • Usually a 1 '/" to 2" cavity between inner and outer brick walls. • Inside brick wall is usually plastered over for interior finish so must foam cavity through exterior wall. Use hammer action drill with carbide bit. 27 To open: To 1. First row of holes should be about 1', above downstairs floor level. 2WCK•o1v8Rrclf CAYITYWAZL 2. Drill a %" hole every 2'/2' horizontally. 3. Drill through the mortar at the conjunction of three bricks. 4. Repeat rows of holes at 2' intervals up the wall. Holes of each succeeding row should be staggered from the preceding one to form a triangular pattern. Foam: 1. Using an 8" length of tubing and a hose clamp, jury rig a reducer to fit inside the end of a standard application hose. 2. To check on filling: place pencils in all unfilled holes adjacent to the one being foamed. 3. When foam reaches pencils, they'll move. 4. Immediately stop and go on to the next hole. 5. Fill all holes in the bottom row first. Then keep working up by rows. To close 1. Ream each hole with wire brush to remove all remnants of foam from mortar. 2. Use Sakrete and V-shaped mortar board; push Sakrete into hole with pointed trowel. Trowel over. Alternate method for foaming Brick -on -brick cavitv wall 1. Remove a whole brick about halfway up the wall. 2. Probe the cavity to eliminate the possibility of studding. 3. If studding exists, remove one brick over center of each cavity. 4. If entire cavity between inner and outer brick walls is unobstructed except for metal ties, then remove one brick about every four feet horizontally. 5. For technique in removing and replacing bricks, see below under Method #1, Brick veneer on wood cavity wall. Brick veneer on wood cavity wall • Metal ties used every fourth course, 16" o.c. • Usually has 1" air space between brick and sheathing besides main cavity. Just do cavity. • If possible foam from interior. • If foam from outside, there are three alternate methods. Method #1 1. Locate studs from inside of wall and correlate to the outside. 2. Choose bricks over studs to gain access to two adjacent cavities for each brick removed. /"A/R .SPACE 3.

Using hammer action drill and W carbide bit, drill 4 holes per 8'high cavity. Place holes at the conjunction of three bricks. 2. Then extend holes through sheathing into the cavity. 3. Pressure fill all cavities with foam. 4. Fill all holes with mortar as in closing for brick -on -brick cavity wall above. Method #3 29 1. If there is a wood facer board at the top of the wall, it may be possible to drill 21/a" holes through the facer board to gain access to as many cavities as possible. 2. To foam under windows drill down through sills. 3. To reach cavities inaccessible by these means, use one of above two methods. NOTE: Brick walls other than the stretcher or running bond type shown above cannot be foamed. They will be solid or in a variety of complicated, obstructed cavity forms. Also, even with stretcher/running bond, be sure that it is not used as a veneer mortared directly to a concrete of tile wall; there will be no cavity in that case. III. STUCCO AND STONE VENEER SHEATHING V STUCCO Arz, J7/E4711IM6 ANello'?J OR TIES Fi' 3 52,0 ,5 YPIVFZR • Both can be found used as facing on concrete, concrete block, brick, or tile walls as well as on wood cavity wall construction. • Only the cavity wall construction can be foamed, and this should be foamed from the interior. Stucco Chips very easily and patching is rarely very successful. Commonly found on a variety of architectural styles including imitation half-timber Tudor, 'Spanish mission', etc. Stone Can be solid wall instead of veneer. Removing stones from a wall is likely to result in damage either to wall, the individual stone, or both. 30 PART E - FOAMING FROM THE INTERIOR I EXISTING BUILDINGS Requires a certain amount of ingenuity to leave as few traces of access holes as possible. • Potential approaches: Access through mopboards — generous 6" to 8" high baseboards in older houses. 1. Balloon frame: fill both first and second story walls from second floor mopboard providing no obstructing fire or draft stops. 2. Platform frame, obstructed balloon frame, or braced frame: fill second story walls from upstairs mopboard, first story walls from downstairs mopboards. 3. Areas inaccessible from mopboards, like around windows, etc., drill down through sills or use over length drill to go up through headers. Access from cellars and attics. 1. Possibility of attics in balloon frame giving access to wall cavities. 2. If roof is steep enough to give sufficient maneuvering room, may be able to take a right angle drill with an extension and drill down through the top plate into exterior wall cavities. Use two 1 1/8" holes per cavity. 3. Balloon frame: wall cavities may be accessible from cellar. If draft stop used at floor level, drill up through. 4. Platform frame: may be able to drill up through sole plate from cellar. Use two 1 -1/8" holes cavity. Watch out for nails. Solutions requiring special cooperation of homeowner. 1. Kitchens: go in through walls in backs of cupboards. 2. Bathrooms: remove sections of tiles; Marlite walls; go in through base of wall and cover holes by adding a new rubber baseboard. (http://www.marlite.com/tech-details.aspx) 3. Other rooms: go in through the top of interior wall if homeowner is willing to invest in a new molding to cover the work. Of if homeowner is willing to add a chair rail to his walls, go in at that height. NOTE: Use carbide hole saw for plaster. 31 II NEW CONSTRUCTION • In New construction, use 4-Mil Poly Film Vapor Barrier. • Apply vapor barriers on the side of the insulation toward the heated space. There are six methods for foaming wall cavities in new construction. The first three are open cavity methods; the second three are closed cavity methods. Open Cavity Cover all open cavities with tightly stretched netting. Closed 1) After the netting, fill each cavity with foam. If voids left during foaming, let the foam set about 20 minutes; then give it a shot of foam. Bulging of netting occurs with this technique. When applying netting try to make it taut enough to keep bulging to no more than %" to minimize crushing when dry wall is applied. 2) If dry wall is already in place, but the exterior siding is not yet on, work from outside. Drill 2- 9/16" holes through exterior within 6" off the top of the cavity. Drop the hose to the bottom of the cavity then pull back 1" to 2". Begin fill count to 8 slowly and withdraw the hose while the cavity is being filled. 3) If exterior siding is in place and dry wall is up but not finished off, use hole saw to drill 2 9/16" holes through dry wall over center of each cavity. Cover holes with tape after foaming. The contractor will attend to the rest of the finishing. NOTE: Closed cavity methods are pressure filling and result in minimal shrinkage. Infiltration spaces around windows and doors Since these spaces are usually narrower than the diameter of the application hose, the process of filling them can be messy and wasteful. To avoid this: Using scrap plywood at the job site, make a V-shaped container about 3' long with a ''/z" opening at the narrow end of the V. Tie the ends of the V together with scrap wood. (See figure 40.) 2. Place the narrow opening of the V against the infiltration space and run the application hose down the opening to funnel the foam into the space. 3. Move the container along the length necessary to foam fill the entire space. 32 III. FLOORS OVER CRAWL SPACES • This applies to both new and existing construction. • The following method also applies to floors over unheated cellars and unheated garages under heated living spaces. INSULATING OVER CRAWL SPACE 1. Gain access to the crawl space. 2. Based on the thickness of foam needed to attain the desired R value, staple Netting or Tyvak to the sides of the joists the necessary distance below the floor boards (Fig. 41). 3. Make a 1 1/2"to 2" slit in the Tyvak or apply the application hose to the netting and foam. 4. Go back and spot fill any voids left during the foaming process. 5. After the cavity is foamed make additional slits in the Tyvak for "breathing" NOTE: Ideally, 6 Mil Poly Film should be put down on the ground of crawl spaces and fastened to the foundation walls to act as a moisture barrier. Make sure crawl spaces are well vented. 1. With vapor barrier: 1 sq. ft. net free vent area per 1500 sq. ft. of crawl space area with at least 2 vents, one in each foundation wall. 2. Without vapor barrier: 1 sq. ft. net free vent area per 150 sq. ft. of crawl space area with a minimum of 4 vents, one near each corner of the crawl space. 33 PART F - ATTICS AND CEILINGS I ROOF TYPES The following figures illustrate the basic types of roofs, and installation of insulation. The numbers within circles indicate the various types of wall, floor, and ceiling constructions encountered. For instructions on how to foam each particular type, refer to the appropriate number in section III. The term attic is any space between the ceiling joists and the roof rafters. This space may be almost big enough for a basketball court, or it may be just high enough for a man to squirm through on his belly. The case of an unfinished attic of reasonable size and with windows, it's a good idea for the salesman to ask the homeowners if they intend to finish the attic as living space at some later. It can make a difference as to where the insulation should go. Gable roof Fig. 42 .`& " FINISHED A77.X WIXNEP WALU$ ex UNGS GABLE ROOF Fig 43 S CEILINC GABLE I The degree of slope can vary considerably so that there may be a full- sized attic with adequate headroom and may or may not be finished as living space (fig. 42), or the over ceiling area may be so low that there is only a few inches clearance between the ceiling joists and the base of the ridge rafter (fig. 43). 34 Dormers sometimes used in addition to the basic gable roof form (fig. 44). The shed roof dormer illustrated in figure 44 is common in one -and -a -half story houses. Two other common dormer forms appear in figures 48 and 49. Fig. 44 Fig. 45 FINISHED ATTIC W/KNEE WALLS & CEILINGDOLIBLE GABLE ROOF There are also multiple gable constructions. Figure 45 illustrates one of these, the full double gable. In this and in other multiple gable roofs, the common use of knee walls creates small blind attics at corners where two slopes come together. Do not overlook the need for insulation between the joists in the floors of these tiny attics. Cathedral A Y. -lu �+ut�.ssvc.a This is actually a form of a gable roof. The distinction that makes it a cathedral ceiling is the steepness of the roof slope and the fact that the entire area under the roof is part of the conditioned living space. This means that the ceiling is carried as the interior finish on the base of the rafters so that the only place for the insulation is between the rafters. A common use of cathedral ceilings is in A -frame construction. 35 �r UMIAUJIMOAMC ��..� �v �rr'r/n UNNOVT FLOOR • The degree of slope can vary so that there can be anything from a full-sized attic with adequate headroom to only a few inches of clearance. • With the addition of dormers, hip roofed attics can be finished as living space, in which case watch out for blind attics in corners. • The under -roof area finished as living space is usually finished as living space. • Usually the exterior of dormer side walls are finished with the same material as the rest of the roof, often shingles. • Sometimes knee walls will also be present. • The finished ceiling may be carried all the way to the ridge rafter instead of allowing the small ceiling cavity shown in figure 48. • The ceiling is often carried on the base of the rafters as in the finished attic shown in figure 49. However, ceiling joists may have been used to create a shallow attic above. uvxivrswcnti . �FTNIS1vcD Sometimes instead of the upper roof aNrrc ; /y arrrc being flat as shown in the illustration, it w17'rFt04R<INRNSARDROOF will have a shallow hip construction. Fig. #9 WrTH DORAIMS • A notable example of the mansard roof can be found in the classic Victorian house. 36 Shed roof and Flat roof • These two roof types differ from the others in that they do not have a ridge. • In both types the ceiling can either be carried on the base of the roof rafters as shown in the illustrations, figures 50 and 51, or ceiling joists may have been used to create a cavity between the ceiling level and the roof. Fig. 50 NO ATTIC SHED ROOF J.y. u. ring ML".r II VENTILATION All attics and ceilings ventilation should be above the insulation to prevent moisture build-up and condensation problems during the heating, season and to prevent heat build-up in the living space in the summer. • Use the largest possible vent that will satisfy both practical and esthetic considerations. • Install vents before foam application. • Vent openings must be protected against the entrance of rain and snow. • Ventilation pathways must not be blocked by insulation. Determine the minimum total net free ventilating area required for the attic/ceiling space. 37 1. Net free area is the opening through which air can pass unobstructed. All protective coverings effectively reduce the venting surface so that vent size must be increased to offset the obstruction. 2. Ceilings WITHOUT vapor barriers require 1 sq. ft. of net free vent area for each 150 sq. ft. of ceiling area. 3. Ceilings WITH vapor barriers require 1 sq. ft. of net free vent area for each 300 sq. ft. of ceiling area. 4. Whenever possible use a combination of ridge/gable vents and eave vents to achieve maximum cross ventilation. Van -pitch vents and continuous soffit vents can be adapted to most venting situations. It is essential to vitalized sidewalls of the exteriors in the Northern Climates. This is accomplished by drilling and applying three aluminum 3/8" Thimble Vents equally spaced per stud bay from the primary 2 9/16" application hole. This prevents moisture build up behind oil -based paints, felt/tar paper under siding, non-perferated Aluminum foil, polyethylene films or any of the potential vapor barriers on the cold side. Gable roof • �/4 total vent area at each gable end (gable vent) �/4 at each eave (continuous soffit or cornice vents). • OR '/2 total at each gable end. • Blind attics, particularly ones isolated in corners, should also be vented independently of the gables. Do not forget venting on dormers. Cathedral • '/2 total vent area at ridge (ridge -line louver), '% at each eave (continuous soffit or cornice vent). • OR'/2 vent area at each eave (continuous soffit or cornice vent). • OR if slope of roof is too steep to accept a ridge -line louver, construct a ceiling as shown in figure 52 to form a • ventilating attic.

Mansard roof • If ceiling is at roof there is no really good solution to the venting situation, unless you install a roof line louver in each cavity, and cost would be prohibitive. • If there is a ceiling cavity, use a roof ventilator and cornice or continuous soffit vents on all eaves. Gambrel roof • 1/2 total vent area at each gable if ceiling cavity exists, or ridge vent if no ceiling cavity, 1/2 at each eave (continuous soffit or cornice vents). Don't forget venting on dormers. Shed or Flat roof • Use'/2 vent area at each eave) continuous soffit or cornice vent). • On a sloped or flat ceiling where you have only the depth of the rafters to foam in, ideally you should create ventilation pathways between the eaves and the ridge or ceiling cavities in order to provide ventilation for summer heat build-up To create the ventilation pathway, staple backer board panels 1" in from the exterior or roof side of the rafters (figure 53). Foam between that and the interior ceiling surface. Where it is impossible to get in to construct this ventilation pathway, you should not foam insulate this unless the homeowner understands that there may be an odor problem and wants it foamed anyway. It is a good idea to have this understanding and agreement in writing, and signed, if at all possible. INSTALLING BACKERBOARD FOR VENTILATION PATHWAYS In situations where 2x4 lumber has been used for rafters and it is impossible to make ventilation pathways, there is little point in installing vents on cathedral, shed, or flat ceilings/roofs. If the 39 lumber used is 2x6 or larger, install vents as required; shrinkage on upper surface of foam will help offset the lack of constructed ventilation pathways. III METHODS FOR FOAMING General precautions In working in attics, particularly unfinished ones, it is a good idea to wear a facemask. In addition, essential in most attic applications is a good trouble light. Where there is no normal access to the attic, you can go in up through the ceiling over a closet, or if adding gable vents, use the rough cut of the vent opening for access. In finished attics with knee walls, use adjacent closet walls, if available, for access to blind attics. 3. The depth of foam used will depend on several factors: 1) the recommended R value for the winter design condition for the particular locality; 2) the space available for foaming, (obviously when foaming between roof rafters, the depth of the rafters is the limiting factor); and 3) whether or not there is already some insulation in place. 4. It is a good idea to install rafter vents under any roof deck. On the bottom side use tyvak or netting 5. If the ceiling already has foil -backed Fiberglas insulation, you can foam directly over it, but do NOT put down poly because the foil is a moisture barrier. If any other insulation, including Fiberglas without the foil back, is already there, you should remove it, and then put down tyvak, and foam. 6. Do not foam directly on top of a dropped ceiling to avoid weight problems. If there is an older ceiling above the dropped one, foam that and make sure you apply the exterior wall insulation up to that height. If there is no older ceiling (you may find this in commercial buildings particularly), you cannot insulate unless the owner agrees to constructing a ceiling above the dropped ceiling. Where foaming an attic without a floor or of adequate headroom, make sure that the homeowner understands that it cannot be used for storage unless the foam is protected against compression and other mechanical damage. The following numbers refer to the numbered circles used on the illustrations under section I. Roof Types. 1: Unfinished attic, no floor, reasonable amount of headroom. After following the appropriate guidelines and precautions above, apply foam between joists. 2: Unfinished attic with floor. Access is probably provided for and the space used for storage. Remove strips of floor boards at 8' intervals across attic for access to all between -joist spaces. After checking the ceiling construction below, and taking the proper precautions, apply foam between joists. 3: Unfinished attic/ceiling cavity, no floor, minimal headroom. Proceed as Type 1. The problem will be the lack of headroom. If clearance is so low that it's impossible for a man to get in, refer to Type 9 below. M Floor/ceiling in blind attics behind knee walls. These may be either isolated corners as in figure 45, or run the full length of the eave area as in figures 42, 44, and 45. Here again the problem is the lack of space in which to maneuver. Otherwise the procedure is the same as for Type 1. 5: Knee walls. These should be done from the back while you're in the space behind them doing the floor/ ceiling cavities under Type 4. The backs of the knee walls will probably be open; staple on backer board or tyvak to close them before foaming. Do NOT use poly film or you create a vapor barrier where one should not be. A Dormer side and face walls. Usually fill from the exterior at the same time as the walls of the house. If necessary, do them through the interior wall inside the attic. In figure 44 the dormer face wall is an extension of the knee wall below. If the cavities are not obstructed where the lower roof meets the dormer wall, you may be able to foam the upper and lower sections of the wall at the same time. If the cavities are open, make sure that you will not be filling the entire blind attic with foam. 7: Between rafters accessible from small attic/ceiling cavities. Ideally, these areas have a ventilation pathway using backer board as discussed under Ventilation in Section II. If these rafter areas have a relatively short run between the ceiling 41 cavity and a knee wall blind attic, and if the size lumber used for the rafters is 2x6 or more in depth, you may be able to install the backer board by working from both ends of the cavity providing the ends are not blocked off. Install the backer board before doing ANY foaming in the attic. Foam these cavities before foaming the ceiling cavity, and check beforehand to be sure that you will not be pumping the foam out the bottom of the cavity and filling up the blind attic below. [A Cathedral ceiling - between rafters. 1. Foam from the exterior: 2. Choose shingle located over the center of each rafter cavity. 3. Remove shingle, drill 2 9/16"" hole through roofing boards over the center of each cavity, and foam. 4. Use wood plug to close. 5. To seal against leaks coat wood plugs with Silicone or Latex. 6. Replace shingle. If the roof is aluminum or slate, foam from the inside through the interior surface. Go in high on the slope of the ceiling and patch or plug access holes. 4 Ceiling cavity with only a few inches of clearance between ceiling joists and ridge rafter. In this case the cavity is too small for a man to get into, yet the cavity is big enough that it would be expensive and impractical to ROORNG 604R� py ROOf/NG SN/NGL6S .NP/completely fill with foam. OOF/,Btlg RIDGE RAFT64, RAFTER The only solution to foaming this is very .POOFIv6 R6MOyw expensive. ss TO 6XP036 CE/LING CEILING ow ry -q�^ F:g ay ROOF ,SECTION LOW scoFE ROOF To gain access to the cavity it's necessary to open up a 2' or so wide section to one side of the ridge and running the entire length of the roof. Remove all roofing '/LING material in this strip to expose the cavity ✓,o/sr for foaming. See figure 54. Foam as in Type 1. Replace all roofing layers and make water tight against leaks. 42 IV NEW CONSTRUCTION • Always install netting or Tyvak between the foam and the interior surfacing material. • Must work in cooperation with the construction crew so that they will understand how and when to the foam and will leave cavities open and accessible until after they are foamed. 1. Foam floors of blind attics while knee walls are still completely open. 2. Close backs of knee wall cavities with backer board, foam fill, then apply the netting or Tyvak. 3. Do sloped ceilings, such as cathedral, where foaming between rafters prior interior installation. First install backer board for ventilation pathways as discussed in Ventilation Section C. Then staple the Tyvek in place; make sure it is stretched tight. Add temporary furring strips as shown in figure 55 (below) to support Tyvek at center of cavity. Foam in from the top before stapling the Tyvek in place at the top of the cavity. When the foam has set, remove the furring strips. ROOF S.EOMON An alternate method is, after putting in the backer board and the netting, instead of adding the furring strips, the sheet rockers can install all but the top panel of sheetrock. Then foam the cavity from the top. See figure 56, above. 4. For a flat roof, or a low clearance situation as shown in figures 43 and 54, use the method given in #3 above or foam the ceiling joists from the top before the roof is sealed. 43 PART G-- POST AND BEAM COMMERCIAL BUILDINGS These can be either wood or steel framed, include Quonset, and pole buildings. • Buildings can have both wood or corrugated metal exterior walls and usually no cavity construction or interior wall. • Use Stick -clip method to create cavity for foaming. • Stick -clip method works on both ceilings and walls providing that surfaces are dry and warm at the time of installation, and that, if metal wall, the corrugations are not too narrow to take Stick -clips. • If use of building requires that the wall is to be protected against damage, then regular cavity wall should be constructed to the necessary height and Stick -clip method used above that. • Thickness of foam required depends on temperature the owner wants to maintain inside. • Job usually requires a three-man crew. Materials needed 1. Polyethylene sheeting: 4 mil thickness, comes in widths of 8% 12', 16', and greater in roll form. Width needed depends on distance between poles. 2. Stick -clips and washers: size needed depends on thickness of foam to be installed — 2'/z" Stick -clips for 3" of foam; 3'/" for 4" foam; 4-1/2" for 5" foam. 3. Mastic. 4. Good quality panel adhesive. 5. Staple gun and staples. Application of Stick -clips Ceilings: Use no Stick -clips if rafters are 16" o.c. If rafters are more than 16" o.c., number of rows of Stick - clips needed is the maximum spacing distance of 16" apart. For example, beam rafters 4' o.c. would need two rows of Stick -clips. Apply as given for walls in the next section. ME Walls: Spread bottom of base of Stick -clip with mastic. Set first row of Stick -clips vertically 12" from pole and spaced a maximum distance of 16" apart. (Refer to illustration below.) Make next row 12" to 16" over and offset from first row to form a triangular pattern. Allow mastic to dry at least 24 hours before foaming. Application of Tyvek Film CAVITIES FORMED BY S' M 1. Use width of Tyvek that completely spans distance between two poles. 2. Use panel adhesive to seal Tyvek to sides of each pole; the distance out from wall depends on thickness of foam to be applied. 3. Press Tyvek onto adhesive. 4. With wood pole construction, fold any extra edge of Tyvek over and staple to pole placing staples no more than 6" apart. 5. On steel pole construction, adhesive is only fastening and must be thoroughly dry before foaming. 6. Fasten Tyvek to floor either with adhesive (surface must be clean and dry for adhesive to hold) or with a nailing strip. 7. Fasten Tyvek to beam at top of wall or, if ceiling is also to be insulated, use a continuous run of sheeting for ceiling and wall to insulate and seal roofline. 8. Make Tyvek as taut as possible. 9. Press Tyvek onto the nails of the Stick -clips and put washers on to secure Tyvek. Foaming 1. Make vertical slit, 1 Y2' to 2" long, in Tyvek about 1'/2' over from pole and spaced 4' to 6' up. Make as few slits as necessary to foam each wall section. 2. Insert application hose in slit and pump full, letting plastic belly out. Do not try to work it with your hands. 3. Air pockets will develop and are hard to see from close-up. 4. Go back, fill these air pockets by puncturing Tyvek at those places, and pump in enough foam to fill the voids. 45 PART H - CHECKLIST FOR EQUIPMENT AND TOOLS TOOLS FOR PREPPING AND FOAMING HOUSE ABSOLUTELY NECESSARY SUGGESTED AS GOOD IDEA 1 Large toolbox 1 Asbestos siding cutter 2 One hammer per man 2 Two vinyl siding removers 3 Four nails sets 2 fine -tipped & 2 coarse tipped 3 Two pair nail pullers 4 Two pin punch sets 4 One hand saw 5 Two Wonder bars and/or flat bars 5 One extra heavy duty industrial drill 6 Two pair end nippers (horseshoe nippers) 7 Two utility knives and extra blades OPTIONAL 8 Two caulking guns 1 One circular saw 9 Two pair rubber gloves 2 Two %" carbide bits for brick 10 Three 50' extension cords 3 Two 1-1/8" carbide bits (for block) 11 Two putty knives One 1-1/2" wide & one 2-1/2" wide 4 One hammer action rotary drill for block and brick) 12 Trouble light and/or good flashlight 5 Two carbide hole saws (forplaster) 13 Two tape measures — 12' or longer 14 One plumber's snake and/or band iron 15 One reciprocating saw & extra blades 16 Three SHARP 2-1/8" bits, two SHARP 1- 1/8" bits & one 2-9/16" bit 17 Dusk mask (for attic) 18 One 6' stepladder 19 Two 18' (full) extension ladders 20 Two 30' (full) extension ladders 21 One 1-1/4" wide SHARP wood chisel 22 Window scraper 23 Nail and/or utility aprons 24 Clean rags TOOLS & EQUIPMENT FOR CLEANUP ABSOLUTELY NECESSARY_ OPTIONAL 1 Garbage bags 1 Lawn or shop vacuum 2 Leaf rake 3 Broom 4 Two 30 gallon Rubbermaid garbage cans 5 150' High quality garden hose w/ trigger shut-off.
