Air Sealing Existing Wall Cavities |
|
The Tiger Foam Slow Rise is especially suited to air sealing homes that were built without insulation/air sealant in the outside walls or as a soundproofing for common walls in condominiums, office and conference rooms, apartments, and to isolate family rooms, bathrooms, laundry rooms from excess noise. Tiger Foam Slow Rise foam insulation is also recommended for filling boat hulls, pontoons , and flotation devices or anywhere injected foam can be used.
Air Sealing Closed Wall Cavities
Many outside walls on older homes lack insulation/air sealant in the exterior walls. In a 2"x 4" wall you will get an R-24 and in a 2"x 6" wall, you will get an R-38. This may or may not be the right choice in a 2"x 6" wall if you are in Florida or Southern California, but if you are in Canada in the mountains, Shorelines, Plains, or anywhere it just plain gets cold!! This may be exactly what you need.
Calculating amount of spray foam required for outside walls:
1. Measure your outside walls length x height to get the gross square footage
2. Subtract the linear square footage of any doors or windows in that wall to get the net square footage
3. Use the net square footage and subtract 10% for the studs (which won't be sprayed)
4. Take that total and multiply it by 3.5" for a 2"x 4" wall or multiply by 5.5" for a 2"x 6" wall
5. The grand total provides the number of board feet required to complete the project
Example: You have a 10' long x 8' tall wall, one door measuring 3' x 7' and a window that is 3' x 3'
8' x 10' = 80 sq feet in outside walls
80 sq ft - 21 sq ft (3' x 7') - 9 sq ft (3' x 3') = 50 sq ft
50 sq ft x 90% = 45 sq ft OR 50 sq ft - (50 sq ft x 10%) = 45 sq ft
For 2” x 4” cavity: 45' x 3.5” = 157.5 board feet to insulate. For a 2” x 6” cavity: 45' x 5.5” = 247.5 board feet to insulate.
You will need one TF-200 SR kit for the 2” x 4” wall. You will need two TF-200 SR or one TF-600 SR for the 2” x 6” wall.
Note: that the SR kit is less expensive the more you buy quantity. A 600 bd ft kit is almost the same price as 2 of the TF-200s, so buying a large 600 kit is 30% free product over buying 2 of the 200 bd. ft. kits.

Technical Information
- Unless otherwise stated, the density of TIGER FOAM is 1.75 lbs. per cubic foot.
- Tiger Foam two component foams are rated at R-Value of 6.2-7.4 per inch (depends on the external factors such as humidity and temperature during the application and curing).
- The size of the kit, i.e. 600 or 200, is indicative of the board foot coverage or expanded yield for that kit. Thus, a 600 kit will cover 600 square feet at 1" thick. A board foot as it relates to this product is a square foot one inch thick. The kit size is yield of the kit expanded.
- The conversion to cubic foot yield for these kits is generally 600 yields 50 cubic feet and 200 yields 16 cubic feet of foam.
- To convert gallons to cubic feet for filling liquid tanks with foam (for EPA membranes, flotation devises etc.), multiply gallons by 0.1337. So a 500 gallon tank would need 66.85 cu to fill the tank requiring a TF600SR and TF-200 for a total of 66 cu. yield.
- Tiger Foam contains NO Penta-BDEs as a fire retardant and are both E-84 Fired Rated

Consumer Recommendations
"I just finished using Tiger Foam SR 60. Went from start to finish non-stop using one tip. I preheated the tanks to 85 degrees with a portable heater set on low for two days. I left the tanks in the box, turned them on the side next to each other, opened the tops, and split the heater between the boxes at 16" away for two days. This will heat them to the core. I did have a surface thermometer to monitor them every 6-10 hours, and they never got above 90 degrees."
