Injection Foam Insulation

• Tripolymer wall injection foam is a cold-setting foam that is injected (not sprayed) into an existing wall system usually from the outside.
• This makes it ideal for retrofitting existing older and building where it is not necessary to disturb the interior wall finishes such as plaster and lathe, wood paneling, drywall, etc. The foam flows easily into hard-to-reach cavities, completely filling the cavity and hardening within 10 SEC to 60 SEC after injection.
• Tripolymer has an R-value of R5.1 and provides an air seal thus stops air infiltration, reduces sound transmission, and is fire proof, thus increases the fire safety of many types of building construction.
• Tripolymer can be used in virtually any type of building construction: wood framed, commercial masonry blocks, and behind masonry or brick walls.

How is Tripolymer installed?

Seal It will remove a course of clapboards, vinyl siding, or as many outside shingles as necessary at mid-wall height to drill the 3 IN cavity holes. A 1 IN DIA hose is then inserted into the hole to the bottom of the wall cavity. The foam is then turned on, filling the cavity as the hose is withdrawn. The process is then repeated from the top of the wall cavity.

Once the foam injection process is complete, then Seal It will plug the drilled holes and will reattach or replace the siding as necessary. Normally, Seal It can injects 3.5 IN to 4 IN of foam into a 2 IN X 4 IN stud wall for an R18 to R20.
