6 Important Places to Seal Around Your Home with Foam

Plumbing Penetrations

Pipes around plumbing fixtures create gaps that allow air infiltration and even pests. Place foam sealant straw applicator or gun foam barrel into gaps and fill with foam insulation. Fill opening around pipes slowly to help block drafts.

Electrical Penetrations

There are scores of small gaps and cracks around your phone and cable services, basement, garage and other unfinished areas. When added up, these small cracks can be energy suckers. Place straw applicator or gun foam barrel into gap or crack and lightly spray foam into penetration. Fill seam and trim/paint excess foam. Foam will help reduce drafts, noise and pests.

Rim Joists

Rim Joists are ideal places for cool air and moisture penetration. Spray a 1" layer of foam around the perimeter of the wall cavity and then apply a back fill layer of foam at 1" to fully enclose and air seal the space.

Sill Plates

Openings where sill plates and concrete slab foundations meet let in moisture, air and pests. Apply 1" layer of spray foam along sill plate or apply foam sealant along gap between plate/foundation and sill. Slowly fill seam as you continue to move can along seam.

Exterior Plumbing/Electrical Penetrations

Gaps around air ducts and other exterior plumbing components create air gaps that allow air and pest infiltration. Place foam sealant straw applicator or gun foam barrel into gaps and fill with foam insulation. Fill openings around penetrations and ducts slowly to help block drafts.
