Sealing rim joists

A recent study revealed that you can save an average of $44 a year just by sealing sill plate and rim joist penetrations with an average payback time of 9.4 months.*

Sealing pipe penetrations

Every home is a sprawling network of pipes. That means unwanted air (and pests) can run from the basement, through living spaces and up into the attic.

Air sealing attic

Attics are like a superhighway for unwanted air to enter and wander freely. (Pests, critters and bats travel these roads too.)

Sealing around electrical and cable lines

Holes made for threading wires through walls and studs leave lots of room for air to travel. If there’s ever a fire, these holes can enable flow of air helping to accelerate the spread of flames and smoke.

Air sealing around electrical boxes and outlets

Electrical outlet covers look innocent enough. But the boxes behind them create a heyday for airflow.

Sealing HVAC ducts and pipe penetrations

The same heating, vacuum and air conditioning systems that make a home comfortable create penetrations that can rob living spaces of comfort if they aren’t properly air sealed.

Sealing windows and doors

Windows and doors can give unwanted air an open invitation into a home. But you can quickly air seal the gaps around the frames.


From roof and wall junctions to mechanical and plumbing penetrations, Froth-Pak™ Foam sealant helps reduce energy consumption within the building envelope.
