Insulating an Attic, Adjacent Wall, and Devil's Peak in Fair Haven, NJ

The attic in this Fair Haven, NJ, home lacked proper air sealing and insulation, making it harder to maintain comfortable indoor temperatures and energy efficiency. We air sealed the attic, sealed leaky ducts and vents, and installed TruSoft cellulose insulation. The adjoining room also had a poorly insulated wall and an uninsulated triangular space known as a “devil’s peak,” allowing conditioned air to escape into the attic. We installed SilverGlo foam boards along the wall, sealed gaps with expanding foam, and blew TruSoft cellulose insulation into the triangular space to help maintain comfortable temperatures year-round.
