Attic Air Sealing and High-Performance Insulation Upgrade in Barneveld, NY

This attic improvement project in Barneveld, NY addressed critical energy efficiency and comfort concerns caused by air leakage, insufficient insulation, and inadequate attic ventilation. Openings around wiring penetrations, plumbing pipes, top plates, and the attic access hatch allowed conditioned air to escape into the attic, reducing the home's overall thermal performance and increasing energy consumption.

To correct these issues, a comprehensive air sealing process was completed using one-part spray foam to seal all accessible gaps and penetrations throughout the attic floor. TruSoft blown-in cellulose insulation was then installed to a settled depth of 16 inches, achieving an R-60 insulation value. Additional dense-pack cellulose insulation was installed within the roof rafter bays through the soffits to provide continuous thermal coverage, while a David Lewis insulated scuttle cover was added to minimize heat loss and air infiltration through the attic access opening.

The project was completed with the construction of an insulated catwalk and insulation dams to preserve attic accessibility while protecting insulation performance, along with the installation of a new gable vent to improve attic ventilation and moisture management. These upgrades work together to enhance energy efficiency, increase indoor comfort, and support the long-term performance of the home's building envelope.
