Continuous insulation
Spray foam expands around rafters, corners, and penetrations, giving attic insulation fewer gaps.

Comfort starts at the roofline
Attic Insulation
Use attic spray foam insulation to turn a draft-prone roofline into a continuous part of the building envelope.
The application
Designed around
your building.
Attic insulation is one of the strongest opportunities to improve year-round comfort. Spray foam insulation follows the roof deck, reaches irregular framing, and seals small gaps that conventional insulation may leave behind. Our Belleville crew reviews the roof assembly, ventilation, access, and existing insulation before recommending open-cell or closed-cell spray foam. The right spray foam depth creates consistent insulation across slopes, corners, and roofline transitions.
Why it works
Performance starts
with continuous coverage.
Consistent rooms
Spray foam insulation at the roofline helps upper floors hold steadier temperatures through seasonal swings.
Useful attic space
Roofline spray foam can bring equipment and storage inside a better insulated, air-sealed envelope.
