Spray Foam Insulation

Attic spray foam that moves the thermal boundary to the roof deck and calms the whole house

Foam on the underside of the roof deck turns a hot, vented attic into a conditioned space that is far more stable through every season.

Attic Spray Foam

Tennessee summer sun can heat an attic past 130 degrees, and ducts, air handlers and storage live up there. Spraying foam on the underside of the roof deck brings the attic inside the insulated envelope, so the equipment works in a much milder space and air no longer pours through ridge, soffit and gaps.

We install attic spray foam on homes across Nashville and Middle Tennessee. Our crews seal the roof deck, gables and eaves, apply the right foam depth for the rafters, leave access paths clear and walk you through how an unvented attic changes ventilation and maintenance.

FAQ

Common questions about attic spray foam

Will spray foam on the roof deck void my roof or shingles?

Roofing manufacturers have their own guidance on unvented roofs, and we review it with you before we spray.

What happens to my attic vents?

In a foamed roof deck the soffit and ridge vents are blocked off because the attic is now inside the thermal boundary.

Can I still walk in the attic?

Yes. We leave clear access and the foam finish can be walked beside, not on, so use the framing as before.
