Attic Spray Foam Insulation in Pittsburgh

In a typical Pittsburgh home, 25-40% of heating and cooling energy escapes through the attic. It's the single biggest opportunity to improve your home's energy efficiency.

Two approaches to attic insulation:

Unvented (hot roof) — Spray foam is applied directly to the underside of the roof deck, transforming your attic into conditioned space. This is the premium approach. It makes attic spaces usable, protects HVAC equipment in the attic, and eliminates ice dams. Closed-cell foam provides R-30+ in just 5 inches.

Vented attic — Spray foam is applied to the attic floor, sealing all air bypasses (plumbing penetrations, electrical boxes, duct chases, top plates). This is the most cost-effective approach when the attic doesn't need to be conditioned.

Both approaches dramatically outperform fiberglass batts because spray foam seals air leaks AND insulates simultaneously. Fiberglass alone does not stop air movement — which is why you can have R-38 fiberglass in your attic and still have ice dams and high energy bills.

Ice dams are a Pittsburgh epidemic. They form when heat escaping through an under-insulated attic melts snow on the roof, which refreezes at the eaves. Spray foam stops this cycle by keeping attic temperatures consistent — no more heat reaching the roof deck.
