Frequently asked questions
Should I use spray foam or blown-in fiberglass in my attic?
It depends on the attic. Vented attics with a usable floor often do best with blown-in fiberglass over the joists. Vaulted ceilings, cathedral ceilings, and unvented roof assemblies usually call for spray foam under the roof deck. We'll inspect and recommend the right approach.
Will new attic insulation stop my ice dams?
In most cases, yes — combined with proper air sealing. Ice dams are caused by warm air leaking into the attic and melting snow on the roof. The right attic insulation and air sealing package addresses the root cause.
How long does attic insulation last?
A properly installed spray foam or blown-in fiberglass attic system can perform for decades. Modern products don't settle or break down the way some older insulation did.
