Attic Insulation - Foam Sealant

Since most houses have too much air leakage into the attic and too little attic insulation, these two improvements should always be completed together. Simply adding more attic insulation will not stop air leaks, because "fluffy" insulation like fiberglass batts and blown-in fiberglass will not stop air leakage. To properly air-seal your attic, our energy technicians need to move aside existing attic insulation and expose all the wall framing, can lights, soffits, vent fans and other details; then they seal all the holes, gaps and cracks they can find. When a blower door test is performed after upgrading the attic air barrier, there will usually be a dramatic reduction in air leakage. Only then is it appropriate to proceed with adding attic insulation. Our team uses an expanding foam sealant to ensure no cracks are left open.
