Blow-in blanket by Ark-Seal Inc. International

The company’s Blow-In-Blanket is tailored toward custom homebuyers by offering thermal protection and sound control. When fiberglass insulation is blown behind a special fabric it completely fills all cavities, especially around pipes and wiring. The blanket offers high density and R-value (R 15 on 2x4 and R 23 on 2x6). The BIBS reduces air infiltration 68 percent more than conventional insulation and provides strong sound control. It is used on both steel- and wood-stud construction.
