The Blow-in-Blanket System, or BIBS, gives each building a custom-designed, seamless, thermally efficient, sound‑reducing blanket that completely fills any void. BIBS is a patented process that blows fiberglass insulation into cavities behind netting. The process requires installation techniques designed specifically for BIBS. When installed at recommended density levels, it yields an R-15 in 2"x4" construction and an R-23 in 2"x6" construction.
National laboratory tests show the Blown-in-Blanket System reduces air infiltration up to 68% over conventional batt‑type insulation. Because Blown-in-Blanket System system uses higher density insulation, it is able to deliver higher R-Values. Blown-in-Blanket System completely fills around objects inside the wall cavity, resulting in excellent sound control. The patented process of injecting the fiber behind a dust free netting eliminates settling.
The Blow-in-Blanket System, using fiberglass insulation, meets HH‑1‑1030B Testing Criteria for smoldering combustion and ASTM E 136 for non-combustion.
