The Blow-ln-Blanket System (BIBS)

A technological variation from the simple blown-in loose-fill fiber­glass insulation discussed in Chap. 7 is the Blow-ln-Blanket System (BIBS). Developed by Ark-Seal, Inc., in 1985, BIBS is a patented and trademarked system that is installed exclusively by certified contractors using proprietary equipment and approved
ingredients. The system is used in residential and commercial con­struction for thermal and acoustical insulation. The system also can be used to insulate floors, attics, and cathedral ceilings. BIBS insulation technically could qualify as a loose-fill insulation prod­uct because the netting used in this system is actually creating the wall cavity. The presence of a binder is the reason it is included in this chapter (Figs. 9.5 and 9.6).

The Blow-ln-Blanket System (BIBS)

In 1998, Ark-Seal unveiled a dry product, proprietarily known as the Blow-In-Blanket Dry System. R-values for a 2 X 4 wall and a 2

X 6 wall are R-15 and R-23, respectively. As with the original sys­tem, fiberglass is blown in behind a special netting. Since the insu­lation is dry, gypsum wallboard can be applied immediately. The original Blow-In-Blanket System will be discussed in this chapter.
