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).
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.
