Fire resistance

BIBS insulation meets HH-I-1030B testing criteria for smoldering combustion and ASTM E136 criteria for noncombustion. The flame spread rating is 0, and the smoke development rating is 5.

Installation standards and practices

The Blow-In-Blanket System must be operated by a certified BIBS contractor. This requirement should help maintain a consistent quality of installation of the product. Natural ventilation must be
