Behind the walls of the most energy-efficient homes and buildings is the BIBS system, the industry-leading residential and commercial high-performance insulation system. The BIBS system is a proven, state-of-the-art insulation system utilizing specially manufactured fiberglass blowing wools installed in the walls, floors, attics, and cathedral ceilings behind a proprietary fabric. The system forms a seamless blanket of insulation that completely fills around pipes, wires, and other objects inside the cavity to increase thermal efficiency and eliminate costly voids and air gaps. This process helps provide you with the highest, full cavity effective R-values attainable today.
