What is BIBS® Technology?

The Blow-In Blanket® system or the BIBS® system is a proven, state-of-the-art insulation system utilizing specially manufactured fiberglass blowing wools installed in the walls, floors, attics, or 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 maximize thermal efficiency and performance of the building envelope. The BIBS® system provides the highest attainable R-values available today. Check out the video below to learn more.


Higher Efficiency R-Values

The BIBS system is a high-density insulation solution for commercial and residential building applications that delivers higher R-values than traditional insulation alternatives, saving you costly heating and cooling expenses.

Reduced Air Infiltration

National laboratory tests show that the BIBS system reduces air infiltration up to 68% over conventional batt-type insulation alternatives, providing more comfort.

Excellent Sound Control

The BIBS system completely fills around pipes, wires and other objects inside the cavity to help eliminate air gaps, resulting in excellent sound control.

Improved Home Comfort

Many factors influence the comfort of your home. A consistent density of fiberglass blowing wool helps reduce pathways for moisture, outdoor allergens, pollutants, and pests making a home more comfortable.


The BIBS system is naturally non-flammable. The system utilizes a proprietary fabric and approved fiberglass blowing wools that meet ASTM C764 Testing Criteria for smoldering combustion and ASTM E136 for non-combustion.

Recycled Content

In addition to its energy-saving heating and cooling costs and custom-fit qualities, the BIBS system incorporates fiberglass blowing wools made with 25% or greater recycled content.
