Blown-in Blanket (BIBS)

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 with the highest attainable R-values available today.

Reduced Air Infiltration

According to Reduced Air Infiltration National Laboratory tests, BIBS reduces air infiltration up to 68% over conventional batt insulation, providing more comfort.

Excellent Sound Control

BIBS is a proven, premium insulation that completely fills around objects inside the wall cavity, resulting in excellent sound control.

High Efficiency R-Values

BIBS high-density insulation delivers the highest R-values on the market today. This maximizes energy efficiency and quickly pays for itself through lower utility bills.


The unique process of placing a measured amount of dense-pack fiberglass blowing wool behind a proprietary, dust-free fabric virtually eliminates settling when installed correctly.


The BIBS system utilizes a proprietary fabric and approved fiberglass blowing wool that is naturally non-combustible.


BIBS is naturally non-flammable, does not support the growth of mold, and contains no added formaldehyde.

Recycled Content

BIBS incorporates fiberglass made with 25% or greater recycled content, delivering maximum performance with minimal weight.

Improved Home Comfort

A consistent density of fiberglass blowing wool helps reduce pathways for moisture, outdoor allergens, pollutants and pests.


All Knauf Insulation products are sustainable, but EcoBatt® Glasswool Insulation with ECOSE® Technology takes that standard to a whole new level. ECOSE Technology is a revolutionary, more sustainable binder based on rapidly renewable bio-based materials. Combine ECOSE Technology with sand—one of the world’s most abundant resources—and a minimum 60% post-consumer recycled bottle glass and the result is Knauf Insulation’s EcoBatt Insulation.


Insulate to save energy An energy efficient house is a better home. With Roxul Comfort Batt ® insulation, it’s also a more comfortable living environment for you and your family. Roxul Comfort Batt helps keep the outside outside, to keep your home warm in the winter, and cool in the summer. That also translates into reduced heating and air conditioning costs – and a house that is easier on the environment. R-value is the measurement of an insulation’s ability to prevent heat flow. The higher the R-value, the more insulating power it provides. Roxul Comfort Batt is available in R15 and R23 to deliver top thermal performance. Additionally, while moisture significantly reduces the R-value of many other popular insulation materials, Roxul Comfort Batt does not store or transfer moisture so the R-value you install will remain the same year after year.

If you live in the Northern half of the US, chances are that a vapor barrier is required to control vapor transmission and minimize condensation in walls and ceilings. While many professional contractors feel that polyethylene is the best choice, you should always consult local building codes when determining whether or not to install a vapor barrier and if so, what product may be best to use.
