Fiberglass Batt Insulation

Fiberglass Batt Insulation is made from molten glass, usually with 20% to 30% recycled industrial waste and post-consumer content. 

Some fiberglass is unfaced, some is paper-faced with a thin layer of asphalt, and some is foil-faced. Paper-faced batts are vapor retarders, not vapor barriers. Foil-faced batts are vapor barriers. The vapor barrier must be installed toward the warm side.

We use Knauf Insulation EcoBatt® and this insulation doesn’t look like any insulation you’ve ever seen, but that’s because its natural brown color represents a level of sustainability we've never before achieved.

The color comes from ECOSE Technology; a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE Technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE technology are formaldehyde-free and have reduced global warming potential when compared to our products of the past.

EcoBatt Insulation combines sand, one of the world’s most abundant resources, recycled bottle glass and ECOSE Technology to create the next generation of sustainable insulation…naturally from Knauf Insulation.

Knauf Insulation EcoBatt Insulation are cost-effective thermal and acoustical barriers for energy-efficient construction. Their consistent quality, low dust, and clean-cutting resilient fibers make fabrication easy and installation fast. The products can be used in new and retrofit wood and metal frame applications in residential and commercial structures, as well as in manufactured housing applications.
