What is Fiberglass Insulation?

Colonial offers an extremely high-quality insulation made by Knauf. The glass mineral wool contains a high concentration of the world’s most abundant resources – sand – and a high degree of recycled bottle glass bonded with ECOSE technology.

ECOSE®

ECOSE is a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the band 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 binder traditionally used in glass mineral wool products. ECOSE products have formaldehyde-free and have reduced the global warming potential when compared to products of the past.
