Knauf EcoBatt Fiberglass Insulation Batts with ECOSE Technology are a flexible glass mineral wool batt insulation made from sand and over 50% recycled glass bottles bonded with ECOSE Technology. Fiberglass insulation is the most cost effective way to increase thermal performance. By reducing energy usage, fiberglass insulation allows your heating and cooling systems to operate with greater efficiency, which decreases energy use, may reduce your energy bills and limits the release of greenhouse gases into the atmosphere. Fiberglass insulation helps you — and all of us — do more while consuming fewer resources.
