We make homes and buildings more energy efficient every day. Knauf Insulation North America manufactures thermal and acoustical glass mineral wool insulation for residential, commercial, industrial, marine, original equipment manufacturer and metal building applications. A core tenet in our production is conservation of the environment we share. Our products are made with sand, the world's most abundant resource, minimum 50% post-consumer recycled glass, and ECOSE® Technology, a revolutionary and more sustainable binder. ECOSE Technology is formulated from rapidly renewable, bio-based materials rather than petroleum-based chemicals commonly used in traditional fiberglass insulation. It does not contain phenol, formaldehyde, acrylics or artificial colors. "It's time to save energy!"
