Glass Mineral Wool is lightweight, easily installed and provides outstanding levels of thermal performance and acoustic absorption. Our wide range of non-combustible Glass Mineral Wool products are designed to provide solutions for all types of roofs, walls and floors in new build and refurbishment of both residential and non-residential buildings. Our high performance Glass Mineral Wool insulation solutions contain high quality recycled glass, to which sand, limestone and soda ash are added before being melted in a furnace, and spun to form millions of fine strands of wool. We use our proprietary and revolutionary ECOSE® Technology binder to bind the mineral wool strands together to form a mat of material which is then cured in order to form the final product. ECOSE® Technology is our unique bio-based binder* which is used in the manufacture of all of our Glass Mineral Wool products. Invented over 10 years ago and still unique to Knauf Insulation, it is very much central to our sustainability strategy.
