Leading the change in smarter insulation solutions for a better world
Knauf Insulation’s aspiration is to be the world’s most trusted insulation partner providing high performing and smart insulation solutions and services for a better world.
The only UK manufacturer of Glass and Rock Mineral Wool insulation
Glass Mineral Wool
Their glass mineral wool insulation is made with up to 80% recycled content (including glass from windows, bottles and jars), to which sand, limestone and soda ash is added before being melted in a furnace. The molten glass is spun to form millions of fine strands of wool.
To manufacture cured glass mineral wool, they use a unique plant-based binder, ECOSE®, to bind the mineral wool together to form a mat of material which is then cured in order to form the final product. The density of the product determines whether the insulation is a lightweight quilt supplied in rolls, a flexible slab or a slab, and its thermal insulation value.
Their blown glass mineral wool is an un-bonded, virgin fibrous insulation, which is produced in the same way as the cured glass mineral wool, however, it’s not cured but left as a loose-fill product to be blown into various applications.
Rock Mineral Wool
Their rock mineral wool insulation solutions are mainly made from volcanic rock, typically basalt and dolomite, and around 35% recycled content (recycled material mostly from the steel industry along with customer production waste).
The raw materials are melted and then spun into fine strands of wool. A binder is used to bind the wool together to form a mat of insulation, which is then cut into slabs. Most of our rock mineral wool products are made with our ECOSE® binder.
