ABOUT KNAUF INSULATION

GLASS MINERAL WOOL

Our 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 our cured glass mineral wool, we use our 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.

Our 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

Our 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.

WOOD WOOL

Cement-bonded wood wool panels are made from wood shavings to which water and a mix of cement and lime is added. Wood wool panels are ideally suited for improving the acoustics of a space, however, they can also be used for thermal performance and fire safety when combined with a rock mineral wool core.

Heraklith® wood wool panels can be used to comply with performance requirements for buildings. Thanks to their thermal, fire safety and acoustic performance, our solutions contribute to comfortable and aesthetically pleasing working and living environments.

Why Mineral Wool?

Mineral wool is easier to install correctly than other insulants such as rigid boards because it adapts to any slight imperfections in the substrate and knits together, eliminating any air gaps.

Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
