There is a broad spectrum of insulation materials available on the market, with an equally broad variance in form, performance, sustainability, cost-effectiveness and availability.
All our mineral wool products meet the highest specifications and have demonstrated excellent rounded performance in the most demanding projects, including those built to the Passivhaus standard.
Glass Mineral Wool
Our high-performance cured glass mineral wool insulation solutions contain up to 80% high quality recycled materials, to which is added sand, limestone and soda ash before being melted in a furnace. The molten glass is spun to form millions of fine strands of wool. We use our proprietary and revolutionary bio-based binder, ECOSE® Technology, 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 rigid slab, and its thermal insulation value.
Our high-performance Blowing Wool is an un-bonded, virgin fibrous glass blowing insulation, which is produced in the same way as the glass mineral wool, however, it is produced as a loose-fill product to be blown into cavity walls, partitions, timber frame walls and ceilings.
Rock Mineral Wool
Our rock mineral wool insulation solutions are mainly made from volcanic rock, typically basalt and/or dolomite. An increasing proportion is now recycled material from slag, a waste product from blast furnaces. 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 or wired mattresses. Most of our rock mineral wool products use our ECOSE® Technology.

wood wool
Cement-bonded wood wool panels are made from wood shavings, to which water and a mix of cement and lime is added. The wood wool basic recipe was invented back in 1908, and since then, we have continued to improve our panels.
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 comply with performance requirements for buildings. Thanks to their thermal, fire safety and acoustic performance, our solutions contribute to safe, comfortable and aesthetically pleasing working and living environments.
