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 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. 

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. 

Industry-leading Compression Packaging

Our industry-leading compression packaging technology (9:1) allows for more product per pack, therefore less packaging used, fewer lorries on the roads and reduced transport carbon emissions. All of which contributes to a low lifecycle impact. It also means our customers require less storage space, and less carrying and handling when compared to other products.

KrimpactTM Technology

A number of our Rock Mineral Wool products are manufactured using KrimpactTM Technology which gives our products consistent density throughout, combined with superior impact and compression resistance. Krimpact Technology aligns fibres in the mineral wool in such a way as to dramatically increase compressive strength and its ability to resist heavy loads.
