Buy Mineral Wool Insulation Slabs & Rolls

Glass mineral wool is made from sand and recycled glass, limestone and soda ash. These are the same ingredients that are used to make familiar glass objects such as window panes or glass bottles. The glass is spun to form millions of fine fibres. A resin is used to bind the fibres together to form a mat of material that is characterised by long fibres that offer good tear strength.

Thermal Insulation properties are ideal as lightweight loft / roof void insulation, cavity wall insulation, external wall, and metal framed building cladding rolls. Acoustic Insulation offers sound insulation (absorption) within partitions and floors, as well as excellent fire properties -

Both stone and glass mineral wool offer both thermal and acoustic insulation properties, and are resistant to fire, commonly non-combustible and suitable for temperatures up to 230°C,

While PIR and Phenolic boards offer better thermal properties than stonewool slabs of a similar thickness, rock wool products provide superior acoustic solutions.

Mineral wool, stone or glass,  offers the further benefit of being significantly less likely to introduce condensation into elements of a construction, than their aluminium faced counterparts.
