90mm Rockwool Dual Density Slab for Insulated Renders - 1200mm x 600mm (pack of 2)

90mm Rockwool Dual Density Slab is a specialised dual density rock wool board that can be used for external wall insulation, where the higher density face of the board can take renders directly, while the lover density inner face can accommodate slight imperfections in the fabric of the building. By using these Dual Density boards for your external wall insulation system, you also gain the added benefit of acoustic insulation -- the open porous structure of the rock wool can absorb and reduce the impact of sound, enabling homeowners to enjoy a comfortable, quiet internal environment. Rock wool is made from molten volcanic rocks, a natural material, therefore completely non-combustible. They have achieved a Euroclass rating of A1 for non-combustibility, the highest rating that an insulation material can achieve.
