Learn moreAvailable in a wide range of thicknesses, Knauf Rocksilk® RainScreen Slab, is the perfect insulation solution for rainscreen façade systems and masonry cavities. BBA-certified and suitable for use in all buildings of any height, this rock mineral wool insulation is non-combustible and boasts a Euroclass A1 fire rating, giving you peace of mind that your building is safe and secure.
Rocksilk RainScreen Slab is made using Knauf's unique bio-based binder, ECOSE® Technology, and has a thermal conductivity of 0.034 W/mK, offering exceptional thermal insulation. Plus, with its water-repellent additive, the slabs will maintain their integrity when exposed on-site, providing reliable, long-lasting insulation.
The slabs are lightweight yet rigid enough to resist compression forces generated when fixing them to the building substrate, and their engineered design adapts to minor imperfections in the substrates. What's more, they are odourless, rot-proof, non-hygroscopic, and do not sustain vermin or encourage the growth of fungi, mould, or bacteria.
Whether you're working on a rainscreen façade system using a timber, SFS, masonry, or reinforced concrete substrate or a partial fill application against a steel, timber, or masonry inner leaf with a masonry outer façade, Knauf Rocksilk® RainScreen Slab is the perfect insulation solution for your project. And with a life equivalent to that of the wall structure in which it is incorporated, you can trust that it will provide reliable insulation for years to come.
