Earthwool RainScreen Slabs
For the thermal insulation of rainscreen cladding systems
Earthwool RainScreen Slab is a semi-rigid, lightweight, non combustible rock mineral wool slab containing a water repellent additive, specifically designed for use in rainscreen cladding systems.
Earthwool RainScreen Slab is odourless, rot proof, non hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.
The U-value of a proprietary rainscreen cladding system is dependent on the degree of thermal bridging in the system. Typically 100mm of Earthwool RainScreen Slab will achieve a U-value of 0.35W/m2K, but Knauf Insulation recommend consulting individual rainscreen cladding manufacturers for U-values appropriate to their systems.
Earthwool RainScreen Slab is classified as Euroclass A1 to BS EN 13501-1, Class 1 Surface Spread of Flame to BS 476:Part 7:1997 and Class O to the Building Regulations.
Lightweight but rigid and robust
Designed to adapt to minor imperfections in substrates
