Knauf Insulation’s Earthwool RainScreen Slab has been certified by the British Board of Agrément for use in high-rise residential applications.
Earthwool RainScreen Slab is said to have a thermal conductivity of 0.034W/mK. When closely butted together the slabs will interlock, eliminating air leakage. It offers superior robustness and durability, with a water repellent additive to preserve its integrity while exposed during construction. It has been wind load tested by the Building Research Establishment to a maximum design pressure of 3,600Pa or 76m/s – the equivalent of a category 5 hurricane.
Earthwool RainScreen Slab is optimised for ease of installation. The improved robustness of the product makes it easy to manoeuvre in place, and it is designed to adapt to minor imperfections in the substrate.
