Manufactured using Dual Density technology, the outer surface of each slab features a distinctly higher density than the underside. This provides a firm and robust surface for the application of fixings, while the resilient underside can accommodate unevenness in the substrate.

Once installed, the higher density outer surface works in combination with a factory-applied water repelling agent to give improved resistance to rain ingress during construction.

As demonstrated by independent in-situ laboratory testing, RainScreen Duo Slab helps to reduce the transfer of airborne noise – with results for typical systems as high as Rw 62 dB. Quiet Mark accredited.
