ROCKWOOL® RAINSCREEN DUO SLAB®
ROCKWOOL® RAINSCREEN DUO SLAB® is a stone wool insulation product specifically developed for use within ventilated cladding systems, as well as sealed systems such as curtain walling.
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, ROCKWOOL® RAINSCREEN DUO SLAB® helps to reduce the transfer of airborne noise – with results for typical systems as high as Rw 62 dB.
