Rockwool Rainscreen Duo-Slab 1.2m x 600 x 90mm Pack of 4

The Rockwool Rainscreen Duo-Slab 1.2m x 600 x 90mm (L x W x T) is a non-combustible ventilated cladding insulation product made of stone wool. Specifically developed for use within ventilated cladding systems and sealed systems such as curtain walling.The slab is BBA-approved providing thermal comfort as well as independently-tested acoustic benefit. 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.
