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.
