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
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. RAINSCREEN DUO SLAB is a BBA-approved insulation product, that in addition to thermal comfort, provides an independently-tested acoustic benefit.
