NyRock® Rainscreen 032 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 patented technology, NyRock Rainscreen 032 has a more efficient fibre structure that increases the density of air pockets trapped within each slab. This results in an improved thermal performance when compared to traditional stone wool products.
Once installed, the product’s high density 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, NyRock Rainscreen 032 helps to reduce the transfer of airborne noise - with results for typical systems as high as Rw 60 dB.
