Low lambda non-combustible stone wool insulation for ventilated facades.
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.
The product can be fitted around brackets and other awkward details, and when tightly butted, adjacent slabs effectively ‘knit’ together to provide a continuous insulating layer, reducing heat losses that would otherwise be caused by gaps.
For optimum thermal performance in framed structures, combine NyRock Rainscreen Slab 032 with NyRock Frame Slab 032.
