Application

Rocksilk® RainScreen Slab is used for the thermal insulation of rainscreen façade systems and partially filled masonry cavities. Rocksilk® RainScreen Slab is lightweight but rigid enough to resist the compression forces generated when fixing the insulation slabs to the buildings substrate.

The water repellent additive in Rocksilk® RainScreen Slab provides a further line of defence against rain penetration.

Rocksilk® RainScreen Slab is recommended for use in rainscreen façade systems using a timber, SFS, masonry or reinforced concrete substrate.


Rocksilk® RainScreen Slab is also recommended for use in partial fill applications, against a steel, timber or masonry inner leaf with a masonry outer façade.

Description

Knauf Insulation Rocksilk® RainScreen Slab is a BBA certified rock mineral wool insulation slab designed for use as sheathing insulation in rainscreen façade systems on any building of any height. It is non-combustible, achieving the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.
