Description
Rocksilk RainScreen Slab is a rock mineral wool slab containing
a water repellent additive, specially developed for rainscreen
cladding applications.
Application
Rocksilk RainScreen Slab is used for the thermal insulation of
rainscreen cladding systems.
RainScreen cladding systems typically comprise outer cladding
panels that are bolted to a supporting framework of rails, which
are supported by cleats fixed back to the building structure. A
layer of insulation is fixed independently against the building
substructure using proprietary insulation fasteners.
An airspace separates the insulation from the outer cladding
panels. This allows wind driven rain to run down the back of the
rainscreen panels, providing additional protection to the
insulation layer.
Rocksilk RainScreen Slab is recommended for this application, as
it is lightweight but rigid enough to resist the compression forces
generated when installing the insulation slabs to the masonry
substrate. The water repellent additive in Rocksilk RainScreen Slab
also provides a further line of defence against rain penetration of
the external wall.
Standards
Rocksilk RainScreen Slab is made from non-combustible inorganic
rock wool, defined as mineral wool in BS 3533: 1981 and is
manufactured in accordance with BSI Quality Assurance Standard BS
EN ISO 9001: 2000.
