PERIMETER BARRIERS Siderise CW perimeter barrier and fire stop systems
AND FIRE STOPS FOR offer an extensive range of solutions for fire stop, smoke
CURTAIN WALLING stop and sound barrier requirements in all architectural
cladding panel applications.

Based on the experience gained through being the
premier supplier to the UK curtain walling market, the
products represent an unrivalled combination of fully
qualified performance, practical installation and service
benefits.

The primary function of the CW system is to maintain
continuity of fire resistance by sealing the void between
the compartment floors or walls and the external
curtain wall both horizontally and vertically.

PRODUCT DESCRIPTION

Siderise perimeter barriers and fire stops for curtain
walling use is a unique method of manufacture that
provides a resilient lateral compression. This facilitates
installation ensuring the requisite tight fit and enhances
fire integrity.
The materials throughout the range comprise of a one-
piece product with a pre-compressed non-combustible
stone wool core. The products also have integral
aluminium foil facings to provide an overall Class A1 rating
(to EN 13501-1) and excellent resistance to smoke.
The systems can offer tested fire rating options ranging
from 30mins to 3 hours and can accommodate void
widths up to 600mm.
In addition to providing an effective seal against the
passage of smoke and fire the products will also function
as an effective acoustic barrier and plenum lining.
