Curtain walling is a non-structural façade system commonly used on mid- to high-rise buildings, valued for its clean, modern appearance and ability to protect occupants from the elements while maximising floor-to-floor natural daylight. To ensure long-term fire safety, these glazed façade systems must incorporate effective compartmentation solutions that deliver reliable fire resistance and are proven to perform under building movement and façade deflection.

Our extensively tested range of passive fire protection products and systems for curtain wall façades is purpose-designed to provide the required fire resistance for typically non-fire-rated, window-framed building envelopes. 

Ensuring effective compartmentation between the floor slab and the façade—an area referred to as the spandrel—is critical to the fire safety of glazed façades. Siderise® systems are third-party tested and certified slab edge CW Perimeter Barrier Systems which not only inhibit fire spread but help preserve the performance of the spandrel assembly therefore the stability of the curtain wall— all whilst withstanding façade and floor slab movement over the lifetime of the building.

Siderise® systems incorporate a combination of the CW-FS Firestop and CW-FB Fireboard to provide protection for the curtail wall spandrel panel.
