Siderise Insulation is celebrating ten years since first having its curtain wall passive fire protection systems tested to the rigorous BS EN 1364-4 fire resistance standard.
Siderise perimeter fire barrier systems have been specifically designed to provide enhanced fire resistance performance of the perimeter fire seal at the interface between the floor slab and the spandrel zone of curtain wall façades. These incorporate the market-leading Siderise CW-FS Curtain Wall Firestops alongside Siderise CW-FB Curtain Wall Fireboard and mullion protectors, in various arrangements.
Each system has been tested to BS EN 1364-4 in commercially available ‘Type A’ non-fire rated aluminium curtain walls, in arrangements achieving fire ratings of both two hours (EI 120) and three hours (EI 180).
What’s more, since 2017, Siderise CW-FS Curtain Wall Firestops in combination with Siderise CW-FB Curtain Wall Fireboard is currently the only passive fire solution system on the market to have been tested to BS EN 1364-4 with pre-test movement cycling of the fire seal in accordance with EAD 350141-00-1106. The seal is subjected to mechanically induced movement to ±10% of the seal width at 30 cycles per minute (500 cycles) prior to undergoing the BS EN 1364-4 fire resistance test. This is the ultimate demonstration that the Siderise CW-FS—thanks to its unique, vertical-fibre Lamella construction— can withstand the long-term movement of the curtain wall façade without degradation, and still deliver the required fire resistance performance.
