Siderise CW-FS Firestop and CW-CB Cavity Barrier

CW-FS Firestop, functioning as a slab edge perimeter seal in our CW Perimeter Barrier System, has been comprehensively tested to BS EN 1364-4:2014, ASTM E2307-20 and ASTM E2874-19 curtain wall fire test standards.

It has also been tested standalone to BS EN 1366-4:2006+A1:2010 to determine its performance when used in the vertical orientation for curtain walling, and in both the vertical and horizontal orientation for use between two fixed elements e.g. pre-cast and composite sealed architectural wall systems.

CW-FS120 and CW-FS180 are certified to deliver up to 2 hours (E 120 / I 120) and 3 hours (E 180 / I 180) fire resistance respectively. Please see the product technical data sheet for more details.  

CW-CB30, CW-FS60, CW-FS120 and CW-FS180 have all achieved CCPI assessed status. This provides greater confidence that the product information we publish about these products is clear, accurate, up-to-date, accessible, and unambiguous — and is checked and managed by competent people. 

To confirm in-application durability and robustness in its ability maintaining its form and performance when exposed to specific use conditions, CW-FS Firestop has been put through EOTA Technical Report 024 ‘Type X’ accelerated age testing - the harshest category, which replicates exposure to rain, UV, high temperatures, and frost and thaw cycles.

CW-FS Firestop has passed the relevant European Technical Assessments for CE marking (ETA 21/0297). This includes undertaking movement cycling to simulate real world façade deflection before fire testing to BS EN 1364-4. This gives relevant and robust test evidence for containing fire in non-fire rated curtain wall systems. 

The environmental impact of all products in the CW-FS Firestop and CW-CB Cavity Barrier range has been assessed through a lifecycle assessment (LCA) and is detailed in a third-party verified EPD (Environmental Product Declaration) created in accordance with BS EN 15804+A2:2019 and ISO 14025.
