Siderise CW-FS Firestop and CW-CB Cavity Barrier

Description

Siderise CW-FS firestop & CW-CB cavity barrier systems offer an extensive range of solutions for fire-stopping, horizontal perimeter seals, and acoustic barrier requirements in all curtain wall applications. CW systems may also be used in firestop and cavity barrier applications in conjunction with weathertight façade systems such as precast concrete cladding, composite & architectural cladding panels.

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.

CW systems’ unique product construction also provides the ability to accommodate movement for the life of the building.

Features and Benefits:

• Comprehensively tested: CW-FS Firestop is a key component of our CW Perimeter Barrier Systems that have been comprehensively tested to EN 1364-4, ASTM E2307 and ASTM E2874 curtain wall fire test standards. 
• Fire resistance: CW-FS120 and CW-FS180 are certified to deliver 2 hours (E 120 / I 120) and 3 hours (E 180 / I 180) fire resistance respectively. 
• CCPI assessed status: CW-CB30, CW-FS60, CW-FS120 and CW-FS180 have 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. 
• 60 year design life: 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.
• CE marked with movement capability +/- 10%: 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 the most relevant and robust test evidence for containing fire in non-fire-rated curtain wall systems.
• Third-party verified EPD: 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.
