SIDERISE CW-FB | Curtain Wall Fire Board

Description

Siderise CW-FB Curtain Wall Fireboard is a high-density stone wool board designed to maintain the fire resistance performance of the CW-FS Firestop when used with non-fire-rated curtain wall facades.

The product has been tested in combination with CW-FS to EN 1364-4:2014. This has allowed the CW-FS to achieve third-party certification via Certifire CF563 and Intertek WHI19-32944301.

Standard sheet size: 2000 mm x 1180 mm. Pre-cut sizes are available when spandrel dimensions are provided.

For full installation guidance and performance data, please refer to the product technical datasheet.

Features and benefits:

• Role in Fire Performance: CW-FB Fireboard helps prolong the performance of the curtain wall spandrel assembly preventing the compartmentation line at the perimeter joint from being breached, whilst reducing the likelihood of fire from breaking out through the spandrel panel itself. 
• Testing and Certification: CW-FB Fireboard has been tested multiple times as part of the CW Perimeter Barrier System to EN 1364-4, ASTM E2307, and ASTM E2874 in combination with commercially procurable non-fire rated curtain wall constructions – enabling CW-FS Firestop in the void between the floor assembly and façade to achieve third-party certified fire resistance performances up to 180mins. 
• Tested arrangements: CW-FB Fireboard has been utilised in both single and double-layer arrangements to facilitate the testing of CW-FS Firestop.
