Siderise CW-FB curtain wall fireboard forms part of a perimeter barrier firestop and spandrel zone protection system for use with non-fire rated aluminium curtain wall facades.
CW-FB and CW-FS (perimeter barrier and fire stop systems), have been jointly tested in conjunction with non-fire rated aluminium curtain wall assemblies to provide market-leading fire resistance performance for the critical spandrel zone.
Siderise CW-FB Curtain Wall Fireboard is a high-density stonewool board specifically engineered to provide high levels of structural fire protection. Siderise CW-FS Perimeter Barrier comprises a one-piece product with a pre-compressed non-combustible stonewool core and integral aluminium foil facings. In combination, the products can be used in curtain wall façade assemblies requiring enhanced fire resistance performance.
The product combination provides the following advantages:
CW-FB has been tested in both single and double-layer arrangements as part of EN 1364-4 testing.
Siderise CW-FB curtain wall fireboard is a high-density stonewool board specifically engineered to provide high levels of structural fire protection. It has been developed to provide a simple and easy to install method of providing fire protection for non-fire-rated aluminium curtain wall facades.
Based on the experience gained through being the premier supplier to the UK and UAE curtain walling markets, the products represent an unrivalled combination of fully qualified performance, and practical installation and service benefits.
The standard sheet size is 2000mm x 1180mm and may be of benefit when the actual void size is not known or where it varies significantly. It may be provided in pre-cut widths when the void size is known.

The following information is available upon request or via download from the website:
NOTE: * The insulation performance of the panel should only be assumed to be satisfied on the unexposed surface of the seal. Due to the highly conductive nature of metallic facings, it cannot be assumed that the surface temperature of these facings will also satisfy the insulation performance criteria. Evidence of the panel's ability to satisfy the insulation criteria in this specific application should be sought from the panel manufacturer if an insulation performance is required from the panel construction.
