SIDERISE CW-FS Perimeter Barrier and Fire Stop for Curtain Walling

Siderise Perimeter Barriers and Fire Stops for Curtain Walling use a unique method of manufacture which provides a resilient lateral compression. This facilitates installation, ensuring the requisite tight fit and enhances fire integrity.

Throughout the range, the materials comprise a one-piece product with a pre-compressed non-combustible stonewool core. The products also have integral aluminium foil facings to provide an overall Class A1 rating (to EN 13501-1) and excellent resistance to smoke.

The systems can offer tested fire rating options ranging from 30 to 180 minutes and can accommodate void widths up to 600 mm with individual products within the range as follows:

• CW-CB30 (Cavity Barrier), CW-FS60(Fire Stop) and CW-FS120(Fire Stop) can be applied to voids sizes of 20–300 mm horizontally and 20–450 mm vertically and have resistance to fire ratings of 30, 60 and 120 minutes respectively.
• CW-FS180(Fire Stop) can be applied horizontally in voids 20–250 mm with a resistance to fire rating of 180 minutes.
• CW-FS60-X (Fire Stop) can be employed for larger voids 301–600 mm with a 60 minute resistance to fire rating.

Please refer to manufacturers supplied technical data sheet for detailed tables and information on each product in the range as well supporting test standards.

In addition to providing an effective seal against the passage of smoke and fire, the products will also function as an effective acoustic barrier and plenum lining.

Standard Systems:

The materials can be either supplied as pre-cut units to suit a specified void size or in sheet form for cutting on site. 

Standard sheet products are supplied 1200 x 1200 mm which may prove beneficial when the actual void size is not known or where it varies significantly. Please note that when ordered in sheet form, the requisite quantity of fixing brackets needs to be purchased separately.

Pre-cut strips are available in 1 mm increments of width to suit the cavity size to provide a tight compressive fit within the void - Please see manufacturer's technical data sheet regarding fit type. Each pre-cut CW unit is supplied with appropriate fixing brackets as part of the system.

The standard fixing brackets are supplied in 1mm galvanised mild steel in a flat form that is complete with a pre-notched facility for folding on site. 

All holes are to be drilled to suit the varying site conditions. Different size brackets are available according to the cavity size.

All fixing brackets are to be mechanically secured to the substructure with suitable non-combustible fixings.
