Siderise CW-FS perimeter barrier and fire stop systems use a unique method of manufacture which provides a resilient lateral compression. This facilitates installation, ensuring the requisite tight fit and enhancing the fire integrity of the product.

Siderise CW systems are manufactured using a unique method that provides resilient lateral compression. This facilitates installation, ensuring the requisite tight fit and enhancing the fire integrity of the product. Throughout the range, the materials comprise a one-piece product with a pre-compressed non-combustible stone wool core. The products also have integral aluminium foil facings to provide an overall Class A1 rating (to EN 13501-1). The systems can offer tested fire resistance options ranging from 30 mins to 3 hours (3 hours to EN 1364-4 only) and can accommodate void widths up to 600mm (600mm voids to EN 1366-4 only). In addition to providing an effective seal against the passage of smoke and fire, the products are also acoustically absorptive. 

Individual products within the range are as follows:

CW-CB30 (Cavity Barrier) can be applied to voids sizes of 20–350 mm horizontally and 20–450 mm vertically with a resistance to fire of 60 minutes integrity (horizontally orientated) and 90 minutes integrity (vertically orientated) and 30 minutes insulation when tested to EN 1366-4

CW-FS60 (Fire Stop) can be applied to voids sizes of 20–300 mm horizontally and 20–450 mm vertically with a resistance to fire of 90 minutes integrity and 60-minute insulation when tested to EN 1366-4

CW-FS120 (Fire Stop) can be applied to voids sizes of 20–350 mm horizontally and 20–450 mm vertically with a resistance to fire of 120 minutes integrity, and 120 minutes insulation when tested to EN 1366-4. Additionally, CW-FS120 can be applied in voids 20–250 mm horizontally with a resistance to fire of 120 minutes integrity and 120-minute insulation when tested to EN 1364-4

CW-FS180 (Fire Stop) can be applied in voids 20–250 mm horizontally with a resistance to fire of 180 minutes integrity and 180 minutes insulation when tested to EN 1364-4

CW-FS60-X (Fire Stop) can be employed for larger voids 301–600mm horizontally and 451-600mm vertically with a resistance to fire of 60 minutes integrity and 60-minute insulation to EN 1366-4

 

Please refer to the manufacturer's supplied technical data sheet for detailed tables and information on each product in the range and supporting test standards.

 

Standard Systems:

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

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 1mm increments of width to suit the cavity size to provide a tight compressive fit within the void - Please see Tables 2-4 of the 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 galvanized mild steel in a flat form that is complete with a pre-notched facility for folding on site. Brackets are also available in stainless steel.

All hole positions are to be drilled to suit the varying site conditions. Different size brackets are available according to the cavity size – please see the manufacturer's technical data sheet.

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

Façade deflection should be taken into consideration with respect to installation compression, please see ‘Movement Characteristics’ in the manufacturer's technical data sheet.

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. See product datasheets for more detail.  
  • CCPI verified status: CW-CB30, CW-FS60, CW-FS120 and CW-FS180 have all achieved CCPI verified status. This provides clear assurance 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 long-term durability, CW-FS Firestop has been put through accelerated Type X 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 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 EN 15804+A2:2019 and ISO 14025.
