Siderise EW Closed State Cavity Barrier and Firestop

Description

Siderise EW Systems have been developed to provide a tested method of sealing external wall cavities to provide resistance to the passage of fire in external masonry constructions.The EW product range is for use as a Cavity Barrier or Firestop in accordance with the guidance supporting the national Building Regulations.

Friction fit installation is available throughout the range to support installation with ‘green’ brickwork, which brings considerable advantages to the construction timeline.

In addition to providing an effective seal against the passage of fire, the products are also acoustically absorptive. These products represent an ideal combination of fully qualified performance and practical installation. 3rd party product approval is provided by IFC Certification (IFCC 1830).

Siderise EW 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 BS EN 13501-1:2018).

Features and benefits:

• Installation overview: The product installation requires fixing brackets and jointing tape all supplied by Siderise as part of a complete package. Friction fit options for the entire product range, both horizontal and vertical, and void range, 20-400mm voids, means products do not need to be installed with compression and can be applied to wet brickwork without compromising the stability of the wall structure.
• Accommodates penetrations: The stone wool Lamella composition allows EW Cavity Barrier and Firestop to be effortlessly notched. This means components commonly interrupting the firestopping line e.g. masonry support brackets, can be easily accommodated
• Third-party tested and certified: Tested to BS EN1366-4:2006+A1:2010 and BS EN 1366-4:2021 with third-party certification through IFCC 1830, which covers both horizontal and vertical applications and incorporates fixing brackets and aluminium foil jointing tape
• CCPI assessed: EW Closed State Cavity Barrier and Firestops products have achieved CCPI assessed status (Applies to EW-CB30, EW-FS60 & EW-FS120 only). 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
• Tested and certified for cavities up to 400mm: To suit specific cavity barrier and firestop specification requirements, EW Cavity Barrier and Firestop is available with fire resistance performance ratings ranging from 30mins to 120 mins for 20-400mm voids both horizontally and vertically. 
• Tested with masonry supports and DPCs: To demonstrate compatibility and provide assurance that performance is not compromised, EW Cavity Barrier and Firestop incorporating DPCs has been tested to BS EN 1366-4:2021, and EW-FS120 has been tested with masonry support angles with differing levels of penetrations
