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).
