Siderise IC-FS Firestop and IC-CB Cavity Barrier Firestop and Smoke Seals Siderise

Siderise IC-FS and IC-CB are manufactured using a 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 “Fire classification of construction products and building elements.”). IC-FS is offered with a 1- or 2-hour fire resistance, with the IC-CB offering 30-minute fire resistance, and can accommodate void widths up to 400mm. In addition to providing an effective seal against the passage of fire, the products are also acoustically absorptive. 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 1mm increments of width to suit the cavity size to provide a tight compressive fit within the void - Please see Table 2 regarding fit type. Each pre-cut IC-FS and IC-CB 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 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 – see Table 1. All fixing brackets are to be mechanically secured to the substructure with suitable non-combustible fixings.
