SIDERISE® Cavity Barriers

SIDERISE® provides a simple, effective fire break barrier to stop the spread of fire between floors

SIDERISE® have been developing bespoke fire, thermal and acoustic insulation solutions for over 4 decades.

The SIDERISE® fire barrier allows for continuous ventilation and drainage behind the cladding whilst providing a hot smoke and fire seal when triggered. Both SIDERISE® products are made up of a non-combustible stone mineral wool lamella core, faced on exposed surfaces with a class O fire rated reinforced aluminium foil. This system includes products for both horizontal and vertical solutions.

The following SIDERISE products are available.

    • SIDERISE RH ‘Open State’ horizontal cavity barriers – RH50(G/S) and RH25(G/S)
    • SIDERISE RV vertical cavity barriers
    • SIDERISE foil tape: Type RFT 120/45
    • SIDERISE support brackets – galvanised or stainless steel options

SIDERISE® RH ‘Open State’ horizontal cavity barriers are specifically used in drained and ventilated facades. The system will drain any moisture within the façade construction, as well as maintain airflow. The system will provide an effective hot smoke and fire seal in the case of fire. The SIDERISE®  ‘Open State’ systems are available for cavities up to 25mm RH25(G/S) and 50mm RH50(G/S).

SIDERISE®  RV vertical cavity barriers fully seal the void between the external envelope and internal structure. The cavity barrier assists ventilated facades to function by maintaining air-pressurisation. The products unique stonewool lamella core enables the vertical barriers to accommodate movement, associated with rainscreen facades. Intersections between horizontal and vertical cavity barriers are simply abutted.

SIDERISE® cavity barriers have been tested and approved by Warrington Fire Research Centre (WFRC) and the barriers are available to suit 30, 60, 90 and 120 minute applications. SIDERISE® is suitable for use in cavities widths up to 425mm wide and is able to close a 25mm and 50mm gap under fire conditions as well as being economical and easy to install.

SIDERISE® is supplied in 1200mm long strips and can be pre-cut in width to suit advised void size.
