Cavity Fire Barriers & Lamatherm

Lamatherm provides a simple, effective fire break barrier between floors, that sits behind the rainscreen cladding and stops the spread of fire in the airflow cavity behind the cladding.

Lamatherm is manufactured by Siderise, who have been developing bespoke fire, thermal and acoustic insulation solutions for over 40 years. The Lamatherm fire barrier allows for continuous Lamatherm logoventilation and drainage behind the cladding while providing a hot smoke and fire seal when triggered. Both Lamatherm products are composed of a non-combustible stone mineral wool lamella core, faced on exposed surfaces with a class O fire rated reinforced aluminium foil. This Lamatherm CW-RS system includes products for both horizontal (CW-RSH) and vertical (CW-RSV) solutions.

Lamatherm has been tested and approved by Warrington Fire Research Centre (WFRC) and the barriers are available to suit 30, 60, 90 and 120 minute applications. The horizontal CW-RSH cavity fire barrier has an integral intumescent edge strip which fully closes the ventilated air gap in the event of a fire. To watch this process, click the Lamatherm Reaction Process link below. Lamatherm is suitable for use in cavities widths up to 425mm wide and is able to close a 25mm gap under fire conditions in just 12 seconds. This fire cavity barrier is economical and easy to install. Lamatherm is supplied in 1200mm long strips and can be pre-cut in width to suit advised void size.
