Knauf Fire-teK WM 910 Wired Mat
Fire-teK® WM 910 is made from Rock Mineral Wool and classified as non-combustible (Euroclass A1) according to EN 13501-1.
When subjected to full scale fire resistance tests to BS 476, a system comprising one layer of 50 mm Fire-teK® WM 910, fixed by using the components and methods detailed on the following pages achieved 15 minutes insulation (I), and retained its integrity (E) for 30 minutes. Testing to BS EN 1366-3 on a single layer of Fire-teK® WM 910 where services penetrate the barrier has also show that a single layer can achieve 15 minutes insulation (I) and 30 minutes integrity (E). A full list of service penetrations is given in the Installation Guide on this page as a Free Download.
A single layer of 50 mm Fire-teK® WM 910 thereby satisfies the criteria laid down in the Building Regulations for cavity barriers, by meeting the minimum requirement of 15 minutes insulation (I) and 30 minutes integrity (E). When subjected to full scale fire resistance tests to BS 476, a system comprising a double layer of 50 mm FireteK® WM 910, fixed by using the components and methods detailed on the following pages, achieved 61 minutes insulation, and retained its integrity for 66 minutes. A double layer of 50 mm Fire-teK® WM 910 thereby satisfies the criteria where fire barriers are required to have EI60 and EI120.
These tests incorporated vertical and horizontal joints between barriers. Fire resistance is effective from either side of the barrier. When tested, the wire side was exposed to the furnace as this is the side most vulnerable to fire. UL Technical Assessment Report Number: 4790228023-1
