ENVIROGRAF PRODUCT 6: Fire Mortar (Patented)
Description:
An asbestos-free dry mix to which water is added and then mixed like plaster. No shuttering is required. When set, the mortar is load bearing. It can be drilled with wood bits and is easily cut to allow the installation of services. Standard single-bag FM mix available in 25kg bags (FM25).
Use:
Good for fire stopping around building services that pass through floors. Wedge rockwool slabs into the opening, leaving the required depth for the mortar, according to the loading required. It is essential to fit Envirograf® Product 7 (intumescent wraps) around PVC pipes, cables, or steel pipes. For areas over 600x900mm, it is advised to reinforce with 30mm wire mesh, fixed with FB/C straps and support battens. See data sheet for full details.
Performance:
Tested in accordance with BS476 Part 22 (1987). The test report indicated that there was no loss of integrity of the slab itself or insulation for the 240 minutes' duration.
For non-load-bearing areas, a thickness of 25mm will achieve 240 minutes of fire integrity. For load-bearing areas, a thickness of 50mm is appropriate for light loading, 60mm thickness for medium loading, and 70mm or greater thickness for heavy loading.
