A quick and easy fireproofing cavity barrier for buildings using cladding such as steel-framed modular constructions, pre-fabricated units, and timber-framed houses clad with external brick, block, wood and tiled cladding. Use the Envirograf CV Strip Cavity Barrier with both timber and masonry cavities, protecting cavities from 25mm to 120mm wide.
Self-supporting, the Strip Cavity Barrier expands in fire to form a seal against the external wall for up to 120 minutes, stopping the spread of fire and smoke up a cavity to other parts of a building. This helps prevent further damage from a fire, as well as giving extra time for evacuation. Use around door and window frames, and behind PVC windows for an effective fire-stopping seal.
This flexible cavity barrier strip can be used on curved and profiled surfaces, with a self-adhesive backing for easy fixing. More permanent fixing can then be applied, such as staples and nails. For larger cavities, the Strip Cavity Barrier is supplied with brackets for fixing.
The nature of the cavity barrier ensures airflow around cavities in a building whilst maintaining fire and smoke protection.
More sizes and colours (black, red, white) can be made to order - contact our sales team on 0113 245 5450 for more information.
Peel off paper from double-sided tape. This tape has been developed to ensure good adhesion to most products. The strip can then be permanently fixed with staples, large head nails or screws; fixings approximately 300mm apart.
CV strip for cavities up to 70mm does not require any brackets as the expanding intumescent is self-supporting in the event of a fire. For larger cavity gaps CV30/10 or CV30/15 is supplied with brackets for extra support.
