Flameblok

FlameBlok is the only 100 per cent post consumer recycled PVC-U cavity closer that offers up to 90 minutes fire-rated performance, along with being a window receptor and thermal break, all in one product. This saves labour, creates a template for wall construction and ensures a safer, more thermally efficient building.

Like other Cavalok cavity closer products, the FlameBlok range is unique in being manufactured from 100% post-consumer recycled PVC-U, often from old windows, helping specifiers and developers meet sustainable sourcing targets.

The architects had specified a fire rated cavity closer on Diglis Water to meet the stringent safety requirements set out by Taylor Wimpey (Bryant Homes) West Midlands.

Fire-rated cavity closers are an essential part of helping improve the safety for building occupants during a fire. This is because cavity walls provide a continuous hidden path around the building, potentially spreading fire from one part of the structure to another without being detected.

Working to the architect’s brief, MDS Architectural Fabrications Ltd, recommended FlameBlok because it provides a 90 minutes fire-rated performance, eliminating the need for further cavity barriers, as well as creating a former for the bricklayers.

FlameBlok is unique in having a continuous strip of fire protection, which includes an innovative corner design, to provide fire performance all the way around a window in line with Building Regulations Part B guidance.

The traditional brick and block 100mm cavity wall at Diglis Water was fully filled with blown mineral wool insulation to maximise the energy efficiency of the building. This cavity insulation was complemented by the FlameBlok closer, providing a vital thermal bridge around window and door junctions.

FlameBlok was supplied by Cavalok approved fabricator MDS Architectural Fabrications Ltd, based in Solihull, West Midlands.

John Pardoe, Managing Director of MDS, comments: “Our customers have been delighted with the new FlameBlok range from Cavalok because it combines 90-minutes fire rated cavity barrier and cavity closer in one. Innovation such as this gives our business a real advantage, helping us to win high specification contracts like Diglis Water.”
