Firefly Membrane WP offers certified protection for wall constructions.
The range is suited for use within facade build-ups and other wall constructions, where it will offer weather as well as fire protection while allowing moisture vapour to be vented from the structure. Developed in Australia and used worldwide, it is manufactured in the UK by Lancashire-based TBA Protective Technologies, while it has been certified as Class A2 Non-Combustible under the EN 13501-1 standard Warrington Fire laboratories.
Firefly Membrane WP is supplied in 50 metre-long, 1.25 metre wide rolls with a nominal 0.2mm thickness, woven glass substrate which is aluminised on one side. It is both strong and light to handle, weighing just 14 kg per roll. Although the membrane must be protected from accidental damage during storage and not left exposed to the elements for long periods after installation, it has been tested to withstand wind loadings equivalent to the UK’s most challenging conditions. Installation should be carried out in horizontal bands from the lowest level upwards and fixed to supports at 600mm centres, allowing 150mm overlaps that are secured using Firefly Aluminium Tape. The product is easy to cut on site, allowing it to be folded back into door and window reveals around the building envelope, where it should again be sealed down with the tape, which can also be used to repair small punctures or tears.
