The Envirotect range consists of the most technologically advanced, vapour permeable, air and vapour control layers (AVCL), a floor cassette membrane (FZT) and high tack sealing tapes – all of which have been designed by Permavent. Envirotect vapour permeable membranes, AVCL layers and high tack sealing tapes are available with a high purity aluminium reflective outer surface. This technology has been tested and certified to have a substantial improvement on the thermal performance of the building when facing a cavity of >20mm. The range is suitable for use in all types of construction methods, in both domestic and commercial projects. Envirotect Walling Membrane Range The recent and significant changes to building regulations Approved Document Part L state new and existing construction projects must achieve higher performance targets and generate up to 31% less CO2 emissions. Adopting a fabric first approach, Envirotect greatly exceeds the requirements of this updated guidance. The Envirotect range has been tested, certified, and futureproofed for any further changes to building control guidance. Permavent Category Director, Craig Fyall, comments: “We’re thrilled to be launching Envirotect after several months of research and development to arrive at this point. Envirotect has been created to address the long overdue need for walling membranes to play a greater part in increasing the thermal efficiency of dwellings, and in turn, reducing our carbon footprint. It provides contractors and specifiers with a modern, technologically advanced solution in a market which requires more manufacturers to invest in innovation.” Permavent has been established as a leading roofing products manufacturer for over 17 years. The Envirotect range joins the hugely successful, A2 fire rated Safeshield walling range which launched just under a year ago to expand Permavent’s membrane offering. As with all Permavent products, Envirotect has been independently tested and certified by a UKAS accredited facility and is UKCA certified.
