Permavent Envirotect membranes are a range of the most technologically advanced vapour permeable, air & vapour control layers (AVCL) and airtight vapour open floor cassettes, walling and construction membranes designed to enhance the thermal performance and physical performance of many wall and construction types. The Envirotect range also features a range of high tack sealing tapes safeguarding a high level of airtightness.
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.
