Find out moreSuitable for use with various bituminous waterproofing membranes, this CMS Tools TPE Flat Roof Vent has been expertly crafted from thermoplastic rubber (TPE). It lets moisture and water vapour exit from the structure and under the utilised waterproofing membrane.
By letting water escape, it relieves vapour pressure build-up. This reduces blistering and damage. The flat roof vent is incredibly resistant to the effects of low temperatures, meaning it can maintain flexibility in temperatures as low as -40°C (approximately).
