Our PVC & EPDM vents are suitable for installation in built up or asphalt roofing, and allow water vapour to escape from the structure. The vents release vapour pressure, thus avoiding blistering of the membrane.
Our flat roof range of breather vents is available in either EPDM or PVC-u. Vents are normally required when roofing membranes are laid on concrete screeds in which moisture may be retained from the construction process. The vents release vapour pressure, thus avoiding blistering of the membrane.The roofing membrane is dressed over the circular flange of the T-Vent, forming a watertight seal.
