Vent pipes enable water vapour accumulated under the hydro-insulation to be released without affecting the hydrophobic properties of PVC membranes and thermal insulation properties of the layers.
This enables you to avoid serious damage typical to waterproof roofing with poor ventilation (curling, bulging, dampness of the thermal insulation layer). This could cause partial or complete loss of thermal insulation properties.
Made from PVC characterised by high resistance to UV radiation, ozone, and other atmospheric and chemical agents.
Due to refining additives, the roof vents maintain their flexibility and dimensional stability in a wide temperature range.
The mounting temperature of the vent pipe to the PVC foil is 450 – 520 ˚C.
The use of a higher temperature may cause a damage to the layer protecting against UV, which in turn may lead to the degradation of the vent pipe and unsealing of the roof surface.
