Ventilation Outlets are used to allow moisture to escape from unventilated warm roofs. Moisture can get trapped within the roof during construction, if ventilation is not provided, heat from the sun can cause gases to expand, which in turn can cause blistering and tearing of the roof membrane. The PVC Flange diameter is 285mm and creates a waterproof connection to PVC membranes and liquid plastics.
Area of application
- Breather vents: these are designed to create air circulation above the insulation layer to remove moisture and condensation on the underside of the waterproof layer
- As a renovation vent: for safe repair to old or damaged vents
-
For drying out roofs after construction or renovation to prevent formation mould, rot and surface blisters
Key Features
- Optimum air circulation according to DIN 4108
- Removes penetrating moisture and condensation, to keep the Insulation performance intact.
-
