DAFA roof decking vent

DAFA roof decking vents are used to ensure ventilation through the roofing membrane and can be used for all vapor permeable and impermeable roofing and solid roofing. They can be installed quickly and efficiently in the roofing, from the inside or outside. This is a big advantage, as it is often difficult to retrofit vent outlets from the outside.

DAFA roof decking vents are made of UV-resistant polypropylene/TPE.

Can be installed quickly and efficiently, from the inside or outside, thanks to a ‘snap-lock’ system
