Looking for an air permeable breathable roofing membrane that will not let you down when the weather is wet.

Vent3 Air has the ability to allow air to pass through while blocking the passage of water. It is specially designed to have a high level of air permeability while remaining watertight.

Vent3 Air has a waterproof layer that prevents water from entering the roof structure. This also helps prevent condensation which can lead to rot, mould and reduced insulation efficiency. 

Cromar have been working tirelessly over the last 2 years or so to develop this breather membrane that is more air permeable than others on the market and up to 10 x times more waterproof.
