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 degree of air permeability while remaining watertight. VENT3® AIR has a waterproof layer that prevents water from entering the roof structure. This helps prevent condensation within the roof structure, which can lead to rot, mould, and reduced insulation efficiency.
