*this does not include lead or ladder orders.

The Cromar Vent 3 Light Breathable Membrane – 1.5m x 50m is an exceptional, high-performance breather membrane that works fantastically as a second layer of protection for your roof.

This membrane works seamlessly in fully supported or unsupported slated, tiled, or metal roof systems. It outperforms traditional membranes, delivering unmatched quality. Extensive testing confirms its exceptional moisture vapour permeability and outstanding water resistance.

What happens if water penetrates my tiles on the roof?

This is why it's essential to have a Vent 3 due to its ability to resist water. With the correct installation, any water that does pass the first layer of protection on the roof will hit the membrane, redirecting it into the gutter safely and ensuring no leakage.

How does this product resist water but allow water vapour through?

The outer layer of this product is crafted as a fully functional and exceptional waterproofer, whilst the middle layer is a high-quality, breathable waterproof membrane, allowing water vapour inside the roof space to escape. The final inside layer protects the membrane from abrasion and damage and enhances the overall integrity of the membrane.
