Cromar Vent 3 Breathable Roof Underlay can be used in cold and warm roof applications. At 75m² coverage, you can ensure you have the product needed to help protect a pitched roof or surface.

The Cromar breathable membrane range offers major benefits over traditional roof underlays, with strength and durability being two of many key features. Breathable membrane by Cromar, unlike traditional roof underlays, requires no ventilation. Meaning protection of your pitched roof or other surfaces can ensure vapour escapes with success.
