Rhinovent Pro Breathable Membrane 1.5 x 50m

The weather can be unpredictable, but you won't have to worry about that if you use this Rhinovent Pro Breathable Membrane roof tile underlay. It's a composite structure made by laminating a water vapour permeable film in between two layers of non-woven, spunbond polypropylene. This makes it highly flexible, so it's easy to install in a wide range of locations.
The membrane is suitable for use in both warm non-ventilated and cold ventilated roofing systems. The heavyweight membrane makes working in windy conditions a cinch too, as there's no risk of it tearing. It's also weatherproof, giving you peace of mind in knowing that no rain, sleet or snow will permeate through the underlay.
