Cromar Building ProductsVent 3 Light 1 x 50m Breathable Roofing Underlay, Grey, 1 m

Great item that works as it should. Value for money. I'm very happy with it.

Moisture barrier underneath floorboards

Good brand, well packaged and easy to use. Takes staples well and easy to pull taut without fear of damage.

Used it to provide external cover prior to timber cladding.

First class product would recommend

Breather membrane

Much cheaper than other brands but is no less efficient.

I purchased this membrane to fit to the rafters under the roof as I wanted to stop bits of torching falling down in the loft. I couldn't find a tradesman willing to do the job so I did it myself! The membrane is really good quality and was easy to cut. I used a heavy duty staple gun to attach the membrane to the rafters. It has done the job - when I open the loft hatch I no longer get covered in dust and clumps of torching!
