Protect 'felt' roofing product Good as the main brands and just as easy to use. A little expensive given it is not one of the main brands. On low pitch roof I suggest using 2 or 3 layers to stop any capillary action. 19 Apr 2015
Strong membrane Lightweight easy to use. Stong and won't tear unlike some cheaper roofing membranes 9 Nov 2011
best breather membrane Excellent product really tough and definately waterproof as this rubbish summer weather has proved. Wouldn't purchase any other membrane now. 30 Jul 2011
the best breather felt After much research I found this to be the best breather felt that I could get, very tough, doesnt tear easily like others, great properties, this really is much better than tyvek etc.. screwfix were way under other prices and its 1.5 metres so less joins ! 28 Dec 2009
