Rated 5 out of 5 by Tough as old boots. Very strong and durable membrane. If you want to do a quality job then use this. Easy to work with and will tolerate stainless steel staples to fix to rafters. I have gone over to this from tyvek. Shame there is not a reflective alternative. 23 May 2015
Rated 5 out of 5 by 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
