Rated 4 out of 5 by lightweight underlay this stuff is just like breathable underlay without being breathable, lets hope it lasts longer than breathable. 22 Aug 2014

Rated 5 out of 5 by Up to the test of time I've used this felt several times and found it easy to use strong and durable, but what surprised me the most I used this felt about 8-9 years ago on a job where i just replaced the bottom course of felt three rows of batten etc the customer then phoned me a couple of weeks ago and asked me to do the entire roof as they had a bit of storm damage and a couple of ridge tiles had blown off etc but to y surprise when i stripped the roof the bottom course hadn't even began to deteriorate it was still like brand new which was a shock considering the old bitumen type felt use to start rotting in the gutters after about three years highly recommend to trade or diy 5 Dec 2012
