Rated 3 out of 5 by from Visible difference... As soon as this is out of the wrapper you can see *why* it is the price it is. The thickness (or lack of it) has a visible limp to it compared to other sarking I have used. I normally use stainless steel staples to secure the membrane prior to fitting the batterns and they "bruise" the material much more significantly than the more expensive versions. This has cause drip leaks whilst rain stopped play waiting for the tiles to be fitted. The 50m rolls are more difficult to handle across the roof than the 25m option. It is good value though and, carefully installed, will be fit for purpose - You takes yer money and you makes yer choice I guess!
