Need to get some breatheable sarking felt for a small roof extension. Apparently need this as the tiles i'm using aren't entirely suitable to the pitch we need which is around 22-25 degs.

Is there any one brand that's the best? Seen some Kingspan Nilvent stuff, also Tyvek keeps popping up. I'm assuming its all the same thick waterproof stuff?

Would a wickes/screwfix own brand jobby be any good?

 

we used to use Tyvek on our extension because it said so on the drawing,building inspector and the roofer said not to use tyvek because theres others on the market which are just as good but alot cheaper,.as long as it breathable it will be ok.

 

as above mate, ive been using tyvec for years but theres plenty of other brands out there that do the same job

 

Is it the thick stuff? Seen some 'breatheable' membranes that are like tissue paper lol. I thought it was quite chunky?

 

ive never seen any breathable felt thats like tissue paper, have a look on the screwfix website theres plenty to choose from on there

 

Thats what i wanted to hear

Tyvek mate. Its the best and so easy to work with.


Used to be blue but mostly comes in illuminous green now. Im sure they did that to make us finish the jobs faster, when its on a building you can see it for miles.

 

Cheers for the replies

Struggling to find anywhere in Birmingham that sells Tyvek that I could go and collect tomorrow, so its looking like the stuff out of screwfix will have to do.
