Rated 5 out of 5 by from Protect vp 400 Great product, easy to lay, easy to cut. A pleasure to work with.

Rated 3 out of 5 by from Membrane This seems like a good membrane, is tough and doesn't tear easily but beads water well and cuts with a Stanley knife nice and easy. Can't comment on longevity yet. My only complaint is that the first roll I bought was grey on the underside but the second is black so it doesn't look uniform and I'm half way through the project, mainly a cosmetic thing but a bit annoying that it's no longer the same as in the picture.

Joint tape

Is there an appropriate tape for taping the joints?
Asked by: DIYDicky

Can this also be used as a vapour barrier on walls as well as underlay on roof?

Asked by: Sparrows
I've used it on my garden room/shed/workshop it's the same as the more expensive Tyvek paper building wrap, it's quite thick, difficult to tear. Same thing as a roof, keep the wind and rain out being waterproof but allows moisture out of the roof/building.

Is this possible

Hi. Looking at installing this on the underside of a fiberglass roof before the celotex, would the moisture side of it still work and how would be the best way to fix it as nail, screws and staples are out of the question?
Asked by: Equinehusband

What is the recommended method for fixing this product to the plywood deck of a warm construction flat roof, while maintaining its integrity, and also what would be the recommended method for sealing overlaps.

Asked by: hobie

Is this a replacement for the felt under roof tiles?

Asked by: Aid1473
Hello Aid1473, Yes, this breathable membrane would be installed under the roof tiles in place of a traditional felt. If you are in any doubt about which membrane is right for your job, we would recommend consulting a roofing professional. Thank you for using Q&A
