What fixing methods are recommended for fixing Celotex to the roof deck on a flat warm roof?
I guess the vapour barrier will be stuck down with an adhesive on the OSB.
The Celotex on top of that. I've seen some helical fixings, but I'm a little unsure about those and I don't see a lot of information around.
Would a suitable roofing adhesive work or is the only way mechanical?
I get a feeling in my water that a decent adhesive over the surface area will give a good defence against uplift from wind... though wonder about how that would fair against thermal movement.
I'm probably going for the two-layer Wickes underlay and capfelt on top of that... also probably the topic of more questions when I've gotten on top of this detail
