Rigid foam seams on roof deck insulation
I have access to affordable foam, but the edges of some of the pieces are slightly deformed or cracked, some look worse than others. None look terrible.
My concern is using one single layer of this foam for an unvented assembly, on top of roof deck, how do I address some of the edge issues. Climate 4C.
Is this a product to stay away from or will it work fine? Price is less than $20 per sheet.
I will try to attach photo.
