hi chaps, been doing a roof and it incorporates a flatroof between two pitched roofs, the timber work isn't a problem but the spec says 100mm of cellotex on top of the ply then another skin of ply, then either fiberglass or felt. so what do i stick the insulation stuff down with please?
cheers,
gram.
edit, normally i'd leave all that stuff to guys in the know, but it's a small builder i'm doing the work for and i don't think he knows much about it.
