Anybody know if there is a difference between PIR boards made for walls & the stuff made for roofs?
My local builders merchant sells Xtrathem for cavity walls which will work well for insulating between the rafters of my loft.
Just want to find out if there is any real difference between that & the stuff made for the job (they sell the loft stuff in large sheets).
Both are the Thin-R XT range. The cavity stuff is t&g & will be easier to handle & get up there.
