I have a guy selling foiled insulation board 80mm. I cant seem to find what it is to make sure it has the same U value as kingspan.
The foil is plane with reinforced thin thread through it and the foam centre is pink coloured. There is no product markings but he tells me its sheffield insulation but I cant find it. Anyone got any ideas.
