Anyone got a spare length of PIR insulating board, must be 120mm thick, that I could buy? Almost any length or width would do, for now, to get started/practice on (it’s for a narrow cold strip.) (BnQ took my order over the phone, then cancelled it 20mins later, when they realised they didn’t actually have any…)
Thanks!
You will often see quite substantial pieces in skips outside homes having (loft) extensions.
