Does anyone know? I'm getting conflicting advice online and on the phone.
I can't insulate under the floorboards but I would like to prevent heat loss by placing something on top of the floorboards and under the bamboo (uniclic 14mm) that does more than the usual thin foam underlay. We are taking the skirting up and I'm conscious of dust that has blown up onto the edge of carpet (now present) so I would like a product that could be taken right up to the wall edge perhaps taped up slightly to the wall edge I just don't know what that should be!
What did you use please?
