Description
Polyfoam underlay can be used on any sub-floor that is level and dry such as floorboards, chipboard, hardboard and plywood. If it is to be used on a concrete sub-floor then a damp proof membrane (DPM) will also have to be used. This can either be in the form of sheets or a 2 part damp proof membrane which is a liquid resin that sets to seal the concrete subfloor. Alternatvely, a combination underlay that incorporates an integrated vapour barrier could be used. Polyfoam underlay comes in rolls of 1m x 15m
