Floating Floor Underfloor Heating

Floating floor section drawing for Profoil.

Profoil™ Floating Floor Panels are manufactured to meet the client’s individual project requirements and hence provide a totally flexible, bespoke solution that enables specific design and performance criteria to be achieved.

A polythene vapour barrier is laid on top of the concrete slab and the panels are then laid across the whole area. The floor finish, tongued & grooved chipboard or wood strip flooring, is then laid directly over the panels, leaving a small expansion gap around the perimeter of the room. In areas of heavy traffic, timber supports should be placed directly beneath the floor joints.
