XL Underlay

When a subfloor suffers from some minor dips (up to 3mm), XL Underlay can help to solve the problem. It's made from lightweight extruded polystyrene and comes in packs of 10 tiles that are 500mm wide by 1200mm long. It offers exceptional sound and thermal insulation, and when taped together forms an effective moisture barrier.

Our range of underlays and barriers provide support, comfort and enduring protection with products to suit simple and tricky installations. We know how important a great underlay is to achieving a floor that functions naturally well in spaces, and all of our underlays have been designed to meet and exceed industry standards.
