XPS Foam Floor Underlay for Laminate and Wood 5mm Loose Lay

This premium XPS foam underlay is designed for use beneath laminate and wood flooring, helping to improve comfort and performance in everyday living spaces. It adds an insulating layer to help keep floors feeling warmer, and supports a quieter room by reducing the transfer of impact noise through the floor.

Made from extruded polystyrene, the underlay is lightweight and easy to handle during installation. The closed-cell construction is moisture resistant and durable, helping it stay stable over time while offering support across board joints and helping to level minor unevenness in the subfloor.

Ideal for refresh projects and new installations alike, it suits most common indoor subfloors where a loose-lay underlay is required before fitting a floating laminate or engineered wood floor. It can also be a practical choice where you want to help reduce the feel of cold coming up through the floor.

Choose the pack size that matches the area you need to cover, from single packs through to larger multi-packs. A small sample option is available if you would like to check the feel and thickness before ordering full packs.
