XPS Underlay Insulation for Laminate & Wood 3mm

This XPS underlay is designed to sit beneath laminate and wood flooring, helping to improve comfort and reduce the sound of footfall. It adds a useful insulating layer to help keep rooms warmer, while also supporting a more even finish.

Made from extruded polystyrene (XPS) foam, it is lightweight to handle and quick to install. The closed-cell structure is non-absorbing and mould resistant, making it a practical choice for busy homes and everyday living spaces.

Use it to help bridge small subfloor imperfections and to support joints for a more stable floor feel. It’s ideal for refurbishments and new installations where you want a cleaner lay and a more comfortable surface underfoot.

Each pack contains multiple boards that can be laid out and cut to suit your room layout before installing your chosen floor covering on top. Board colour may vary between batches, but performance and quality remain the same.

Choose the pack size that matches the area you need to cover, including a sample option if you’d like to check suitability before ordering larger quantities.
