Discover unmatched stability and long-lasting performance with our 5mm XPS Black Underlay, expertly engineered to support laminate and engineered wood flooring. Designed to smooth out minor subfloor imperfections, this high-density underlay creates a level, secure base that enhances the durability and lifespan of your floor installation. The 5mm thickness offers excellent compression resistance, helping to prevent movement and maintain a firm, stable feel underfoot. With effective impact sound reduction, it significantly minimises noise transfer, creating a quieter and more comfortable living space—ideal for busy households and multi-storey homes. This underlay also delivers strong thermal resistance with an efficient TOG rating, helping to retain heat and improve overall energy efficiency. By reducing heat loss through the floor, it contributes to a warmer space and potential energy savings throughout the year. Lightweight yet robust, the XPS construction ensures easy handling and quick installation without compromising on performance. Offering outstanding value, this underlay combines strength, comfort, and insulation in one reliable solution. Upgrade your flooring with confidence using the 5mm XPS Black Underlay—a smart, practical choice designed to deliver superior support, enhanced comfort, and dependable long-term performance.
