The Volden 1mm XPS foam underlay is designed for use with vinyl click system flooring and LVT planks, providing a smooth and soundproof foundation. Covering 6m², these panels level out uneven surfaces, ensuring a seamless flooring finish. The underlay also acts as an effective sound barrier, minimising noise for a quieter home. Compatible with underfloor heating, it provides added warmth and comfort. At 1mm thick, this underlay offers thermal insulation and soundproofing (18dB) without adding significant height to your floor.
