This 1mm high density underlay is designed specifically for LVT flooring without an HDF core (commonly rigid/core vinyl formats). It helps reduce impact noise in the room and provides a strong, supportive base to improve the feel and performance of the finished floor.
Supplied as a roll with 15m² coverage (1m x 15m), it’s a practical option for larger areas and fast fitting. Its high compressive strength makes it suitable for heavier-use spaces where you need a dense, stable underlay rather than a soft foam.
This underlay is intended for floating LVT installations (as applicable to “LVT without HDF core”). Lay it on a clean, level subfloor, butt joins neatly and seal with suitable joining tape. It is suitable for use with underfloor heating when installed within the flooring manufacturer’s system limits.
