The Mega Flooring UK 3mm Silver Underlay is designed for homeowners and contractors seeking a durable, high-performance base for floating floor installations, providing superior acoustic dampening and moisture protection. Its core strength lies in its 20kg/m³ density and 70kPa compression resistance, which protects flooring joints from wear; however, its 3mm thickness may not be suitable for leveling deep subfloor imperfections.

This product is designed for acoustic and moisture protection; please verify specific thermal resistance ratings with your underfloor heating manufacturer before installation.
Yes, its moisture resistance makes it an excellent choice for concrete subfloors, provided the concrete is fully cured and dry.
Typically, the integrated moisture barrier (silver side) should face upward toward the flooring, but always check the specific instructions on the packaging.
No, this underlay is specifically designed for floating wood and laminate flooring systems.
The material is lightweight and can be easily trimmed using a standard utility knife and a straight edge.
The subfloor may be too uneven; ensure the subfloor meets flat-surface requirements before laying the underlay.
Check that the underlay is laid edge-to-edge without gaps and that the skirting boards are not pinning the flooring too tightly, which can create sound bridges.
Before installation, ensure the subfloor is clean, dry, and flat. While the 3mm Silver Underlay provides a protective barrier, it is not a replacement for a level subfloor. Lay the underlay with the silver side facing upward or as directed by your flooring manufacturer. Ensure the edges meet perfectly without overlapping, and use a moisture-resistant adhesive tape to seal the seams. This product is compatible with most floating flooring, such as laminate and engineered wood. To maintain, simply avoid excessive moisture during installation and ensure the floor is properly sealed at the perimeter to prevent water ingress.
