Premium PE Vapour Barrier Underlay 3mm

Product Details

The EcoShield Green Vapour Barrier Underlay – 3mm is a lightweight and practical underlay designed to provide reliable moisture protection and everyday comfort beneath floating engineered wood and laminate floors.

Manufactured from lightweight polyethylene, this underlay features an integral vapour barrier with overlapping edges, helping to prevent moisture migration from subfloors — particularly important when installing over concrete. Its consistent structure helps to compensate for minor subfloor imperfections while also offering modest impact sound reduction and thermal insulation.

With a low tog rating, it is suitable for use with underfloor heating systems, making it a versatile and cost-effective solution for modern homes and apartments.
