Vapour Barrier 3mm Foam Underlay
Protect Your Floors from Moisture Damage
Our Vapour Barrier 3mm Foam Underlay is the perfect solution for protecting your floors from moisture damage. This specialist underlay provides a moisture barrier that prevents damp from rising up through the subfloor. Its built-in vapour barrier and excellent resistance to mould and bacteria ensure your floors stay looking great for years to come.
Made from 100% recyclable polyethylene foam, the Vapour Barrier underlay is an eco-friendly choice for your home. At just 3mm thick, it adds a subtle layer of cushioning that makes laminate and wood floors more comfortable underfoot. It also helps absorb sound, reducing impact noise levels by up to 20dB.
The lightweight foam is easy to install in any room, and its dust-free material means minimal mess. Once in place, it offers the ideal level of support to guard against wear, absorbing the impact from heavy foot traffic and furniture. This protects your flooring investment by preventing dents and damage over time.
For affordable moisture protection and sound insulation that's kind to the environment, choose our specialist Vapour Barrier underlay. Protect your floors in style with this high-performance underlay.

Fitted this under our new washing machine and around the utility room. The vapour barrier side is dead easy to identify and it went down without any fuss. Good value for a basic underlay.

Fitted this under some new laminate in the spare room. The vapour barrier seems solid and it was easy to cut and lay. No complaints.
