Luvanto Barrier Plus Underlay (GB2) - 1000 x 15000 x 3mm

Give your flooring reliable protection from the subfloor upwards with the QA Luvanto Barrier Plus Underlay. Designed with vapour barriers on both sides and a double overlap, this underlay provides enhanced protection against rising moisture. It helps create a dry, protected base beneath your flooring while helping to guard against moisture-related issues such as damp, fungi and mould.

Enhanced Moisture Protection

The dual vapour barriers provide an additional level of protection against moisture coming up from the subfloor. Combined with the double overlap, the design helps create a more secure moisture-resistant layer when installed correctly, making it a practical choice for flooring projects where moisture protection is a key consideration.

Cushioned Support for Your Flooring

Barrier Plus does more than provide moisture protection. Its cushioned construction helps absorb everyday impact and reduce wear, providing a supportive layer beneath your flooring. It is designed for medium-traffic areas and is suitable for use with laminate and engineered wood flooring.

Lightweight and Easy to Handle

Despite its protective performance, the Luvanto Barrier Plus Underlay is lightweight and easy to work with. It can be lifted, moved and positioned with minimal effort, helping to make installation quicker and more convenient. Made from 100% recyclable PE foam, it also offers a practical option for those looking for a more sustainable flooring solution.

Features and Benefits

The Luvanto Barrier Plus Underlay combines dual-sided moisture protection with cushioning and impact support.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
