Underfloor Heating Boards Aluminium XPS 16mm

These underfloor heating insulation boards provide a low-profile solution for water-based heating systems, helping deliver fast and even heat distribution across the floor surface. They are well suited to renovation projects and new installations where build-up height needs to be kept to a minimum.

Each board is made from high-density grooved XPS insulation with a fully aluminium-coated top surface. This construction improves heat transfer while keeping the boards lightweight, moisture resistant and easy to handle on site. The grooved design supports straightforward pipe placement and a tidy, consistent installation.

Designed for use with 16mm water-based underfloor heating pipe, the boards are pre-grooved at regular centres to support an efficient layout. The slim profile makes them a practical choice where traditional screed systems may add too much height or weight, while the aluminium layer helps the system respond more quickly once in use.

The boards are suitable for a wide range of domestic and trade projects, including refurbishments, extensions and new-build floors, and can be used beneath various floor finishes when paired with an appropriate overlay system. Available in multiple pack sizes, this product lets you choose the right quantity for smaller rooms or larger installation areas.
