Heavy Pipe

Our premium cement-coated XPS boards for retrofit water underfloor heating systems. These overlay boards are made from 300kPa high-density XPS foam which is thermally insulating, lightweight, waterproof, and faced with a reinforced cement coating.

The boards offer a quick and easy solution for the placement of pipework in both domestic and commercial underfloor heating applications. The lightweight, reinforced cement facing provides a robust surface that is ideal for direct bonding of tiles. Many other types of finish, such as engineered wood, carpet, vinyl, etc., can also be used with additional preparation of the panels.

These panels are ideal for installation on solid floors, such as concrete, screed and asphalt floors, as well as suspended timber floors that have been boarded with suitable floor boarding, such as tongue-and-groove planking or chipboard planking.

The panels are easy to cut and install and should be laid with the panel joints staggered in a brick bond style. The routed channels are compatible with flexible low-pressure underfloor heating pipe. The panels are designed for use over existing floors, providing a low-height build-up and insulated floor.

Each cement ocated XPS panel measures 1200 x 600 x 20mm and takes a 15 or 16mm pipe at 150mm pipe spacings. Each are pre-formed with straight runs, return loops and cross runs at one end, and covered with a 3mm layer of concrete.

The panels can be laid onto any existing, level flooring and should be fixed securely using standard tile adhesive.

PLEASE NOTE: due to fragility this product has to be shipped by pallet. 

Flooring Advice:

Laminate/Engineered wood
Cover boards with a 3mm breathable underlay then float the floor planks straight over. Use a floor sensor to stop overheating and damage to the wood.

Carpet/Vinyl
Prime the surface and pipe runs, then cover with a self leveller between 5-10mm. Alternatively, cover with thin wooden sheets not exceeding 6mm. The carpet & underlay combined should not exceed 2tog rating.

Tile/Stone
Prime the surface and pipe runs then tile directly onto the boards using an S2 rated Flexible Tile Adhesive.

Maximum pipe length:

• 20mm panel = 100m
