Our 6mm Low Profile Tile Backer Boards are manufactured from high-quality extruded polystyrene and reinforced with a durable fibreglass mesh on both sides. This construction ensures strength, stability, and long-lasting performance when used as part of an underfloor heating system.
Specially designed to pair with 150w under-tile heating mats, these insulation panels serve two important functions: they provide a waterproof, stable surface for fixing floor or wall tiles, and they act as a thermal barrier to maximise the effectiveness of your heating system. By reducing downward heat loss, they improve energy efficiency and help maintain a comfortable temperature in less time.
Available in both 6mm and 10mm thicknesses, our tile backer boards are easy to cut, handle, and install, making them suitable for a wide variety of domestic and commercial projects. Whether you’re updating a bathroom, kitchen, or utility room, these boards provide a practical, reliable solution for enhancing heating efficiency while ensuring a professional tile finish.
