Tile Backer Insulation Board
Choice of the Professional
Tile Backer Thermal Insulation Boards come in 6mm, 10mm, 20mm, and 30mm thicknesses.
They insulate and resurface walls and floors while delivering a durable, high-performance finish.
Professionals prefer these boards for Underfloor Heating (UFH) systems and Wet Room installations.,/p>
You can tile, plaster, or render over them, making them highly versatile.
On overboarded or plywood subfloors, secure the boards using Cement Board Washers and suitable screws at a maximum of 300mm centers.
When installing on concrete floors, glue the boards down using Flexible Tile Adhesive in accordance with BS 5385-1: 2018.
Enhance UFH Efficiency with Insulation
Living Heat Tile Backer Insulation Boards significantly improve underfloor heating system performance.
Without insulation, UFH warm-up times on concrete floors can be long and inconsistent.
Installing these boards can reduce warm-up times to as little as 10 minutes, delivering faster heating and consistent comfort.
Faster heating reduces running costs, improves reliability, and ensures your UFH system operates efficiently.
The boards also provide additional acoustic insulation, helping reduce floor noise, and add structural support for your tiling or stone installation.
The boards are lightweight yet strong, making them easy to cut, handle, and install.
Their high-density structure ensures they remain flat and stable over time, preventing movement or unevenness in your finished floor or wall surface.
High-Performance Technical Construction
Living Heat Tile Backer Insulation Boards use a high-density extruded polystyrene (XPS) core, engineered to deliver excellent thermal insulation while maintaining exceptional compressive strength.
The closed-cell structure prevents water absorption, making the boards completely waterproof and ideal for wet rooms, bathrooms, and kitchens.
With a strong yet lightweight design, the boards resist deformation under load, providing a stable base for tiles, stone, and floor finishes without flexing or movement.
The insulation layer significantly reduces downward heat loss, directing warmth upwards into the room for faster response times and improved energy efficiency when used with underfloor heating systems.
