Resonate Heatbacker board from Resonate Systems Ltd is a high-performance, overlay board specifically engineered for wet underfloor heating systems beneath tiled floors. Heat backer overlay boards are designed to enable fast and efficient transfer of heat. 

Constructed from a 300kPa XPS (extruded polystyrene) core with glass fibre reinforced cement facing on both sides, this overlay board provides a robust, stable and energy-efficient foundation. It is precision-manufactured with CNC routed grooves to ensure the secure and straightforward placement of UFH pipes, significantly reducing heat loss downwards and directing warmth upwards into the room for optimal energy efficiency. Its low profile design makes it an ideal solution for both new build and refurbishment projects where floor height is a critical consideration.
