The Warmup Tectora UFH System is designed for use within battened or suspended timber floors, including TJI joist constructions. The aluminium diffusion plates fit perfectly across two battens or joists at 400mm centres to create a responsive heating system. The Warmup Tectora UFH Diffusion plates are ideal for timber floors. There are no wet trades involved and consequently no waiting for the installation to dry before the floor can be completed. They are lightweight and easy to install creating a responsive efficient underfloor heating system with an even heat distribution. If you have irregularly spaced joists or battens the Econna System would be better suited. The space between the battens or joists is fitted with rigid insulation leaving a 16mm gap between the top of the insulation layer and the top of the battens or joists. The Warmup Tectora UFH Diffusion plates are then fixed to the top of the battens or joists, supported by the insulation layer. The pipe is then laid before the floor deck is applied.
