Screed systems are traditionally used in new build projects. Screed systems require the floor heating pipes to be fixed to the subfloor insulation layer prior to being encased in a layer of concrete or chemical screed. The warm water in the pipes heat up the concrete (screed) which acts as a thermal store and radiates it into the living space. This process can take a few hours to both heat up and cool down and is less controllable.
Wundatherm boards are bonded on top of the rooms existing concrete or wooden floors making them ideal for renovations.
Wundatherm is a modular system of lightweight high density eps boards with pre routed channels that secure the floor heating pipe in place. The boards are covered with Aluminium foil that quickly and efficiently spreads the heat from the pipes evenly over the surface of the Wundatherm board.
The final floor finish is placed directly on top of the Wundatherm board which ensures fast transition of heat from board to living space (rapid response). Because Wundatherm doesn’t rely on a thermal mass to transmit the heat, it warms up and cools down very quickly, about as fast as radiators, this makes Wundatherm systems very controllable.
