Heating that's part of the floor
Warmboard takes a different approach to hydronic floor heating. The pipe sits in channels routed into the panel, and the panel’s aluminium face spreads the heat across the floor.
There’s no screed layer to pour and wait on: the floor covering goes over the panels.
In our experience, with timber glued directly to Warmboard, the floor surface feels warm within 20 to 30 minutes of the heating starting. That’s the floor surface, not the whole room reaching temperature.
