Can I install my Warmup system directly on top of plywood?

Since wood functions as a natural insulator, you can install your Warmup underfloor heating system directly on a plywood sub-floor.

We reccomend using Warmup Insulation Boards on a plywood sub-floor to improve performance and maximise the energy-efficiency of the system. Ensure that the sub-floor is smooth, dry and free from dust or objects.
