Can I install my Warmup system directly on top of plywood?
Loose Wire Underfloor Heating
Since wood functions as a natural insulator, you can install your Warmup floor 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.
