So I have infrared panels mounted on my kitchen and dining room ceiling. We decided to get some porcelain tiles due to their high thermal mass which will help retain the heat produced by the infrared panels. The subfloor is concrete.
We need to raise the level of the floor by about 20mm. My concern is if we use ply, will this interfere with how the heat is stored between the porcelain tiles and the concrete sub floor? Will the plywood “break” the transfer of heat between the 2, therefore leaving the thermal mass of the floor not as good as it would if we were to apply tiles directly to the concrete? If that is the case then what could we use instead of ply that would help to retain the heat?
