22mm No More Ply - Tile Advice

[ajkzrr]

Hi,

I'm installing aluminum spreader plate under floor heating between joists (1930s house), and I'm thinking of using 22mm No More Ply over the joists, then tiles.

What do you think about this setup? Is that better than ply plus a thinner backer board? Will I still get enough heat transfer through?

Thanks in advance!

You will get better heat transfer through nmp than ply . I don't know if they still do it but knauff brio I was told by knauff thermally transparent . I think this means good conductivity

Marmox used to do a board designed to go on top of UFH, different to the foam insulation board they do obviously.

The 22mm no more ply is the perfect way to deal with these ufh systems.
