Has anyone used these boards directly on a screed covered UFH floor?

20mm xps min for 600 centres. Last jacko job I did, studs were 450mm. Used 12mm boards so did as recommended and added studs at 300mm. Time consuming and added timber cost but solid. Would go for this over 12mm hardie anyday.

I used 12mm on 2 floors recently, the first because it was very rough and I needed the extra height, I had a couple boards left so used them today on a small bathroom floor. There’s not one thing nice about them, except there strong as.

Did you use them directly on a screed floor or wooden base?

Do you need to raise the height of the floor?

Do you need to raise the height of the floor?

I do yes, but the floor I had are large 9 x 2 old joists, 50mm insulation between the joists, UFH pipe, then 50mm screed. Ideally would like a strong surface above the screed so it will be hard wearing in the future/
