DIY overlay boards for ufh

[EatingSnakes]

Hey guys.

Long time reader, first time poster.

I've got 42mm between my current concrete slab (insulated) and my desired final floor level (tiles)

How do I overlay my pipes?

Is there a thin screed that can be applied over the pipes?

Alternatively I was thinking of making some DIY overlay boards. I got the idea after reading about chipboard overlay boards and thought that I could make overlay boards out of plywood.

I would cut 18mm plywood in strips of 200mm and wedge the 16mm pipes in between each strip.

Each strip would be screwed into the concrete.

The plywood would then be primed and tiles laid directly onto the plywood.

The pipes would have plywood on both sides, concrete underneath and tiles directly above.

The total amount of space that needs underfloor heating and tiling is 4.5 sq m

Any advice would be much appreciated.

Thanks guys

I'm using a manifold anyway.

Here is a plan of my kitchen:

I'm not going to be screeding/tiling where the units go.
I'll batten the space up in the middle and start pouring the mapei renovation screed.

Unless somebody can advice me on pouring a thin sand cement screed with PP fibres?
