The New Warmup Ultralight Board - anygood?

[rila777]

Has anyone used the new 6mm Ultralight Board from warmup. Any opinion, experience with it? Is it worth it. Looking to install it on a Concrete Kitchen floor under El. UFH and porcelain tiles?

Thank you. Did you prime over it before pouring SLC?

I haven't used this yet !! But just read the product description , bit worrying that they describe it as a decoupling membrane , and follow this by saying if screed cracks ,the tiles won't,a decoupling membrane does not stop floors cracking if there is movement upwards or downwards , it just prevents shrinkage and swelling laterally , also they describe it as a great way of cutting costs of running electric underfloor heating!! It would take a few years to gain back just the extra cost of buying these sheets as opposed to the current systems

Here is on the Kitchen Floor. Decided to prime it with Bal All-in-One.

So what now you lay electric cables ? Are they covered in self levelling flexible compound and a decoupling membrane laid on top ??

You lay the dam- membrane and cable after.

Lay UFH Cables, then SLC and then Tiling. Why would I need decoupling membrane?
Ultralite Board should do the decoupling from the substrate - concrete.

I meant the DCM-PRO membrane
