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?

Here is what it looks like

I have used the ultralight boar, top product 100%

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 ??

 

[demi34]

You lay the dam- membrane and cable after.

 

[rila777]

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

 

[demi34]

I meant the DCM-PRO membrane

 

[rila777]

I am just running the ProWire Lose wire warmup
system directly on the boards

 

[demi34]

Yes that’s fine but make sure you put self levelling to cover up the wire

So what stops the movement from the underfloor heating into the tiles above the cables ??? As they heat up and cool down ?? Think about it ??

Flexible SLC and Adhesive.

You have sorted the first movement problem

Flexible SLC and Adhesive.

Suppose we will find out in 10 years

What would be your suggestion to resolve the UFH movement ?

I would still put a decoupling mat directly under any tiles I lay , that have ufh underneath them !! Why do so much work and not be sure !!
