Electric Underfloor Heating Mat - TilersForums.com

[Spare Tool]

You can lay it over insulation boards Andy

Oh right, interested to see prices difference of normal way to vario then.

Yea thts what I meant haven't actually crumched the numbers but I think in terms of cost to customer, there would really be no massive price difference either way, but I think vairo would work a bit cheaper, if you include labour and materials over all

Can someone explain me purpose of this "uncoupling membrane" ?

My understanding was that on concrete you stick insulation boards with flexible adhesive and then heating mat covered with white flexible adhesive which you stick marble tiles on ?

Is this not correct process for tiling and underfloor heating ?

 

[Flintstone]

That is correct for porcelain tiles. With natural stone they are soft and aren't structurally stable as porcelain, as you will find out when a few probably fall in two!
The uncoupling is basically a layer which separates the tiles from the substrate, it alows some expansion and contraction in the floor without it transferring to the tile. There often made up of about 3 layers so can move independently

 

[Alzak]

Ah I see now I knew that stone tiles are not as hard as ceramic and that was the reason for using flexible tile adhesive so any movement in substrate would not transfer to tiles.


With this uncoupling membrane can you just lay this over heating mat or you need something between heating mat and membrane ? would membrane take the heat from heating mat without any issues ?

 

[Flintstone]

Your best to use self levelling compound over the wires then lay the uncoupling once that's set. Heat is fine

 

[Flintstone]

Are you going to doing this job yourself? There is a thread called 'how best to tile a room' you might fancy having a read at that!

 

[Alzak]

No I would not be doing this myself but I want to make sure this is done right and I would be buying all bits required apart from adhesive.

Any recommendations for this uncoupling mat ?

 

[Flintstone]

My advice would be have a talk with the tiler before buying anything and see what he says /recommends

 

[Alzak]

That would be a problem as installation would be done by my Dad who would be flying in here from continental Europe for 2 weeks, saying this we have different approach to underfloor heating as is mainly (99%) water based systems so that’s why I need help on products from you guys.

He fitted tiles on 100s of floors with underfloor heating but not on wires… and his knowledge on local products is limited as well.

Speak with @Lee@TileTown he's based in the midlands he'll put you right with UFH and antifracture mats, and any other materials you may need.

i agree, variopro would be more expensive, but when you weigh up the down time ect (your time) price doesnt work out that much more.
