Electric UFH Partial underfloor heating - Tile Advice

[Ttt1601]

Hello all, just a quick one, what do you lot recom3nd as the cheapest method of keeping floor levels throughout the whole of a down stairs if only the kitchen is having electric ufh. Its over screed and chipboard (which I will be ripping up and replacing with a better substrate). 6mm tile backer board and either dcm, or vairo pro down. But I will need to hold the levels through another 35m2. Any suggestions on how to achieve this in a cost effective t manner ?

Perhaps 6mm insulation on the heating side and 10mm throughout the rest?

Or have a small door strip made out of wood that caters for the difference and save a fortune?

Yea it's either backer board or latex through the rest, need to crunch the numbers on both, it was just a quick one in case someone has a genius idea before I submit a proper quote really

Is it too out of the question to have a small door strip to overcome a small height difference?

Customer wouldn't have it mate, I dont even need to ask to know that, she wants a perfect finish from the front door right through the downstairs in polished porc

Then she has to be willing to pay I guess matey.

Hang on for others to reply somebody might have an idea better than mine lol

There's this too mate: For Sale - Half price Self levelling - http://www.tilersforums.com/threads/half-price-self-levelling.84118/

Not sure if he has it left or what.

I don't think there is any other way if I'm honest was just seeing if someone was a genius and could level floors out in a new and magical way hahah

Cheaper to go 6mm insulation then 10mm insulation than it is to go 6mm insulation then 10mm of leveller everywhere else for sure. Are you doing any uncoupling ?

Yes I will be, but only in a section off the back of the kitchen and into the conseratorybit, as it changes from timber back to screed, the timber to screed joininthekit hen will have the heating over it to work as a decoupled. So was going to fix 6mm board across that whole section, then decouple/ heating system across that. From the kitchen out into the hall is all screed and through into the dining room which is where 12mm of latex or board is needed, But then at the front door it's back to timber for about 1m so will have to do something over that section as well,

Are the requirements for movement joints to be ignored once again?

A domestic kitchen. Decoupled and with silicone joints over the change in substrate should fine no need for full movement joints in this instance in my opinion.
