which way to tile concrete floor with ufh - Tile Advice

[crows foot]

hello there.

i'd like to get my lounge diner and hall tiled with ufh

for some reason the concrete floor is quite high to the patio doors and back door so i don't really have room for insulation board, i would like to use a product called ditra matting as the concrete floor has some cracks and also has a high point of 15mm

is the best way to lay the ufh with ditra on top then adhesive and tile or do i need to adhere the ufh and or the ditra matting?

some advise would be much appreciated

just to say i will not be carrying the work out but will be asking for quotes, thats to put your mind at ease :smilewinkgrin:

regards mr foot

Schluter do say that ufh can be fixed on top of Ditra....

you can get insulation boards as thin as 4mm. (warmup) with a concrete floor you really would need some form of insulation.

Yeah insulation boards are definitely recommended here, you dont want to be loosing a load of your heat downwards

This is the normal make we always say for our products.

Elektra MD160 (160w/m2) or MD200 (200w/m2) Underfloor Heating Mat.
Best method for installing onto insulation boards where the floor finish is to be Tiles / Slate / Stone / Marble / Porcelain etc.
6mm insulation board will need an overall extra spare depth of 8mm: 6mm board with 2mm powdered flexible tile adhesive under the boards to fix.
After the Electric Mats are installed, a powdered flexible self-levelling compound is used to cover the underfloor heating to cover. (5mm good)
A powdered flexible tile adhesive is used to fix the floor finish. (at x mm + tile depth)

Warm regards,

Hi Keith, i have a floor with UFH coming up soon. I was going to use a 6mm Marmox or Wedi type board as the insulation. Is this method not essential as i'm wondering if there is a cheaper option i could use ie: Ekoboard.

The current substrate is concrete and sand/cement, because of height restrictions the boards have to be 6mm maximum.

Thank you mate
Toby

Good morning,
Yes, on concrete, screed etc, Ekoboards are the way to go.
Same installation as construction boards.
We stock both types of boards in the 6mm, as well as 10mm and 20mm in both. By far lots more Ekoboard stocked & sold.
Small technical web site for the Ekoboards - ekoboard co uk etc.

Warm regards, Keith
