What about ground movement then on freshly installed screed and the potential for tiles to crack

Suggestions for screed tolerance over an area?

I havent explained the full story. We're undergoing a rennovation, builder is udnertaking all wiring etc and get electrical signoff but I'm just wanting to check the correct cable is bought. We have to install the spur socket and provide the cable length which the Heatas install will then...

what glue is needed to stick down the mat?

Its being installed by a Heatas installer but I need to arrange for the cabling.

Really? I always thought there was a slight lip, maybe 30mm or so. My parent's house has a lip too but I need to check the height.

What should be the thickness of the glue to stick down the Ditra 25 and generally how thick should tile adhesive be? Trying to understand by FFL height in addition to the tile height.

I need to use some form of heat resistant cable to connect a fan connection kit for a wood burning stove to a spur socket to switch it on/off. What sort of cable should I use? The cable will probably get hot and go under the stove and then out and between the plasterboard dabbed onto the block...

Any comments to my q pls?

I'm assuming it must have really low u values otherwise it would just be another barrier to heat coming through from the screeded floor? Do the majority of builders always install this i.e. its not just a gimmick then? Seems quite expensive at about £220 odd per 30m2 roll.

How high above the current finished floor tile level, should a new front mains door threshold sit, ideally?

Hi - new to this and in the same dilemma. We have about 80m2 of flooring to tile, screeding was done 5 months ago. I wasn't budgeting for this extra cost - is it really recommended to go for the Ditra mat? I've been quoted £220 as the cheapest price for a 30m2 roll. What sort of adhesive do...

Does anyone recommend the use of a Ditra mat for a screeded floor with wet under floor heating? What is the purpose of this mat and is it an unnecessary expense? Also does it lay straight down on top of the floor or need gluing down? If the latter how many mm should the glue be?

http://www.wickes.co.uk/Wickes-Twin-and-Earth-Cable-6-0mm-x-50m-6242YH/p/156256 In the above link, it says max rating 38 Amps for this 6mm cable. Can the same size/thickness of cable have different ampage?

We have a ceramic electric hob and are looking to add a two burner gas hob (possibly a wok burner) to our kitchen. I wont be doing this myself but just interested in the reply to be "in the know". If that gas pipe is not feeding any other gas appliance, would a 15mm copper pipe be more than...

Hi What I meant was, as a general concept, is it ok for any electrical cable to be placed under 100mm Celotex/Kingspan insulation board. The compressive forces of the screed, tiles etc and underfloor heating pipes won't damage it? Our existing ceramic hob I know is on its own circuit so I'm...

Thanks for the quick reply. Just for my lay understanding of circuit designs etc, is it normal for kitchen appliances like oven etc to be wired to their own circuit outside of the kitchen ring main? Also when installing wet underfloor heating, is considered acceptable to have the cable laid...

We are thinking of ordering a new induction hob for our existing kitchen. The manufacturer's web site states that it is 11kw power usage. I would like to know if our existing electrical cable (which is not on the same ring circuit as the rest of the kitchen sockets) will be capable of taking...
