Insulation of ceramic floor tiles

[AnonymousImport]

I am about to set tiles on a concrete slab. Is there any way to insulate my floor?

The difficulty would be height. How much do you have?
May I recommend: If it is a largish - well used area such as a kitchen that you install underfloor heating.
It will not (as much as they would love you to believe) heat the room very well - but it will take the chill off the floor... so it is nice to walk in barefoot.

A slightly cheaper option is to lay marine plywood - that may insulate against the cold concrete a little... as wood is a good insulator.

Screw 10mm marine ply every 6in to prevent movement in future.

Thanks a lot. We are taking about a 260 sqfeet livingroom area. The plywood should be layed on the concrete and the tiles on top of the wood? Or would I need additional mortar before I can lay the tile? Wood backerboard be an option?

I watched tilers spread tile adhesive straight onto plywood. Then waited an hour and finished job by coloured grout to joints. This was walkable with care but best left for a day. As floor tiles so expensive and job so quick you might consider letting them do the cutting and placing.
Tiler will follow profile of floor as uses consistent spreader. Would suggest you check if concrete floor has slope or is very uneven. There are latex compounds you can use to correct small errors and cement based compounds for bigger thicknesses.
