Hi,
I have just had my ensuite done. I've had electric underfloor heating installed and used Vysal 3mm insulation ( a bit like thin polystyrene) under the heating mat. The installer used flexible adhesive and grout but there is a lot of movement in the tiles, you can see the tiles moving at the edges. The grouting was completed today but it looks like it is already starting to crack.
I mentioned the movement to the installer and he said it can only be the electric heatimg mat wires pushing into the vysal insulation, he has never used it before and thinks this can be the only problem.
Has anyone else used vysal insulation and suffered from any problems.
The bathroom is only 1.2m by about 3.5m and the installer only used 12mm ply as the flooring, I had already taken the old flooring up. I mentioned that 12mm seemed a bit thin at the time and he said 12mm will be fine because it such a small area and my joists are close together.
The movement doesn't seem to be on every tile so I'm not sure if the problem is with the flooring or the fact that he probably didn't install the vysal insulation properly.
