Thanks Lou.Great thread - thanks for keeping us updated. Please show us all the finished job!
Any suggestions as to what layers I need from the Wedi upwards (for a heated floor)?
I think the Wedi will serve as insulation and as a decoupling membrane from the subfloor. But I don't understand why they advise their 600mm glass-fibre reinforcement on floor panels. Presumably to further limit any movement...? But do I still need to use reinforcement if I am laying a heated floor - won't ditra-heat, or a self-adhesive heating mat, do the same thing?
And would you just stick down a self-adhesive heated mat (like warm-on), and set it in self-leveller, prior to tile... Or thinset down some ditra-heat, then self-leveller, then tile?
So my questions - (1) do I still need to use 600mm fibreglass reinforcement if I am laying a heated floor; and (2) would you advise a self-adhesive mat, or ditra-heat, on the cementacious face of the wedi?
Thank you..!
