TF: Large format stone on UFH timber suspended floor- a job for Ditra matting?
Hi all,
I'm doing a barn conversion at the moment and the ground floor requires 50 sq.m of indian mint sandstone. The floor to be tiled consists of about two-thirds timber suspended floor with wet UFH under a 22mm moisture resistant chipboard deck, and the other third is a floating chipboard deck over an existing concrete slab, also with UFH. Both floors are very sound but obviously have a little flex, like any floor of this type. The stone is variable thickness from 20mm to 40mm. A friend of mine already has this stone on his suspended floor, and he used dabs of adhesive to reduce the amount required- however I am told this is unsuitable for UFH because the air gaps would stop the heat getting through from the sub-floor, which sounds reasonable. So, am I looking at using a (very expensive) thick bed of flexible adhesive? The Schluter Ditra matting has been recommended to me as the ultimate solution, but is bloody expensive over 50sq.m!
Can anyone confirm or deny that a solid bed of flexible adhesive would be the best solution? It's really gonna blow the budget if I have to use it, but if it's the only solution then I guess I have no choice.
All comments/feedback gratefully received, I could really use some advice on this!
Many thanks,
Rob
