Do you use or recommend some sort of "uncoupling" membrane (like Schluter Ditra) if one is installing tile planks over the factory wood subfloor, to help prevent future tile cracking due to normal subfloor movement while driving or leveling? https://www.schluter.com/schluter-us...TRA-XL/p/DITRA
My stock tile floors have no uncoupling membrane under them and I have already had some tiles come loose and a couple have some cracks (which have been now been repaired/replaced).
The factory install is just standard porcelain tile glued (thinset or adhesive - I'm not sure what they used at the factory) directly to the particle board subfloor. It appears to have worked for 15 years (although I'm not the original owner) so perhaps the factory knew what they were doing.
I would like to stay with tile - but I want the "plank" style (12 x 36) which would be more prone to cracking is the subfloor moves/twists a little then the factory 12x12 tiles.
I don't mind the extra cost/labor to put down a uncoupling membrane if it will improve the longevity of the job. What do you think?
