Ask your QuestionHi...my architect recommended a 22 mm subfloor on top of joists 600....the joiner put a 12.5 instead on top and said that will do.A real wood floor has to go on top.The sbmub floor squeaks. Is this ok?
Asked by Anne on 1st Aug 2022Best Answer
"Not recommended. You architect is correct.
Best contact the finished flooring suppliers.
Or the company fitting it."
"Hi
12.5 mm seem to be extremely thin for a sub floor
I’d of thought the minimum would need to be 18mm with a glued joint"
"If the architect recommended 22mm it must be 22mm and there is no conversation. The 60cm construction is for minimum 22mm boards. I don't understand why they were founded 12.5. In my opinion, a long layer must be applied crosswise so that the floor has sufficient resistance to sagging. Of course, it should be glued to the first layer. As for my eye, "saving". In this case, the joiner is not right. Kind regards,"
