How much vertical movement is acceptable at timber floor joints?
From a professional specification perspective:
Tongue-to-groove clearance should not exceed 0.6mm, which permits some differential vertical movement under load. A T&G tolerance at board edges of about 0.4mm makes a good floor, with standards allowing 0.3-0.6mm. FSA Network floor sanders work within these tolerances to deliver stable, quiet floors.
