How much does an 80mm hardwood board shrink or swell with moisture changes?
From a professional specification perspective:
An 80mm wide hardwood board shrinks or swells approximately 0.25mm for each 1% change in moisture content. This means a 3-4% moisture content swing between seasons can produce noticeable gap changes. FSA Network floor sanders use this knowledge to set proper expansion allowances during installation.
