Can you put plywood over OSB?
OSB (Oriented Strand Board) Subflooring 3/4″ Thick Solid Wood Flooring can be installed directly over 3/4″ thick OSB subfloor. … If the OSB sub flooring flexes up and down when walked on then you should add an additional layer of 3/8″ or 1/2″ thick plywood underlayment glued and screwed down to add stability.
Is OSB good underlayment?
An OSB board absorbs moisture less readily than plywood, and the main problem with an OSB subfloor getting wet is that the seams of the individual sheets can swell. This swelling, although undesirable and to be avoided, is virtually unnoticeable under a laminate floor unless it is very pronounced.
How thick should floor OSB be?
the subfloors need to be thicker. For joist spacing of more than 16 inches up to 19.2 inches on center, the minimum thickness for both plywood and OSB is 3/4 inch. For joists spaced more than 19.2 inches on center, the minimum thickness for plywood is 7/8 inch and for OSB, 1 inch.
Why is OSB so expensive 2020?
