Expansion and contraction of your flooring system is a given. Because they are manufactured from different materials or different kinds of the same material, your flooring and substrate will expand and contract at different rates.

While you should always adhere to the manufacturer’s installation instructions, there are some general guidelines provided by the NWFA that apply to most subflooring installations. There are a number of subflooring options available and you can speak with your design professional to find one that suits your climate, needs and budget.

While this is not a definitive guide to hardwood installation over OSB panels, there are some important points to ponder.
