has developed several calculators to help guide you through some of the problem areas related to wood flooring.  This calculator is only a guide to provide approximations.  Wood flooring being commercial harvested and manufactured may include both cuts of wood, quarter sawn and plain sawn.  Due to this scenario, there is no real scientific conclusion of expansion or contraction other than approximations.

Gapping is simply a loss of moisture content from the date of installation.  Claims managers can determine current moisture content and gap size by using the current relative humidity.  Wood floor salespersons can use this calculator to help qualify customers acceptance of seasonal gap size prior to installation.  Flooring contractors can project gap size over radiant heat, propose the best flooring specie and width for the application.  

Claims Managers

To use this calculator simply insert the all the required values.  Pick category (Oak, Maple, Cherry), Specie (Red, Hard, Black), sawn (type), flooring width, installation moisture content, board thickness, current Rh condition and this calculator will provide the approximate gap size.
