How long should I allow for on site acclimation of my engineered wood floor before installing?

Engineered hardwood flooring generally does not require the detailed and strict acclimation required for solid wood floors. The thinner the wear layer the less acclimation required.  However, we do recommend that all installers check the temperature and humidity of the environment which the flooring will be installed.  The engineered flooring should be at a moisture content suitable for the environment which it will be installed.  The “Equilibrium Moisture Content Chart” provided by the U.S. Department of Agriculture is available in our installation instructions.  This should be used to determine the proper moisture content of the engineered wood floor.
