NEVER ABOVE 18%*
Do not install WindsorONE Trim Boards with moisture content higher than 18%, and ensure this by use of a moisture meter to gauge moisture content levels for all installations. WindsorONE Trim Boards are shipped with an average moisture content of 10% to 14%. Storing material in humid environments or near concrete or dirt will increase the moisture content. Installing material in unheated or unconditioned environments during wet winter or summer months will also increase moisture content, resulting in expansion and potential joint failure. Condition the Trim Board material on the jobsite by allowing it to adjust to an equilibrium moisture condition. Learn more at www.windsorone.com/moisturecontrol
*Note for INTERIOR MOISTURE CONTENT: Make sure you properly acclimate WindsorONE before interior installation and do not install when moisture content is over 8%.
