Predicting the Air-Drying Time for Lumber Using the Air-Drying Estimator Spreadsheet

Lumber is often air-dried for months prior to being kiln dried. The air-drying yard manager must decide when to stop air-drying and move the lumber to the dry kiln. The Air-Drying Estimator Excel spreadsheet is based on previous air-drying of lumber research. The intent of the Air-Drying Estimator is to help the air-drying yard manager…

Calculating the Equilibrium Moisture Content

The moisture content of wood in an environment held at the constant conditions of temperature and relative humidity will come to an equilibrium with its surroundings.  The air temperature and relative humidity will determine the equilibrium moisture content (EMC) conditions, and the moisture content of wood in that environment will approach the EMC of the…

The Equilibrium Moisture Content of Wood in Exterior Locations in the United States: An Update

Wood responds to atmospheric moisture in a predictable manner.  If the relative humidity and temperature of the air are known, we can determine the equilibrium moisture content of that air, or EMC.  Knowledge of the EMC is useful in estimating how fast lumber on an air drying yard will dry; how long it will take…
