Moisture Content & Wood Movement – Toolbox

Wood is hygroscopic, which means its moisture content (MC) will fluctuate based on the relative humidity (RH) of the surrounding air. As humidity increases, the MC increases, and the wood expands, and as the humidity decreases, MC decreases, and the wood shrinks. This relationship is referred to as equilibrium moisture content (EMC), and can be accurately predicted. Read the full article…
