How much does wood expand and contract?
Correspondingly, how does wood expand and contract?
Wood expands and contracts with changes in the surrounding humidity and to a lesser degree the temperature. More humid air will cause wood to expand; drier air will cause wood to contract. This movement cannot be stopped. You can learn what to expect and techniques to cope with the movement.
Also know, how much does wood expand with moisture?
Wood dries to an average moisture content of between 4 and 11 percent, depending on the area of the country, but it never really comes to rest! The amount of bound water in the wood continually changes with the amount of moisture in the surrounding atmosphere.
No, temperature changes don't do anything to wood directly. Wood reacts to moisture in the air and the wood itself. So during cold months, wood typically stays the same size. Water cannot evaporate into cold air as easily as warm air.
