The shape of timber changes due to variations in moisture content (MC). In Scandinavia, the producers of timber normally dry timber to a moisture content of 18% MC. However, after the studs are built into the wall structure, for example, they may become distorted as a result of further drying in the structure.
Humidity has an important impact on forest fires in two major ways. First, long periods of low humidity tend to dry out all forest fuels to a dangerous degree. Even a few days of low humidity can increase the risks of grass and brush fires.
