Methods of commonly used to season timber

Air Seasoning:
This is a natural and traditional method where timber is stacked in a way that allows air to circulate freely around each piece. It's a slow process, relying on ambient temperature, humidity, and air movement to gradually remove moisture. While cost-effective and environmentally friendly, it can take months or even years, and the final moisture content is typically higher than kiln-dried timber, usually around 12-18%.

Kiln Seasoning:
This method involves placing timber in a controlled environment (a kiln) where temperature, humidity, and airflow are precisely regulated. Kiln drying is much faster than air seasoning, typically taking days to weeks, and can achieve a lower and more uniform moisture content (often 6-10%), which is ideal for many indoor applications. There are various types of kilns, including conventional kilns (using steam or hot water coils), dehumidification kilns, and vacuum kilns, each offering different advantages in terms of speed, energy efficiency, and timber quality.
