Expensive machinery; requires skilled operational labor. Chemical and Special Seasoning Planks undergo salt brine dipping. Moisture evaporates uniformly from the inside out. Electrical seasoning uses high-frequency currents. Pros: Minimizes surface cracking on heavy beams. Cons: High operational costs limit commercial use. Common Defects from Faulty Seasoning
Seasoning of timber is the controlled process of removing moisture (water) from freshly cut wood (green timber) to bring it into balance with the surrounding environmental conditions. define the term seasoning of timber
┌── Natural Seasoning (Air Drying) │ ─── Timber Seasoning ─────┼── Kiln Seasoning (Controlled Air) │ └── Chemical/Electrical Seasoning (Specialized) Natural Seasoning (Air Drying) Logs are split into planks. Planks stack in open sheds. Air circulates through horizontal gaps. Low cost; requires zero electrical energy. Cons: Takes several months; highly dependent on weather. Kiln Seasoning (Artificial Drying) Planks enter a sealed chamber. Machinery forces hot, humid air inside. Operators adjust temperature and moisture precisely. Pros: Fast process; kills insects and fungi. Expensive machinery; requires skilled operational labor
If you’ve ever seen a wooden door stick in summer or a floorboard gap open up in winter, you’ve witnessed the effects of unseasoned timber. Electrical seasoning uses high-frequency currents
