Dar timber is commonly treated to enhance its durability and resistance to decay. Treated timber undergoes a process where chemicals are applied to the wood, penetrating the fibers and providing protection against insects, fungi, and moisture. This treatment can significantly extend the lifespan of the timber and make it suitable for various applications in both indoor and outdoor environments. By treating Dar timber, it becomes more resistant to rotting, warping, splitting, or being attacked by wood-boring insects.
