What is the main purpose of using treated wood in construction?

The main purpose of using treated wood in construction is to extend the lifespan of wood materials and prevent damage from insects and rot. Treated wood undergoes a process where preservatives are infused into the wood, making it more resistant to various environmental factors that can lead to deterioration. This includes protection against moisture, which can cause rot, and resistance to pests such as termites and wood-boring beetles that can compromise the structural integrity of wood.

Using treated wood is especially important in areas exposed to the elements, such as outdoor decking, fence posts, and garden structures, where untreated wood would be more susceptible to damage over time. The economic benefits of using treated wood are significant, as it reduces the need for frequent replacements, maintenance, and repairs, ultimately leading to safer and more durable construction.
