What is treated wood commonly used for?

Treated wood is primarily utilized to reduce damage from rot or insects due to the special chemicals that are infused into the wood during the treatment process. These preservatives make the wood resistant to decay and prevent infestations from pests such as termites and other wood-boring insects. This is particularly important for materials used in outdoor applications, such as decks, fences, and building foundations, where exposure to moisture and insect activity is prevalent.

Treating wood with these chemicals extends its lifespan, ensuring that structures remain safe and sound over a longer period. This durability makes treated wood a preferred choice in construction where longevity and resistance to environmental factors are crucial. Although enhancing aesthetic appeal and other characteristics are important considerations in construction, the primary and most crucial function of treated wood revolves around its protective qualities against decay and insect damage.
