Lumber of specific dimensions, typically sixteen feet in length with a two-inch nominal thickness and four-inch nominal width, undergoes a chemical process to resist decay from fungal attacks and insect infestations. This treatment enhances the wood’s durability, making it suitable for outdoor construction. It is often stocked at major home improvement retailers.
This treated lumber provides increased longevity for structures exposed to the elements, reducing the need for frequent repairs or replacements. Its resistance to rot and pests makes it ideal for decks, fences, and other outdoor projects, preserving structural integrity over time. The use of pressure-treated wood has significantly extended the lifespan of outdoor constructions compared to untreated lumber, offering economic and environmental benefits by minimizing resource consumption for maintenance and reconstruction.
