treated wood
Pressure-infused lumber
Treated wood is lumber that has been chemically processed to resist rot, insects, and moisture.
Pressure-treated wood, the most common type, has preservatives forced deep into the grain: The deck is built from treated wood.
It's standard for outdoor construction—fences, decks, playground equipment—but shouldn't be burned, as the chemicals produce toxic fumes.
