Builders and contractors know that long-lasting materials are key to lasting value. With today’s focus on sustainability and performance, treated wood continues to lead the way by combining natural efficiency, renewable sourcing, and decades of proven strength.

ENERGY EFFICIENT FROM THE START
Wood construction materials make up 47% of all industrial materials in the U.S.; yet, require only 4% of the total energy to manufacture.
In contrast, producing aluminum, glass, plastic, cement, or brick can take up to 126 times more energy than manufacturing wood.
That means treated wood starts with a smaller environmental footprint — and keeps saving resources throughout its service life.
BUILT TO LAST—AND LAST
Treated wood extends the life of lumber by protecting it from rot, insects, and decay, reducing the need for replacement and conserving valuable timber resources.
When a deck, fence, or foundation post lasts twice as long, the environmental benefit doubles as well.

CARBON STORAGE THAT KEEPS WORKING
Wood is about 50% carbon by weight and continues to store carbon for the life of the product.
By choosing treated wood, you’re choosing a material that holds carbon longer — keeping it locked away even in demanding outdoor environments.
RENEWABLE AND REUSABLE
At the end of its service life, some treated wood products can provide energy recovery through bioenergy systems — completing the renewable cycle that started in the forest.
That’s sustainability that truly comes full circle.
