Tournesol Siteworks Boulevard Wood Decking and Siding
Tournesol Siteworks Boulevard Decking is an ecologically responsible deckboard that performs like exotic hardwoods. Made of Tournesol Siteworks’ Boulevard thermally-modified hardwoods (already in use with our site furnishings and as Structural Wood Tiles), the gorgeous decking material has a 25+ year life span (AWPA UC3B), and a Class A flame spread rating (ASTM E84). It is moisture stabilized, splinter, warp and twist resistant, and will naturally weather to a beautiful, rich patina.
Tournesol’s Boulevard wood starts with FSC® certified domestic ash. The lumber is treated at high temperatures (374°F) and with steam in a special kiln in Northern Minnesota. The natural process changes the make-up of the wood, creating a naturally dark-colored lumber with exceptional rot, pest and decay resistance. All lumber is harvested & processed entirely in the U.S.
Boulevard decking is 50% lighter (good for shipping) and far easier to modify and work with on site than South American hardwoods. All Boulevard wood is 100% free of the arsenic, copper, chrome and other hazardous metals present in pressure-treated wood.
Available in 1×4, 1×6, 5/4×4 and 5/4×6 conventional decking planks, as well as in dimensional lumber sizes.
