Boulevard Decking

Boulevard Decking is an ecologically responsible deckboard that performs like exotic hardwoods. Made of Tournesol Siteworks’ Boulevard Thermally-Modified hardwood (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 ash. The lumber is treated at high temperatures (374°F) and with steam in a special kiln. 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 1x4, 1x6, 5/4x4, and 5/4x6 conventional decking planks, as well as in dimensional lumber sizes.

The Thermal-Modification Process

Phase 1:  Temperature Increase and Kiln Drying
The air temperature in the kiln is raised at a rapid speed using heat and steam to a level of around 212°F, the wood temperature follows at a similar level. Thereafter, the temperature is increased steadily to 260°F and drying takes place. Steam is used as a vapor membrane to prevent cracking of the wood. The steam also facilitates chemical changes taking place in the wood. At the end of this phase, the moisture content is reduced to almost zero.

Phase 2:  Intensive Heat Treatment
During the intensive heat treatment phase, the air and wood temperature is increased to a level of 401°F.  When the target level is reached, the temperature remains constant for 2 – 3 hours. Steam is used to prevent the wood from burning and cracking, and it also continues to influence the chemical changes taking place in the wood.

Phase 3:  Cooling and Moisture Conditioning
The temperature is reduced using water spray systems. Conditioning and re-moisturizing takes place to bring the wood moisture content to approximately 6%.  Low moisture level and altered cell structure provide long-term dimensional stability and resistance to warp, twist, and other wood movement.

End-matching

 Reduce the amount of waste, scrap and labor by using Tournesol’s Boulevard decking with end matching. The end match allows boards to meet between joists, eliminating cutting the length. Each board is fitted with both a male and a female end. Specify end-match by adding -EM to the part number.
