Weyerhaeuser cites Eastern Parallam improvements
Weyerhaeuser upgraded the company's Trus Joist Eastern Parallam PSL beams and columns with a new exterior coating, the company said.
The patent-pending proprietary surface modification technology reduces the rate of moisture absorption during yarding and construction, and delays the effects of ultraviolet (UV) penetration.
"The new coating is uniformly sprayed on to both the narrow edge and wide face of Eastern Parallam PSL at our manufacturing facility and chemically modifies the outside wood surface of the beam or column," said Barry Viviano, engineered lumber products regional manager in New England with Weyerhaeuser. "The protective surface covering resists thickness swell from exposure to both moisture and UV conditions during construction. When combined with our existing end coating, this technology further improves the weatherability performance of the beams and columns."
The coating also provides "an improved appearance on the product,” he said.
Manufactured in Buckhannon, W.Va., Eastern Parallam PSL is available east of the Mississippi River, and is intended for interior use applications, such as open concept floor plans and great rooms.
After sanding the surface, the product can be stained, painted or finished to add long-term beauty to any project. Eastern Parallam PSL products include a limited product warranty for the life of a home.
