Weyerhaeuser's newest engineered lumber products are made to meet the specific code requirements of West Coast builders, and they'll be showcased at the 2016 PCBC in San Francisco later this month.
The new Trus Joist TimberStrand LSL with Flak Jacket FRT protection and Trus Joist Parallam PSL beams are made with regional requirements in mind, but are suitable for a number of residential and commercial applications.
"The engineered lumber products we're featuring at PCBC provide consistent performance and deliver outstanding results," says Wendy Minichiello, regional director of sales, engineered lumber products, with Weyerhaeuser. "We're showcasing products that meet the specific code requirements for the West Coast to support the needs of builders and remodelers."
The Trus Joist TimberStrand LSL with Flak Jacket FRT protection for rim board applications provides an innovative, code-evaluated, patent-pending fire barrier for rim board. Meant exclusively for commercial and multi-family housing applications (Type III), the boards feature factory-applied coating that meets requirements of section 2303.2 "fire-retardant-treated-wood" of the International Building Code (IBC) and complies with the guidelines of ICC ES AC124.
"Unlike fire retardant treated wood using a pressure process, Flak Jacket FRT protection allows for all the benefits of TimberStrand LSL Rim design properties, including fastener values, with no reductions required," says Minichiello. "This hard-working product alleviates dimensional stability and compatibility challenges while being non-corrosive to fasteners, hangers and connectors."
Meanwhile, the new kiln-dried Parallam PSL beams, headers and columns are engineered to support heavy loads and span long distances, and they are consistently straight and strong.
"We manufacture these beams with a patented microwave process that bonds together long, thin strands of wood," says Minichiello. "The result beams provide consistent performance, deliver excellent connection performance, and resist shrinking, twisting, and bowing."
