Certified lumber product gains record high strength rating

LP Building Products has gained a record high strength rating for its LP SolidStart Laminated Strand Lumber product. According to an LP press release, the product has earned a 1.75E grade from APA – The Engineered Wood Association.

The engineered wood product, based on wood-strand technology, is created through a steam-injection press that cures adhesives for a strong bond and straight board with little swelling. As a result, the lumber product can be made in longer pieces than traditional lumber for faster installation and fewer callbacks, according to the company.

LP says that its environmentally efficient manufacturing process and the use of SFI-certified wood in LP SolidStart LSL gives builders points toward certification with some green building programs, including NAHB Model Green Home Building Guidelines, Green Point Rated, Built Green Built Better and Earth Craft House. The company did not mention the more rigorous LEED certification, which generally requires a more strict certification that than afforded by the SFI program.

According to Melissa Warren, product manager for LP's Engineered Wood Product business
The strength of LP SolidStart LSL means that builders can use this one product throughout the home, including garage door headers and floor beams, to reduce build-up time as well as provide longer spans and greater design flexibility.
