There are two primary types of engineered wood composites commonly used in residential construction: oriented strand board and laminated strand lumber, known as OSB and LSL respectively. Oriented strand board is a panel; laminated strand lumber is a structural lumber substitute. Both of these products are made of particles of wood, bound together with an adhesive.
In areas that are prone to natural disasters, beams that hold together rather than shattering are invaluable. It’s not just engineered structural lumber that makes a difference. According to APA – The Engineered Wood Association, sheathing your house with oriented strand board makes your house “two to three times more able to withstand high winds and earthquakes.”
Using advanced technology, Weyerhaeuser manufactures engineered lumber that is consistently straight and strong, and resists bowing, twisting, and shrinking. That means less waste, easier installation, and higher design values for starters; plus fewer callbacks, shorter cycle times, more design flexibility, and lower overall installed cost in the end.
