Structural Composite Lumber: Laminated Veneer Lumber Laminated veneer lumber (LVL) is produced from veneer and intended for structural framing, where high strength and stiffness are required. Softwoods, such as Douglas-fir and southern pines, are typically used. Some hardwoods are also acceptable. As it is a structural product, only high-quality veneer with high strength and stiffness is acceptable. Unlike plywood, all of …

Treated Birch Plywood meeting the requirements of Euro Class B. Suitable for structural applications. Individual birch veneers are soaked in PW-640 (a fire retardant liquid solution) prior to gluing and pressing. This means that augmented fire retardant performance can be achieved as part of the product’s production process and applies to the entirety of the finished panel. This method of …
