Quebec-based Lamco Forest Products has introduced LFL—an engineered lumber made from short lengths of slow-growing black spruce. The short culls are bound together with double tongue-and-groove edge joints and structural finger joints.

It’s reportedly lighter than LVL, but has a superior fire rating.
