Laminated Veneer Lumber (LVL) is an engineered wood product that is manufactured using a closed hot pressing system. It has been proven to show incredible strength & stability. The size of LVL is not limited by log size and is available in both 7FT to 8FT. It is one of the strongest wood-based materials relative to its density. LVL reduces the chances of shrinking, twisting, or bending compared to other relative wood-based doors.
