A structural wood member used at the ridge of a roof to support the ends of roof rafters and transfer roof loads to supports.
LVL Ridge Beam
Laminated veneer lumber is an engineered wood product created by layering dried and graded wood veneers with waterproof adhesive into blocks of material known as billets. Cured in a heated press, LVL is typically available in various thicknesses and widths and is easily worked in the field using conventional construction tools. LVL is also known as structural composite lumber (SCL).
Laminated veneer lumber is manufactured from multiple layers of wood veneer layed-up with the grain parallel to the length of the lumber.
PSL Ridge Beam
Parallel strand lumber (PSL) is a high strength structural composite lumber product manufactured by gluing strands of wood together under pressure. It is a proprietary product marketed under the trade name ParaIlam®.
Parallel strand lumber has voids resulting from the random lay-up of strands. The voids make it possible to treat PSL with preservatives.
Glulam Ridge Beam
Glulam is a stress-rated engineered wood product comprised of wood laminations, or "lams," that are bonded together with strong, waterproof adhesives. Glulam components can be a variety of species, and individual "lams" are typically two inches or less in thickness. ANSI/AITC A190.1 includes requirements for sizes, grade combinations, adhesives, inspection, testing, and certification of structural glued laminated timber products.
