Question

which type of engineered wood product is used for floor/roof beams and headers?
lsl
lvl
osb
cmu

Explanation:

• LSL (Laminated Strand Lumber): Mainly used for studs, trimmer studs, and other structural components where dimensional stability is important.
• LVL (Laminated Veneer Lumber): Has high strength and stiffness. It is commonly used for floor/roof beams, headers, and other load - bearing applications.
• OSB (Oriented Strand Board): Used as sheathing material for walls, roofs, and floors, not typically for beams and headers.
• CMU (Concrete Masonry Unit): A concrete product, not an engineered wood product.

Answer:

LVL
