Question: A builder specifies the use of Laminated Veneer Lumber (LVL) for floor beams in a custom home. What is a key advantage of LVL over solid sawn lumber for this application?

Answer options:

• LVL is significantly more resistant to moisture, making it suitable for exterior foundation use. ✅ LVL typically has a higher strength-to-weight ratio and is more dimensionally stable than solid sawn lumber.
• LVL can be easily cut and notched on-site without any engineering review.
• LVL beams are always less expensive to purchase and install than solid sawn lumber beams of equivalent capacity.

Correct answer: LVL typically has a higher strength-to-weight ratio and is more dimensionally stable than solid sawn lumber.

Explanation: LVL is engineered to have a higher strength-to-weight ratio and superior dimensional stability compared to solid sawn lumber, making it ideal for longer spans and heavier loads with less deflection. It is not inherently moisture-resistant for exterior use, requires engineering for cuts and notches, and can often be more expensive than solid lumber.
