Most building codes have allowances for sag, and within those allowances, y ou will see LVL beams sag slightly at 14 feet and longer spans. If you overspan any material, including LVL, you can experience sagging to an extent.Īlways follow the manufacturer’s suggested span requirements, or consult a structural engineer when in doubt. Do LVL Beams Sag?Ī properly sized engineered LVL Beam will have some deflection by nature, but if properly built and installed with crowning up, the deflection makes the beam true and level. LVL is especially a great choice for building houses and buildings with open floor plans due to the more extended manufacturing capabilities.ĭue to the nature of the phenyl-formaldehyde resins used in LVL manufacturing, this lumber is pretty fire-resistant which is another excellent reason to use them in residential construction. LVL beams are a high-quality building product that is an excellent choice for most modern homes. LVL will last longer and stay straighter with the higher upfront cost than the lower-cost option. Expensive – LVL costs approximately twice as much to purchase as standard dimensional lumber. ![]() LVL can delaminate if left exposed to the weather and weaken the structural integrity of the building.
