Should You Handle or Store LVL Beams Differently?
LVL beams are similar to traditional wood beams in that you should keep them wrapped to protect from the weather and use stickers to separate bundles. To preserve the LVL beams from water damage, we recommend that you store the LVL material at least 12 inches off the ground.
What is LVL in wood?
LVL stands for Laminated Veneer Lumber and is similar to plywood in appearance. The difference is that plywood changes the grain’s direction with each layer, and LVL keeps the grain direction the same. LVL is typically made in a factory, straighter, more uniform, and stronger than traditional milled lumber. An LVL engineering process uses multiple layers of thin wood assembled with adhesives.

Can you drill holes in LVL beams?
You can, however, drill holes in the beam at predetermined zones where horizontal holes are permitted for passage of wires and conduit. You should not have vertical holes unless the beam width is 3 1/2 inches or more. Always consult with an engineer or architect before cutting or drilling any holes in an LVL beam.
Is LVL lumber waterproof?
A drawback in LVL is it is more susceptible to water damage and rot if it gets wet than traditional lumber. The adhesive on many LVL beams is waterproof, but that glue will start to delaminate with repeated water infiltration, weakening the LVL beam. LVL work for interior and dry location applications.

How to determine LVL span size?
Use an LVL span size chart for a single floor by finding the size range of LVL beams you are using and the space between the floor's support columns. Then match these figures with the appropriate maximum span size. For example, if you are using an LVL beam with two plies of 16 inches or three plies of 14 inches with the columns spaced 14 feet from one another, the maximum span size is 36 feet. This span size only applies to single floors; floors supporting additional stories or roofs require sturdier construction and use different LVL span size charts.
What factors affect LVL beam size?
Keep in mind that values given by an LVL span size chart are approximate. Numerous factors - such as the area's humidity, weather conditions and even average snowfall - can have a large effect on an LVL beam's maximum span size.
What is a single floor LVL?
The simplest type of LVL-based floor is a single floor that does not support an additional load. Common single floors include second-story floors or floors over a basement. Because these floors support the lightest loads, they require the fewest support columns and the smallest LVL beams.
