LVL beams are long pieces of lumber that are typically used for windows and doorways that are wide. Use an extremely strong glue when working with wooden LVL beams, or your wooden structures will fall apart if you don’t.

What glue is used for LVL?
In the production of laminated veneer lumber (LVL), phenol-based adhesives like PH and PRF are commonly used to adhere the veneer’s layers together. A visible adhesive seam is left behind when these adhesives are cured at high temperatures.
Can you screw into LVL beam?
If this deflection isn’t properly considered, it could put a lot of stress on the supporting equipment or piping. For LVL beams with a 3-1/2-inch-wide beam, avoid drilling vertical holes unless the beam is structurally sound. An engineer or architect with experience in wood design should be consulted before any vertical holes are drilled.
How do you join two load bearing beams?
Each side of the beam will be supported by two side plates, one on each side of the beam. Beam height and beam width must equal the length of each side plate. On either side of the joint, the side plates should extend out at least four times the beam’s width.
Can you nail into LVL beams?
Generally speaking, it is not recommended to drill holes in IB (International Beams) or LVL (laminated veneer lumber). Table and notes below indicate that small diameter round holes, located appropriately on the wide face of the LVL, are permitted. All grades of IB LVL are affected by these rules.
What glue is used in glulam?
Types of AdhesivesGlulam can be made with a variety of adhesives. Melamine resin and phenol-resorcinal resin are polycondensation adhesives that harden through the removal of water and are called glues. Polyaddition adhesives include polyurethane adhesives.
What is in Titebond wood glue?
Polyvinyl acetate, diethylene glycol monobutyl ether, polymethylenepolyphenyl isocyanate, N-methylolacrylamide, and paraffinic oil are all found in Titebond wood glues, as well as polyurethane glue and polyurethane sealant.
What screws to use for LVL beams?
LVL multi-ply screws, girder trusses, and multi-ply lumber are all compatible with FlatLOK, a structural wood screw with a variety of uses. An installation with only one side For both ground level and elevated applications, FlatLOK is approved for single-sided installation.
Is glulam the same as LVL?
Vulcanized lumber, also known as LVL, is a manufactured timber product that is made of thin veneers (often 3mm) glued together into large structural members. Glulam is made by gluing together sections of timber that are between 15 and 45 millimeters thick.
What is the difference between LVL and PSL?
With the exception of glulam, LSL and LVL beams which are less expensive than PSL beams. Exposed PSL beams can be painted, stained, or finished in order to achieve a desired aesthetic effect. Product Laminated Veneer Lumber (LVL), like PSL, is a widely available engineered product.
Are you allowed to drill through LVL?
In most cases, drilling or notching LVL and glulam is a no-no. However, in the event that these guidelines cannot be followed, they must be. Gulam beams are made with low quality material in the middle of a beam and high-quality material at the top and bottom of each section.
Can you cut a hole in a LVL?
An LVL beam should never have a square hole cut into it, as is the case with all timber construction. Square cuts are more susceptible to splitting because of stress concentrations. Stresses can develop “more smoothly” around an opening if the hole is round (drilled).
Can you drill holes in glulam beams?
Because of the removal of fibers, the area of a glulam beam is reduced and stress concentrations are introduced by holes, just like with notches. These effects cause a reduction in the capacity of the beam in the area of the penetration.
How far can a 2×10 LVL beam span?
The LVL beam can span 60 feet and is much stronger than conventional lumber because of its high tensile strength.
How big of a beam do I need to span 16 feet?
You will need a wood beam of at least 3-2×14 or 6×14 in order to span 16 feet. It is possible to span 16 feet with a 3 nailed 2×14, 3-2×14 or 6×14 wood beam. At least 14 inches in depth and 6 inches in width (3-214) must be used for residential building, wood frame structure, or projects with a 16-foot span.
What is the nailing pattern for LVL beam?
For Beams That Are Top-Loaded, Multiple Pieces Are Connected.Only two rows of 31/2-inch nails at 12 inches apart are required for 91/2- to 117/8-inch beams. 16d (31/2″) nails, spaced 12″ apart, are required for beams 14″ to 24″ in length.
