Microlam beams, or laminated veneer lumber (LVL), can present hazards related to their manufacturing process, which often involves adhesives that may emit volatile organic compounds (VOCs). Prolonged exposure to these compounds can pose health risks, including respiratory issues. Additionally, if not properly designed or installed, microlam beams can fail under excessive loads, leading to structural failures. Regular inspections and proper handling can mitigate some of these risks.
MIcrolam is very similar to lumber, but it is much stronger. it is made with the same layering technique, but has more durablilty, and requres less supporting beams. Microlam would be a great choice for a deck.

Microllam is typically sawed into 1.25 inch wide planks. These planks are made into beams that span up to 16 feet.
I checked and per a Roseburg Forest Products booklet holes up to 2" are permitted as follows: No more than 3 holes. Square and rectangular holes are not permitted. Does not apply for cantilevers. Hole to be centered on height of beam. Holes (if more than one) must be a minimum of 4" clear distance between holes. Hole must be at least 2 1/2 times height of beam away from load bearing point
As a roof truss/I-joist/beam designer, I can tell you that you should not cut ANY holes in a microlam beam without consulting an I-joist/beam designer first. Microlam beams are not calculated to have holes cut in them. This requires special engineering.Depending on the size of the hole and it's placement, and the load that the beam is carrying you may not be able to cut a hole in it at all. Considering the 25' length (if this is a clear-spanning beam) I can warn you that abeam designer is probably going to tell you to find a different solution for this issue.Hope this helps!
Microlam (or glulam) is an engineered timber product that is made from layers or wood held together with adhesives. The end product is generally made into lengths or beams that are stronger and less prone to warping and twisting than standard timber products.
Yes, microlam, or laminated veneer lumber (LVL), can be ripped, but it requires the right tools and techniques. It's important to use a sharp, high-quality saw blade to ensure a clean cut and to minimize splintering. Always follow safety precautions and manufacturer guidelines when cutting engineered wood products like microlam.
unless you got a great deal on them, it would never make $$$ sense to use a microlam in lieu of a TJI joist or dimensional lumber. . .microlam is too costly if you have them on hand, I would call the manufacturer. . .they should be able to give you the numbers or send you a book with the span charts
The weight capacity of a microlam beam depends on its size, span length, and load distribution. It is important to consult a structural engineer to determine the specific weight capacity for your particular application.
It is built into the multifunction switch which controls your signals,high beams,cruise,etc...have to replace entire unit.
you must have a blowed fuse.
Yes, The multiple layers of wood glued together makes them 50x stronger than standard lumber.
