FAQs About Microlam Beams
Here are some frequently asked questions to help you understand more about Microlam beams and their applications.
What exactly are Microlam beams?
Microlam beams, also known as laminated veneer lumber (LVL), are engineered wood products. They are made by bonding thin wood veneers together under heat and pressure, creating a strong and consistent structural member. This process makes microlam beams stronger than traditional lumber.
What are the primary advantages of using Microlam beams?
Microlam beams offer several advantages, including their high strength-to-weight ratio. They are also less prone to warping, twisting, or shrinking compared to solid wood. Their consistent dimensions make them easier to work with in construction projects.
Where are Microlam beams typically used in construction?
Microlam beams are versatile and used in a variety of structural applications. Common uses include headers and beams in residential and commercial buildings, floor joists, and roof rafters. They can also be used for long spans where solid lumber may not be adequate.
How do I choose the right size of Microlam beam for my project?
Selecting the correct size of microlam beam requires careful consideration of the load it will bear and the span it needs to cover. Consulting with a structural engineer or experienced builder is highly recommended to ensure the beam meets all safety requirements and building codes.
