Microlam wood is often used for beams and beams in construction.
A microlam, sometimes called a lam beam or laminated laminated lumber (LVL), is a type of engineered lumber. It is notable because it is much stronger than plywood, although it is made in a similar way. There are many uses for strong wood like microlame, but it can be quite expensive when compared to other materials, so the use of lam beams is generally reserved for cases where a large amount of strength is required. Common uses include transporting beams, beams and headers.
The way microlam is made is the secret of its strength. Like plywood, thin sheets of wood are glued together to create beams. Each layer is glued so that the grain direction alternates, providing strength in each direction. The glue is very strong and when the entire beam is assembled it is heavy and considered suitable for construction.
A microlam beam usually looks a lot like plywood. It usually has a smooth face with identifiable straight layers running in parallel. These layers are usually seen on both sides of the beam, although they can be hidden. Microlam beams come in a variety of sizes for different purposes. They can also be fastened together, creating a stronger main beam.
Although laminated beams are mostly used in new construction projects, they are also useful in expanding a home. Plucking out exterior walls for additions may require the use of strong, compact beams like these. Consulting with a trained construction professional is a good strategy to determine which type of lumber is best for the project, but the hardware store personnel can help determine if a lam joist is needed.
The main benefit of a microlam beam is that it can do the job of a larger piece of wood using less space. It is only economical, then, to use this type of wood when these characteristics are an advantage. Replacing beams that have started to sag in a home with microlam beams may not be justified because there will be little benefit. In new construction, the use of laminated beams saves space and allows for fewer support posts.
There are other benefits to using this type of lumber designed over milled wood. Lam beams are generally straighter and more uniform than their milled counterparts. Composite beams such as these generally have a lower risk of deformation over time, such as warping, shrinking, or bowing. This wood offers reliability due to its artificial nature. While natural materials and techniques are desirable for some purposes, the use of engineered materials in construction provides additional safety and long-term benefits for homeowners.
