Can LVL be used for studs?
Laminated veneer lumber (LVL) studs can be two times stronger in compression and tension than standard framing lumber of the same dimension. Recently I built a home with all LVL studs for a client who wanted the home to withstand wind and shear loads.
What does LVL mean in framing?
Laminated veneer lumber (LVL) is one of the most widely used engineered wood products for constructional applications. It is a composite product manufactured from multiple thin layers of veneer that are aligned with the length of the finished lumber.
What is the difference between I joist and LVL?
The I-joists are made from lumber flanges, OSB webs and cured adhesive. LVL (laminated veneer lumber) beams are manufactured with multiple layers of thin wood assembled with adhesive.
Are LVL beams stronger than lumber?
Laminated veneer lumber (LVL) studs can provide ultimate strength against wind and shear-loads and can be up to two and a half times stronger than standard framing lumber of the same dimension in compression and tension, which means a wood-framed house can be designed and constructed to withstand 100 mph or more .
Is LVL better than solid wood?
One of the major differences between LVL and conventional lumber is that – due to the emphasis placed on quality bonding in LVL – there are no naturally occurring knots. This not only makes the product stronger, but more durable than conventional lumber.

Are I-joists stronger than LVL?
LVL may be stronger, but inch-for-inch it is more expensive. The balance of cost vs performance is leaning in favor of sawn flanges for residential applications. Many builders prefer sawn flanges. Once builders use I-joists they are usually converted for life.
How far can a LVL joist span?
LVL beam span:- an LVL beam can span up to 60 feet due to its strength and is much stronger than traditional lumber. Generally, you can find LVL beams in a 4-foot increments starting at 24 feet and going up to 44 feet long, with special customize size up to 60 feet.
How far can a LVL beam span without support?
As per general thumb rule and guidelines, a double 18″ lvl beam can allow span upto 30 feet far distance used for residential building or projects.
Will LVL beams sag?
You will always have sag with a 14 foot header. If it is a metal i-beam maybe 1/100th of an inch... Your wood/LVL will sag much more. What you are describing is ultra typical when there is a point load above and they used LVL.
How much does a 20 foot LVL beam cost?
20 ft lvl beam price:– on average cost/ price of LVL is around $3 to $12 per linear foot. So, for 20 ft lvl beam price = 20×3 = $60 or 20×12 = $240, thus, price/ cost of 20 ft lVL beam or Laminated veneer lumber or Engineered beam would be $60 to $240 for materials or between $50 to $200 per foot for installation.
Can LVL get wet?
After the first 24 hours you can get your lashes wet. For the first two days after your LVL lashes treatment and lower LVL treatment, you should avoid all steam, saunas and swimming. After that, you can jump in and get wet with no worries – swim, shower, bathe, whatever.
What is LVL used for in construction?
Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It is typically used for headers, beams, rimboard, and edge-forming material.
Is LVL stronger than timber?
Prior to lamination, the veneers are dried and the grains of each veneer are oriented in the same direction. This makes LVL stronger, straighter and more uniform than solid timber and overcomes some of timber's natural limitations such as strength-reducing knots.
How thick is a standard LVL?
The most common thickness of LVL is 45 mm (1-3/4 in), from which wider beams can be easily constructed by fastening multiple LVL plies together on site. LVL can also be manufactured in thicknesses from 19 mm (3/4 in) to 178 mm (7 in).
What is a structural LVL?
Laminated Veneer Lumber (LVL) LVL is a widely used structural composite lumber product. It is produced by bonding thin wood veneers together in a large billet so that the grain of all veneers is parallel to the long direction. The LVL billet is then sawn to desired dimensions depending on the end-use application.
LVL Product Grades available
Murphy’s engineered veneer dimension lumber are available in 2.0E product grade.
Sizing Software Support

What is LSL board?
LSL is also made from strands rather than veneer, although the strands are shorter and aligned with less precision than PSL and is created as billets that are like a thick version of oriented strand board. Billets of PSL and LVL are very similar although their sizes are different.
What is LVL used for?
Because it is specifically sized to be compatible with I-joist floor framing, residential builders and building designers like the combination of I-joist and LVL floor and roof assemblies. LVL is considered to be a highly reliable building material that provides many of the same attributes associated with large sized timbers. LVL can also be used in combination with gluelam as an outer gluelam tension lam to increase the strength of the gluelam beam. However, due to the fact that the assembly adhesives limit the penetration of chemicals typically used to treat outdoor-rated lumber, LVL may not be suitable for outdoor load-bearing use. A deck built using pressure-treated LVL collapsed due to internal rotting of the twelve-year-old LVL components, although the LVL beams had passed regular visual inspections. The breakdown of LVL end uses in North America is 33% new single family residential construction, 25% residential renovations and upkeep, 8% new non-residential construction and 34% manufacturing furniture and other products.
What is laminated veneer lumber?
For other uses, see LVL. Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It is typically used for headers, beams, rimboard, and edge-forming material.
What is LVL lumber used for?
It is typically used for headers, beams, rimboard, and edge-forming material. LVL offers several advantages over typical milled lumber: Made in a factory under controlled specifications, it is stronger, straighter, and more uniform.
How big is a billet?
Billets of PSL and LVL are very similar although their sizes are different. Billets of PSL can be as large as 12 inches (300 mm) wide and 60 feet (18 m) long while LVL can range up to 4 feet (1.2 m) wide and 80 feet (24 m) long.
How much wood is in LVL?
Although the creation of LVL is often proprietary and thus its make-up is largely dependent on individual manufacturers, in general one cubic meter of North American lumber is composed of 97.54% wood, 2.41% of phenol formaldehyde resin, 0.02% of phenol-resorcinol-formaldehyde resin, and 0.03% fillers.
When was Lvl first released?
The 1991 release is the first release which mentions LVL. LVL is mentioned as a subcategory of structural glued laminated timber. The first explorations into engineered lumber happened during World War II in the United States. In 1942, an increased demand for wood caused a sudden timber shortage.
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.
How to get to finished LVL beam?
The process to get to a finished LVL beam starts with debarking the log, then rotary peeling the veneer to send the sheets to the jet tube dryers to reduce the moisture content to 8-10%.
How long is a LVL beam?
Generally, you can find LVL beams in 4-foot increments starting at 24 feet and going up to 44 feet long, with special orders up to 60 feet. LVL beam thickness is usually between 1 ¾ and 7 inches.
Why do water heaters need seismic straps?
Source Seismic straps are critical when using water heaters if you live in an earthquake-prone area. They prevent the water heater from tipping backward as the ground shifts. But there is a...
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.
Why not use steel studs?
I know what you’re thinking: Why not use steel studs? They’re cheaper and lighter. They are also dead flat. True indeed, but steel studs aren’t structural or load-bearing, and our residentially focused trades don’t know how to work with them. With steel, trim requires screws instead of nails, electricians need to take caution when running Romex cable, framers don’t know how to assemble them, and dealing with wood bucks for doors and windows is a pain. In short, LSL and other engineered studs are a one-to-one replacement for standard 2-by studs, so it’s business as usual.
What is LP solid start lumber?
LP SolidStart laminated strand lumber installs like traditional framing but surpasses it in strength and consistency. It comes in long lengths and has low moisture content.
What are the downsides of engineered lumber?
So what are the downsides of engineered lumber? For one, it’s pricey. Softwood lumber is a commodity whose price fluctuates with the markets. Engineered lumber tends to be more price-stable, but it has upcharges of anywhere from 1 ½ to more than two times the cost of traditional lumber.
Is engineered studs stronger than standard studs?
In addition to being flat and straight, engineered studs are strong. Laminated veneer lumber (LVL) studs can be two times stronger in compression and tension than standard framing lumber of the same dimension. Recently I built a home with all LVL studs for a client who wanted the home to withstand wind and shear loads.
Can I use engineered studs for a wall?
In conclusion, engineered studs can offer a lot of benefits, but they aren’t without some downsides. If you’re using traditional pine lumber, talk to your supplier about premium options to see how they compare in price with engineered. In many parts of the country, you can find excellent Doug fir studs for not much more than SPF, and that may get you 80 to 90 percent of what you need. I’d also recommend trying engineered lumber on a tall-wall application or a kitchen first, to get the most bang for your buck. Good luck on your next build!
Does engineered lumber absorb leaks?
Engineered lumber doesn’t have the ability to absorb small leaks. If it does get wet and can’t dry (inside a wall cavity, for example) it will rot faster than dimensional lumber. I typically use regular CDX plywood sheathing on my engineered stud framed homes to provide more hygric-buffering than OSB sheathing offers.
Can you add videos to your watch history?
Videos you watch may be added to the TV's watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer.

History
Structural composite lumber products, including LVL, are a relatively recent innovation. They are the result of new technology and economic pressure to make use of new species and smaller trees that cannot be used to make solid sawn lumber. While plywood became widespread by the early 20th century, the invention of LVL was not until the 1980s after the invention of oriented strand board. The American Wood Council's National Design Specification for Wood Constructio…
Qualities
Laminated veneer lumber is similar in appearance to plywood, although in plywood the veneers switch direction while stacking and in LVL the veneers all stack in the same direction. In LVL, the direction of the wood grain is always parallel to the length of the billet. The stacking of these veneers into a complete board, called a billet, creates a single piece of LVL sharing a common direction of wood grain. LVL is typically rated by the manufacturer for elastic modulus and allow…
Manufacturing
LVL is commonly manufactured in North America by companies that also manufacture I-joists. LVL is manufactured to sizes compatible with the depth of I-joist framing members for use as beams and headers. Additionally, some manufacturers further cut LVL into sizes for use as chord-members on I-joists. In 2012, North American LVL manufacturers produced more than 1.2 million cubic metres (43.4 million cubic feet) of LVL in 18 different facilities, and in 2013 the productio…

Structural composite lumber
LVL belongs to the category of engineered wood called structural composite lumber. Other members of this category are parallel strand lumber (PSL) and laminated strand lumber (LSL). All members of this category are strong and predictable, and are thus interchangeable for some applications. PSL is made from veneers that are cut up into long strands and oriented parallel to its length before being compressed into its final shape. LSL is also made from strands rather th…
