Also known as microlam, LVL is made from peeled or sliced thin veneers laid in a parallel arrangement and bonded together under heat and pressure. LSL is typically less expensive than other engineered wood beams. Let’s Fill Our Cities With Taller, Wooden Buildings. Nowadays the most widely used wood-based products available on the market are Glued Laminated Timber (Gluelam), Cross-Laminated Timber (CLT), Laminated Veneer Lumber (LVL), Laminated Strand Lumber (LSL), and Parallel Strand Lumber (PSL). PSL beams are generally more expensive than glulam, LSL, or LVL beams. The first building to get everybody excited was the Murray Grove tower, designed by Waugh Thistleton; interest in the material immediately exploded, given headlines like Nine Storey Apartment Built Of Wood in Nine Weeks By Four Workers.
And the two most popular options among builders are. Both glulam and LVL have their own set of advantages in the construction industry. Another niche for Simon is travel and outdoors leisure, including sporting equipment and bikes. Even the New York Times is on it, recently publishing Let’s Fill Our Cities With Taller, Wooden Buildings. Is Mass Timber Construction Really Renewable and Sustainable?
This especially proves helpful in retrofit projects where lifting a big, heavy beam is difficult or impossible. It's also really beautiful, as you can see in the Vitsoe headquarters. Stud options are available in equivalent 2×4, 2×6, and 2×8 sizes that are stronger, straighter, and (as needed) longer than sawn lumber. Due to the strength and stiffness glulam construction offers, it’s often an essential component used for building vaulted roofs, domes, and bridges. A glulam unit looks like a well-bonded stack of large lumber glued together. For starters, glulam timbers are very strong, highly customizable, and cost-effective. Although they’re much lighter than concrete and steel, they’re extremely strong. While not as strong as LVL or PSL beams, LSL is generally cheaper and are ideal for short spans. Builders and designers enjoy a number of benefits by using glulam in their construction projects, including: Glulam can be used in a myriad of ways – from the roof and floor beams, and columns to decking and bracing, Have a unique capability of creating up to 500 feet of unsupported spans, Contain low levels of formaldehyde and thus, are environment-friendly, Cut down the handling and transportation costs, Can easily be customized to meet special design requirements, Are readily available in standard lengths and widths, Have amazing fire-resistant properties, better than steel beams, Are manufactured in well-managed forests and are PEFC-certified. The classification of glue-laminated timber members is based on their unique strength properties and their rating on a stress classification system. Glulam is most commonly used in the construction of large buildings, including universities, airport, hotels, and museums. Our VERSA-LAM ® LVL is manufactured in either Alexandria (Lena), Louisiana in Eastern United States, or in White City, Oregon for the Western United States. The first part of the rating refers to their reference bending design value while the second part is their modulus of elasticity value. Design professionals should be knowledgeable about specific product availability and costs in their areas during design as this can help drive which types of engineered wood beams are specified.
Make Your Home Holiday Ready With These Weirdly Amazing Upside Down Christmas Trees! And the two most popular options among builders are glue laminated timber (glulam) and Laminated Veneer Lumber (LVL).

Common PSL beam sizes are available in widths of 3 ½, 5 ¼” and 7”, and depths matching I-joists from 9 1/2” – 24” deep. Glued Laminated Timber (Glulam) is manufactured by face-bonding layers of kiln-dried timber members, typically 2×4 or 2×6 in size, together with waterproof adhesives to form timber section. Glulam is typically used for the beams, while cross-laminated timber is typically used for floors and walls. This article will focus on two specific types of engineered wood products, structural composite lumber (SCL) and glue laminated (Glulam) timber framing. Most, if not all modern wood-framed buildings use engineered wood products. In the event that there is still a problem or error with copyrighted material, the break of the copyright is unintentional and noncommercial and the material will be removed immediately upon presented proof. Both glulam and LVL are strong materials in their own roles. Since they are made with smaller pieces of lumber, they are also resource-efficient. James Henderson of Brettstapel.org explains: I think it was StructureCraft that renamed it DLT to fit in with all the other LTs. Moreover, glue-laminated timber shouldn’t be exposed to outdoor conditions until they’re ready for installation unless of course, they’re specially made for outdoor areas. Most, if not all modern wood-framed buildings use engineered wood products. Glulam beams are typically manufactured for a specific design.
Holz100 is a cross laminated timber held together with dowels. The Guardian Covers Tall Wood Construction; We Cover the Comment Section.

When it comes to storage, the ideal position is vertical. This is especially beneficial in retrofit options where lifting a wide, heavy beam into place is cumbersome or infeasible. Cross-Laminated Timber, or CLT, differs from Glulam in that the wood is glued up with each layer of boards being perpendicular to each other. Delivers maximum structural reliability and considerable strength, Has fire-resistant properties similar to solid timber, burns at a slow and predictable rate, Small wood pieces can easily be made into large LVL beams, Can easily be cut and machined with regular woodworking tools, Simon is an entrepreneur and self-proclaimed jack of all trades. Simon has experience in the building and home renovation industry and he knows what it takes to knock out a successful project whether it be commercial or residential. The aesthetics of NLT are a bit rougher, with that warehouse look that people want these days, without all the trouble of old warehouses. What is everyone talking about here? As far as weather damage is concerned, short-term exposure doesn’t really affect its performance but long-term exposure can. A big kid at heart if it goes fast, bounces, slides or you can climb it Simon has put it to the test. The strong engineered wood beam is typically used for structural applications. It’s important to note that they should be dry before they’re installed. Typical stock beams widths are available in 3 1/8”, 3 ½”, 5 1/8”, 5 ½”, 6 ¾” widths and depths exceeding SCL beams. Holz100 is a cross laminated timber held together with dowels. Everything Old Is New Again With the T3 Building in Minneapolis. An interesting new variation is this Holz100, which is like CLT, with the lumber running in layers perpendicular to each other, held together with dowels like DLT, so that there is no glue needed. It is used like Glulam, for columns and beams, but compared to lumber it is stronger, straighter and more uniform, and takes greater stresses than Glulam.
Coincidentally, I took a lot of photos in Quebec City to do this kind of story. Members are commonly fabricated in 1 ¼”, 1 ½”, 1 ¾” and 3 ½” widths, and in 9 ¼”-16” depths to match common i-joists. If CLT is known as plywood … Both glulam and LVL have their own set of advantages in the construction industry. This often eliminates the use of LSL, and glulams are usually preferred over LVL and PSL due to cost, appearance, or available beam sizes. Why Is Architecture and Building So Different in Europe? I wrote back then, when it was just barely creeping in to North America: Nail Laminated Timber or NLT is the stuff that the T3 building is made of, because there was not enough CLT capacity in North America to make that big a building, and supplier StructureCraft recommended NLT as an alternative. In an area that requires stunning surfaces to retain everyday traffic wear while preserving a naturally elegant look. Is Cross-Laminated Timber the New Concrete? Not only this, you can also get a larger beam made by simply nail-laminating several plies together. Understanding the intended uses and differences between various SCL products and glulam framing is essential for design professionals. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL. The following are some of the amazing benefits offered by LVL. Few other SCL treatment options exist. They all store Carbon Dioxide, and are all part of the mass timber revolution.
Due its high allowable shear strength, LSL beams have capacity for larger penetrations than other engineered wood beam options. SCL consists primarily of three products: Laminated Strand Lumber (LSL), Parallel Strand Lumber (PSL), and Laminated Veneer Lumber (LVL). Surface scratches are very common when handling glulam and so, make sure that you always use fabric slings when lifting it. Below are a few common uses of it: The strength of LVL can be compared with that of steel, concrete, and solid timber. NLT is cheaper and anyone with a nailgun and a strong back can make it; CLT requires significant investment, which is why it is still expensive. Both SCL and glulam beams may be used where a fire-rated exposed member is required, subject to meeting the provisions of Chapter 16 of AWC’s National Design Specification® (NDS®) for Wood Construction. An lvl is a structural element intended to be concealed so is made of low grade or inexpensive plywood materials.
The standard sizes of LVL include widths of 3 ½, 5 ¼, and 7 inches, and depths from 9 ½ to 24 inches deep. Simon has experience in the building and home renovation industry and he knows what it takes to knock out a successful project whether it be commercial or residential. Glulams are popular due to their engineered strength, versatility, availability, and cost. Manufacturing processes for glulams allow for members to be cambered, curved, and fabricated in unique shapes, such as arches or as bridge members.
