You may have heard about Glulam construction if you are.looking for a durable, sturdy material for your building. It is an engineered wood product with superior strength and stiffness. The structurally engineered wood product also offers advantages, such as excellent fire resistance and sound-absorbing properties. Please find out how it can improve your building’s construction and save you time and money! Here are some of the benefits of glulam construction.
Glulam is a structurally engineered wood product.
Glulam is a structurally engineered wood product made from layers of dimensioned lumber bonded with moisture-resistant structural adhesives. Its unique properties enable the construction industry to use smaller lumber dimensions to construct structural elements with longer, straighter, and stronger beams and columns. Glulams are available in standard sizes and many curved shapes. Glulams are often used for floor beams in residential buildings.
Glulam is naturally durable, and pressure-treated timbers made of seasoned lumber are more resistant to movement due to changes in moisture content. However, Glulam is still subject to swelling, shrinkage, and delamination, and it should be used with caution in environments with large fluctuations in temperature. This makes it crucial to select a manufacturer that complies with stringent quality standards.
Glulam is a structurally engineered wood product made of individual pieces of dimensional lumber. The laminations are stacked and glued in a straight or curved configuration. Its structural integrity is maximized by placing the strongest laminations on the bottom and the weakest on the top. Certification assures the quality of Glulam from the APA-EWS quality control program and by consulting professional engineers.
Glulam is a structurally engineered wood product that maximizes the structural value of wood. Because prominent glulam members are manufactured from many small trees, second or third-growth forests can be used to make them. The use of Glulam in construction has reduced the overall amount of wood used and minimized the negative environmental impact of minor defects. It is ideal for decks, boardwalks, pergolas, and other structures that need to be sturdy.
Unlike traditional timber, Glulam is more potent than solid beams. It can be bent to form more extended arches without needing a supporting beam. Glulam is more reliable than concrete beams because its imperfections are minimized by other lams nearby. Its strength is comparable to steel’s, but it is much lighter. This gives it a unique advantage over many traditional building materials.
It offers superior strength and stiffness.
By lightweight, highly engineered timber, Glulam construction can offer superior strength and stiffness. The fact that Glulam can be reinforced on the tension side means that the cross-section and timber grade can be reduced while maintaining the same stiffness and strength. Further, this construction method can improve the strength and stiffness of existing structures. For instance, in a recent study, glulam beams were strengthened with FRP materials on the tension side, which significantly improved the bending strength and stiffness of the beams. The added reinforcement ratio consisted of additional fibre cloth layers and a pre-stressing process that added strength and stiffness to glulam beams.
Glulam is a newly popular engineered wood product. Its superior strength and stiffness make it a preferred choice for various applications. Glulam beams provide unmatched power, stiffness, and beauty. Unlike steel or concrete, Glulam uses less energy to manufacture. Glulam beams also provide more excellent fire resistance than conventional wood, which increases the overall efficiency of construction projects.
Glulam is an excellent choice for buildings because of its versatility. Glulam provides all the advantages of wood, such as sturdiness, ease of workability, and connecting structural components. Furthermore, timber is more stable than standard dimensional lumber and is the preferred choice for building long-span structures. The limit of a span is not always determined by the strength of the material but by the production capabilities and manageability of the completed structural element.
It is fire-resistant.
The structural design of glulam construction makes it fire-resistant. Several tests have proved its fire resistance. Fire resistance of glulam beams and columns was tested at an approved facility. All the tests passed ASTM E119-16a, “Standard Test Methods for Building Construction and Materials”, Chapter 7 of the International Code for Standards and Codes for Building Construction and Safety. These results will help engineers and architects specify glulam construction for future projects.
However, the mass timber building industry has not easily secured approvals from code officials. This means the mass-timber building industry does not have the same safety standards as mass-timber buildings. Having the necessary fire safety rating will help designers comply with Type IV construction standards. As a result, future building projects will be easier to obtain approval from the authority having jurisdiction. Glulam construction is now available in the United States.
The fire-resistant properties of glulam construction were tested using Douglas fir, a major imported species in the region. The two species were tested with different assembly methods. The Douglas fir and cedar species failed the test for temperature safety and charcoal layer decomposition. Despite the favourable results, there is still room for improvement. There are still a few ways to improve the fire safety of glulam construction. Still, one key benefit of this construction method is that it is relatively inexpensive compared to other materials.
It is sound-absorbing
Glulam is a wood composite that exhibits impressive sound-absorbing properties. Its thermal properties prevent thermal bridging and contribute to efficient building envelope assembly. Additional insulating materials can be combined with Glulam, usually added post-manufacturing. Glulam can also reduce the overall building’s sound transmission loss by as much as 80%. In addition to sound-absorbing properties, Glulam is also incredibly cost-effective.
The construction of Glulam is considered to be highly effective in sound insulation, and this fact has led to a new approach to mass timber construction. Using finger jointing instead of a butt joint increases surface area, creating a stronger joint that transmits load in shear across the glue line. This method produces a panel with a performance close to continuous laminations made from a single piece of timber.
Glulam can be manufactured virtually any size, though practical reasons limit its length to around 16 to 30 metres. This is due to the pot life of the adhesive used and because complex lay-ups take too long. It can produce Glulam in many shapes, including curved prismatic beams. The glulam material is incredibly sound-absorbing, so even if the ceiling isn’t soundproof, the sound-absorbing properties of this wood composite will help keep the building comfortable for everyone.
Glulam construction is more flexible than CLT because it offers an open floor plan that allows partition walls to be constructed or removed with minimal effort. Glulam is also more affordable than timber, which allows for a more excellent range of design possibilities. For example, glulam beams are a perfect choice for open-plan buildings, as they can be easily rearranged to accommodate different shapes and configurations.
