How Glulam Supports Sustainable and Fast Building Practices
As more builders seek eco-friendly, durable and functional building materials, glulam has quickly become the go-to material. With long span capabilities that help architects push design boundaries without needing additional structural supports, glulam beams have quickly become the go-to choice.
Glulam buildings have proven themselves corrosion-resistant and can withstand harsh environments like salt storage domes and potash warehouses, while simultaneously reducing carbon emissions during both construction and operations phases.
Structural Strength
Pound for pound, glulam is far stronger than steel and capable of withstanding much greater loads than dimensional lumber. Furthermore, it’s far more flexible than its counterpart, making glulam an excellent choice for architectural applications where large open spaces need to be created. Its structural capacity can be further increased using high-grade wood species combined with innovative design techniques – depending on the project builders may use multiple species to reinforce glulam’s core which typically comes from either SPF (spruce pine fir), Douglas Fir or Larch wood varieties.
Glulam is an extremely durable material with long lifespan, which reduces maintenance costs and is eco-friendly as its production uses only minimal energy to manufacture and transport it; additionally, this material can even be recycled back into new projects or utilized as biofuel.
Glulam offers additional environmental advantages by acting as an insulator that lowers energy bills – something which makes it ideal for projects seeking certification such as LEED.
The production process for glulam uses wood from sustainable sources and has lower emission-intensities compared to concrete and steel building materials, as a significant portion of energy needed is drawn from renewable resources – meaning less emissions and reduced fossil fuel use!
Glulam is also an ideal material choice for large buildings that must accommodate many people at once. Airports require vast interior spaces that can be easily accessed by many passengers; using glulam to support its roof over such an expansive area without additional columns allows for a more open layout, creating structures that are safe and welcoming to everyone – perfect for modern structures that must simultaneously serve functional purposes and look stunning.
Thermal Insulation
Glulam’s strength, versatility and aesthetic appeal make it an excellent material choice for many projects. From stunning applications like vaulted ceilings and dramatic trusses to more hidden uses such as purlins, ridge beams, garage door headers and floor beams glulam combines beauty with structural excellence to support form and function while builders rely on it due to its ability to reduce structural supports required for large open spaces; saving on materials costs and labor hours in doing so.
Glulam is also environmentally responsible. Crafted from sustainably harvested wood that undergoes stringent quality assurance programs, its production involves computerized system evaluation of every piece for grading, knot size/shape/moisture content before joining it together using structural glue (typically an RF curing melamine formaldehyde or phenolic resin glue) with minimal energy consumption and less waste production compared to sawn lumber production processes; furthermore it’s recyclable when its lifecycle ends.
Aesthetics: Glulam’s aesthetic options make it suitable for many architectural styles and architectural periods, from modernist to classical. Furthermore, its material allows it to be formed into different structural forms including arches and curves for further customization.
Durability: Glulam boasts high dimensional stability, making it less vulnerable to expansion or contraction due to changes in humidity. For members that may come into contact with water, however, preservative treatment may be required for optimal preservation.
Environmental Sustainability: Life Cycle Assessments (LCAs) have shown that glulam buildings produce lower total lifecycle carbon emissions than steel or concrete buildings, due to advanced forest certification systems, use of renewable energy during production, and optimized logistics networks.
Lightweight
Glulam is lighter than concrete or steel, requiring less energy for transport and construction, plus its natural insulating properties help lower operational energy usage and emissions further. When combined with renewable energy systems, these low-emitting materials make an excellent solution for cold climate regions where heating costs and greenhouse gas emissions often outstrip other sources.
Contrasting with dimensional lumber, which comes from mature and old-growth forests, glulam is made up of smaller pieces harvested from younger trees in second and third-growth forests – making it significantly more sustainable than its counterparts as it takes less time for replenishing supplies.
Glulam comes in several appearance grades to meet specific design and aesthetic goals. Rosboro’s X-Beam DF and Big Beam DF architectural beams, in particular, feature architectural appeal that complements any building design. Both options feature adjustable width and length settings that can meet a project’s unique span requirements while their wide flanges make them compatible with standard metal hangers and fasteners, simplifying MEP (Mechanical, Electrical and Plumbing) requirements more easily.
Gulam allows architects and designers to create more open spaces with less structural support, making glulam an ideal material for large buildings like ballrooms or wedding chapels where an uninterrupted view is desired. Furthermore, its versatility enables it to be formed into curvier shapes.
Durability
Glulam structures are constructed by adhering layers of kiln-dried structural-grade timber together using durable adhesives, creating structures with unprecedented stability – minimising twist, split and shrinkage tendencies. As a result, posts, beams, trusses made with glulam offer superior load bearing capacity and spanning capabilities; Prolam’s PLX20 Beam and PLX Portal hybrids raise the bar even higher by offering timber alternatives with greater durability than steel beams and portals.
Strength of glulam also allows it to offer greater design versatility, accommodating for curved and sloping areas with ease, creating stunning vaulted ceilings, curved stairs and other unique features that improve building aesthetics. Plus its resilience against torsional stresses make glulam an excellent material choice for projects requiring significant deflection without losing stability.
Comparable to their concrete-and-brick counterparts, glulam buildings exhibit lower operational emissions over their lifetime and use less raw material; furthermore, using wood from sustainably managed forests decreases overall carbon footprint of structure.
Glulam’s fire resistance is excellent and its charring characteristics allow it to protect the integrity of structures after 30 minutes of exposure, making glulam an appealing alternative to concrete or steel structures, which may quickly lose structural integrity under similar conditions and collapse quickly.
In addition, glulam manufacturers often utilize glue bonds with high tensile strength and bonding methods that resist corrosion to allow their product to be used in environments with harsh environments like salt storage domes and potash warehouses. Furthermore, all manufactured glulam members undergo quality assurance testing to ensure they meet manufacturing standards – this includes glue bond test results, lumber grading requirements and end-joint testing as part of an exhaustive checklist.
Sustainability
Environmentally friendly glulam is also an ideal choice for buildings requiring strength and flexibility, such as open layouts or long spans. Fabricators can create both straight and curved designs using this material – perfect for long spans or layouts with long spans or open layouts. Furthermore, its superior fire and acoustic performance makes glulam an exceptional long-term choice, requiring far fewer repairs or maintenance services than its steel or concrete rivals.
Glulam also boasts a lower carbon footprint than steel or concrete, made of renewable wood from managed forests that prioritize reforestation efforts and environmental concerns. Glulam can be manufactured using different species such as spruce pine and larch, while it can even be bent into curves and arches to form arched structures.
Because glulam is prefabricated, it can help reduce both construction time and costs. Shipped directly to job sites dry for easy assembly, this saves on shipping expenses as well as storage fees on site. Furthermore, its lightweight nature allows larger structures to be assembled faster.
A glulam structure can be built using various types of connections, including bolts and steel connectors, as well as various lubricants designed to withstand heavy loads and weathering.
Glulam is an ideal material choice for both commercial and residential projects, providing both strength and flexibility when required – such as in high-rise construction projects. As a long-span support solution or open design material, Glulam also boasts better sustainability than concrete or steel production methods, with lower carbon emissions during production, acting as an environmental carbon sink over its lifespan and acting as an organic carbon sink during its lifecycle.
