Glued laminated timber is a highly innovative construction material engineered to meet specific load requirements. It is a stress-rated engineered beam of wood laminations bonded with durable, moisture-resistant adhesives. The grain of the laminations runs parallel with the length of the member. Glulam is versatile, ranging from straight beams to complex, curved members. It is more vital than steel and has greater strength and stiffness than comparably sized dimensional lumber. Increased design values, improved product performance, and cost competitiveness make Glulam the superior choice for manufacturing trusses.
QB Corporation uses dry lumber that is checked for suitable moisture content and graded board by board. Then, boards are finger-joining the lumber to form longer laminations that will be bonded together. This process is carried out under controlled conditions that minimize warping, twisting, checking, and defects seen in solid sawn. This makes Glulam a high-quality, universally usable product in timber construction.
When it comes to strength and flexibility, Glulam outperforms steel in many ways. Glulam offers superior load-bearing capacity with a strength-to-weight ratio that is three times greater than steel. This means that pound for pound, Glulam is indeed stronger than steel.
The advantages of Glulam continue beyond strength. Here are a few more reasons why Glulam trusses are becoming the preferred choice over the alternatives.
Lightweight: Glulam is lighter than steel for the same load-bearing capacity thanks to its high strength-to-weight ratio. This makes Glulam trusses easier to maneuver and install, saving time and effort.
Flexibility: Whether you’re working on a long-span project or a curved design, Glulam is the perfect choice. Its flexibility allows for creative designs without compromising on aesthetics.
Durability: Glulam is more durable in environments with high moisture or chemical levels and requires less maintenance than steel. This makes Glulam trusses a practical choice for a wide range of projects.
QB Corporation is proud that QB Glulam trusses are generally considered more environmentally friendly than steel and solid-sawn trusses. Here are a few reasons why:
Lower Carbon Footprint: Glulam has a lower carbon footprint than steel and concrete. This is because the production of Glulam requires less energy and results in fewer greenhouse gas emissions.
Sustainable Material: Wood is a renewable resource, and the timber used in Glulam can be sourced from sustainably managed forests while using the wood more efficiently than solid sawn.
Life Cycle Analysis: When considering the entire life cycle of the building product – from extraction of the raw material to demolition of the building at the end of its lifespan – wood was found to be better for the environment than steel or concrete in terms of embodied energy, global warming potential, air emissions, water emissions, and solid waste production.
