Unveiling the Craft: A Dive into Glulam Construction
In the world of modern construction, glulam stands as a testament to both innovation and tradition. A material that combines the strength of timber with the versatility of modern engineering, glulam beams have become a staple in architecture and construction across the UK. Here we will explore how glulam is made, the various types of glues utilized, and the standard sizes that are produced.
Glulam – the basics
What is Glulam?
Glulam, short for "glued laminated timber," is a structural timber product composed of layers of dimensioned timber bonded together with durable, moisture-resistant adhesives. This engineered wood product is renowned for its exceptional strength, stability, and aesthetic appeal, making it a top choice for architects, engineers, contractors and clients.
The Manufacturing Process
The creation of glulam beams begins with carefully selecting high-quality timber, sourced from sustainably managed forests. Logs are cut into smaller sections, which are then kiln-dried to reduce moisture content (typically 10-12%), ensuring the stability of the final product.
Next comes the crucial process of laminating. Individual timber strips, known as lamellas, are graded for strength and appearance before being coated with a specially formulated adhesive. These lamellas are then stacked in a specific orientation to maximize strength and stability.
Pressing and Curing
Once the lamellas are coated with the adhesive, they are assembled into the desired beam configuration. The entire assembly is then placed into a high frequency press, which rapidly presses and cures the glue in a matter of minutes.
Standard Sizes and Applications
Versatility in Dimensions
Glulam beams are available in a wide range of standard sizes to suit various structural requirements. These sizes typically range from small sections, such as 80 x 120, up to large sections up to 2m deep which allow for long spans.
Common Applications
The versatility of glulam extends its applications across an array of construction projects:
Roof Beams: Glulam's strength-to-weight ratio makes it ideal for long-span roof structures, allowing for open and airy architectural designs.
Floor Beams: Used to support floor loads in residential, commercial, and industrial buildings, glulam beams provide both strength and aesthetic appeal.
Architectural Features: From striking arches to intricate trusses, glulam allows architects to unleash their creativity, shaping spaces with both strength and elegance.
Conclusion: Where Tradition Meets Innovation
As we delve into the world of glulam, we uncover a material that bridges the gap between tradition and innovation. With a deep understanding of how glulam is made, the types of glue that bind its strength, and the standard sizes that define its form, we gain a newfound appreciation for this remarkable construction material. Whether supporting the roof over our heads or framing the breathtaking architecture that inspires us, glulam beams continue to shape the world we live in, one laminated layer at a time.
