A Variety of Species: Exploring the Visual Qualities of Glulam Beams
In the realm of timber construction, glulam beams stand as not just structural elements. Their visual appeal, influenced by the species of wood used, adds a touch of natural elegance to any architectural design. Let's embark on a journey through the diverse species of wood commonly used in glulam production and the unique visual qualities they impart to these remarkable engineered beams.
What species are available?
Spruce
Visual Qualities: Spruce is known for its pale, creamy color with subtle variations in tone. Its fine, straight grain creates a clean and elegant appearance, making it a popular choice for contemporary architectural designs.
Applications: Spruce is the most common species of timber used in glulam construction due to how readily available the raw material is in Europe. It is a versatile timber that is widely used in both commercial and residential projects due to its consistency and availability.
European Larch
Visual Qualities: European Larch is known for its pinky-brown hue which adds a different dimension to projects that select this species.
Applications: European Larch is slower grown than the more commonly used spruce. Therefore it is suitable, in the right circumstances, to be used in external environments. Therefore it is seem often in service class 2 / 3 uses such as pergola and canopies.
Douglas Fir: Strength and Beauty
Visual Qualities: Whilst similar in appearance to European Larch, Douglas Fir has a warm, reddish-brown hue, often interspersed with swirling grain patterns, lends a sense of timeless elegance to glulam beams.
Applications: Widely used in both residential and commercial construction, Douglas Fir glulam beams are favored for their durability and versatility. From exposed roof structures to grand entranceways, they make a statement of strength and beauty along with a great alternative to the more commonly used European Larch.
European Oak
Visual Qualities: Oak glulam offers the pinnacle of laminated beams. Using the highest quality raw material available, European oak offer a clean and classic look that is unmatched.
Applications: Generally used in high end construction, European Oak offers that wow factor that sets it apart from other species of timber. Oak has been used in construction for centuries, through lamination we are able to bring this to the 21st century with a modern take on a classic timber species.
Sweet Chestnut
Visual Qualities: Sweet chestnut is great alternative to European Oak. Being a hardwood, just like oak, Sweet Chestnut offers a strikingly similar visual appearance but at a lower cost.
Applications: This is perfect for a client wanting to do things slightly different from the norm. This is a niche product that can really bring out the best of timber engineering.
Visual Grading: Defining Quality and Character
In addition to the species of wood used, the visual grading of glulam beams plays a significant role in determining their quality and character. The visual grading process involves assessing the appearance of the wood, including factors such as knots, color variations, and surface imperfections. Spruce glulam adheres to two surface qualities which is defined by the BS Holz Bulletin.
Customization and Design Freedom
The diverse range of wood species and visual grading options in glulam construction offers architects and designers unparalleled flexibility and creativity. Whether aiming for a sleek modern look, a cozy rustic charm, or a timeless classic appeal, the choice of wood species and visual grading allows for precise customization to suit the vision of each project.
Conclusion: Where Nature Meets Design
