Multilayer glued wood

Glulam beams - BSH wood

We offer glued laminated beams made of glued laminated timber, also known as laminated woodalso known as “BSH” (from German = Brettschichtholz) or “GLULAM” (from Eng. Gluelam = Glued Laminated Timber). It is known for its outstanding qualities and diverse applications. It is created through a unique process that involves bonding multiple layers of high-quality wood together using high-strength adhesives. This manufacturing technique results in a product that offers numerous advantages over traditional solid wood or other engineered wood products.

Advantages of the offered multilayer glued timber – BSH:

  • Extremely high strength and resistance to deformation;
  • High load capacity with low weight of the beams;
  • Continuous preservation of load-bearing capacity in case of fire;
  • No sweeping;
  • Good mechanical properties;
  • Extremely suitable for visible structures;
  • Each beam is individually wrapped.

Cutting – according to individual customer size.

Additional information about BSH beams

One of the key benefits of the BSH timber beams we offer is its exceptional strength and structural integrity that fully meets all structural requirements. By combining the strength of the individual timber layers, BSH exhibits increased load carrying capacity, making it ideal for bridging large support distances. This strength allows the construction of large-scale structures including bridges, stadiums and commercial buildings (see examples below).

In addition to its strength, the manufacturing process reduces the natural moisture content of the timber, minimising the risk of warping, twisting or shrinking. This stability ensures that the timber BSH maintains its original geometry and dimensions as much as possible, even under changing humidity or temperature conditions, ensuring long-lasting reliability and durability.

In construction, laminated layers can be shaped and sized as needed, allowing architects and designers the freedom to create unique and innovative structures (as opposed to wedge-laminated timber). Whether it is curved beams, arches or complex geometric shapes – BSH offers unparalleled design flexibility, allowing architectural visions once thought impossible to be realised.

Produced through environmentally friendly harvesting that ensures responsible forest management practices, glulam is an environmentally friendly material. The production process itself minimises waste, exploiting the wood’s full potential and reducing overall material consumption. It also has excellent thermal insulation properties, contributing to energy efficiency and reducing carbon emissions in buildings.

Multi-layer glued timber is easy to install. With precision manufacturing and pre-engineered components, construction professionals can quickly and efficiently assemble timber structures, saving time and labor costs.

In summary, BSH is a remarkable building material that combines strength, flexibility, durability and ease of installation. Whether for large-scale investment or unique architectural projects, BSH offers a reliable and sustainable solution that pushes the boundaries of what is possible in modern construction.

A popular choice for the production of laminated beams(BSH) are trees such asDouglas fir (Pseudotsuga), Spruce (Picea), Larch (Larix), Pinus. Other species on request! For example. (Betula), European oak (Quercus robur), Beech (Fagus) ,

As trees grow, they absorb carbon dioxide (CO2) from the atmosphere and store it in their trunks, branches and leaves. When these trees are sustainably harvested and transformed into building materials, they store a significant portion of their carbon content. As a result, the wooden structures act effectively as a CO2 reservoir.

Here are five examples of well-known buildings that have incorporated multi-ply glulam into their design and construction:

1. The Macallan Distillery and Visitor Experience – Craigellachie, Scotland: Completed in 2018, this whisky distillery features an impressive corrugated timber roof structure made from glulam beams. Rogers Stirk Harbour + Partners’ design showcases the natural beauty of the wood while blending harmoniously with the surrounding landscape.

2. T3 (Timber, Technology, Transit) – Minneapolis, USA: T3 is a seven-story office building and one of the tallest modern wood structures in the United States. Completed in 2016, it features a stunning exterior façade made of beams and columns from gulam.

3. Forté Apartments: located in Melbourne, Australia, Forté Apartments was the world’s tallest all-timber apartment building at the time of its completion. Standing at ten storeys, it features a combination of CLT floor and wall panels, along with glulam columns and beams. This project demonstrates the use of solid wood in the residential sector, offering a sustainable and visually appealing living environment.

4. Maggie’s Centre – Oldham, UK: Designed by dRMM Architects, this cancer treatment centre features an innovative use of glulam. The building’s unique roof structure is made of glulam beams that curve and twist to create a visually striking architectural form.
