Glue Laminated Beams

Glue-laminated (glulam) beams are available in a variety of different timbers as they use dry smaller section source material – Ash, Chestnut, Oak, Douglas Fir and spruce are all available. They are planed, straight and clean lined, have very few surface anomalies, are extremely stable and wont shrink, crack or shake, and they can be easily treated with decorative finishes .

Carpenter Oak have completed several projects using this material and are excited by the alternatives it offers.

Glulam beams are available in a huge lengths and sections. Engineers tend to love them as they are very uniform, stable and predictable which suits their structural analysis techniques. For this reason they are often used in large scale building projects such as public buildings. They suit modern, contemporary buildings but are often referred to as the timber equivalent of steel beams.

Glulams are excellent materials dependent on your project, design and styling ideals. Here are some of the Pros and Cons to consider before choosing to use Glulam:
  • They are not suitable for exterior use.
  • It is very stable. Glulam has a moisture content of typically 8%-12% (compared to 60%-80% within Green Oak). The moisture is a indicator of how much you can expect the timber to move (shrinkage, twisting and splitting (shakes)) through the drying out process.
  • They can be several times more expensive  and require additional workshop space.
  • The timber doesn't need any cleaning (in theory) as the finished surface is what is delivered to our framing yard but as a consequence requires special care while handling to avoid marking the timber.
  • Large clear spans are easily achieved with glulam beams
  • You can order exact shapes, curves, radii and specific sections
  • You can achieve a very crisp and sharp look timber frame using glulam. See the Greywings Case study
  • The manufacturing process for bespoke beams is longer than other materials, meaning significant lead-in times
  • The glulam can be jointed using mortice and tenon, hidden steel brackets or feature stainless steel connections.
