Advanced technology and modern building codes are expanding the opportunities for wood in construction.

Wood products offer advantages in terms of material, construction and environmental costs.


Wood is a renewable and responsible choice that helps reduce our environmental footprint.


The first and most obvious benefit of glulam is that its main constituent, timber, grows out of the ground and does not need to be mined and subjected to the high energy demand manufacturing processes that steel and cement require. Of course there are also energy requirements for glulam manufacture in the felling, sawing, transportation, manufacture of the glue etc., but this is still far less than for steel and concrete.


Glulam is often chosen over steel or concrete for its appearance.


Timber is often credited with creating a warm and comfortable feel in a building.


There are many different species and treatments available all with their own character that can be tailored to suit requirements.



Flexibility of shape and size

Beams and Slabs modular in width, height and length

The lamination process is inherently flexible and we can produce glulam in sizes ranging from


Good strength to weight ratio

Timber has a good strength to weight ratio in comparison with steel and concrete. If you consider equivalent beam sizes for the same load bearing capacity in glulam and steel, glulam has approximately 1.5 – 2 times the strength to weight ratio of steel. This means there is a benefit in the buildability of glulam structures – this could be that it becomes possible to manhandle a beam into a roofspace for a loft conversion, or on a larger scale, craning of large prefabricated roof elements becomes feasible. Another advantage is that smaller foundations are needed for a reduced structure weight.


The durability of glulam will depend on its specification. Species of timber, type of glue and preservative type and application are all factors in the durability of glulam. Given the correct specification glulam can be used for the most onerous of conditions. One instance where glulam is chosen for its durability is in swimming pool roofs- this is a articularly corrosive environment with high humidity and chlorine levels and glulam provides a durable low maintenance solution. Glulam is often used for motorway bridges in Scandinavia, designed to last for decades with a minimum of maintenance. More information on the correct specification of glulam for differing environments is given in the Glues and Preservatives section.


Large section timber elements actually perform very well in fires. This is due to the way in which timber chars at a known rate and does not deform like steel. Fire performance of glulam has been the subject of extensive research and structural glulam members can be designed to last a certain period of time in a fire based on the rate at which it chars. Additional fire protective finishes can be used to further increase the fire performance. Glulam can meet building code requirements.
