Strength for strength, a laminated timber beam is one-sixth of the weight of a reinforced concrete beam and two-thirds the weight of a steel beam.
A direct cost comparison shows Moelven laminated timber to be competitive with other structural materials and the lower weight of Moelven Glulam leads to savings on foundations, transport and erection.
Timber is well known to be easy to erect and handle. Fixings are easier and less sophisticated than to other structural materials.
Moelven Glulam will generally be factory tailored to meet your specification. But for the more straightforward applications, there is a range of members of standard cross section. These are available on short delivery.
Moelven Glulam has a high resistance to fire and it behaves predictably under fire conditions. In Sweden, where the fire regulations are notoriously strict, Moelven Glulam beams enjoy lower fire insurance premiums than steelwork.
Correctly dried timber is very durable - particularly in the large sections typical of Glulam. If extra durability is needed, the members can be supplied treated with preservative.
The natural appearance of Glulam is sufficiently attractive to need no cladding to make it presentable - indeed, used as exposed beams, it adds to the aesthetic appeal of a structure.
Laminated timber can be used for roof and floor beams, columns, and rafters in almost any type of structure.
Glue laminated timber - Performance requirements and minimum production requirements meets the requirements of British Standard BS EN 386:2001, BS EN 391:2002 & BS EN 392:1995. 'The Specification for Glued Laminated Timber Structural Members'.
The capacity for custom made structural member
Moelven have four main production units. One in Sweden and two in Norway. Together they produce in excess of 80,000m³ of glulam.
The Moelven range of standard stock section sizes are all available "off the shelf" from Moelven LTS.
Since wood is a renewable resource, Moelven Glulam is an ecologically attractive alternative to steel and concrete; furthermore, it takes ten times more energy to make a steel beam, for example, than to make an equivalent laminated timber beam.
