Glulam is workable
Since glulam is glued together using thin flexible lamellas it can easily be manufactured in curved shapes, which is normally expensive in other types of structural materials. This ability gives huge potential for the manufacture of arches and portal frames. 

With these optimum structural shapes it is possible to use less wood and achieve simple architectural solutions.

Even in apparently straight glulam beams with a constant cross section the flexibilityof the glulam is used to pre-camber the beam. Beams are glued with the required camber, simply by putting some moulded pieces into the jig. It is an advantage which is not especially expensive, but it secures a pitched roof or an elastic look.

 

Glulam is Adjustable

Glulam beams can be manufactured to the exact dimensions required. Normally, however, it is an advantage to choose the cross section of the glulam beam, so that it can be formed using standard thickness lamellas.

The cross section can be advantageously adjusted as required. For example, increased height where there is large load (large moment). This provides the possibility of creating

a pitch on the roof surface, whilst keeping a level ceiling. for instance single 

pitched beams and double pitched beams.
