Glue laminated construction glulam products are large manufactured structural products used in commercial and residential applications.
Blued laminated construction.
Glued laminated timber also abbreviated glulam is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable moisture resistant structural adhesives.
When glued with industrial adhesives usually melamine or polyurethane resin.
This engineered wood product is composed of multiple laminations of kiln dried end.
Because of the laminated construction technique beam depth can be supplied much larger than solid timbers which are normally limited to 16 20 inches of depth with beams up to 60 deep having been manufactured.
The idea of laminating lumber with glue for use as beams was originally conceived on job sites in europe over 100 years ago.
Other common engineered wood products include plywood oriented strandboard osb and laminated veneer lumber lvl.
Glue laminated trusses glulam truss beam thickness is normally 3 7 but can be larger.
A glue laminated timber is an engineered wood product meaning it is made from wood but is machined and assembled to precise specifications to create a predictable dimensionally stable building material.
In north america the material providing the laminations is termed laminating stock or lamstock.
