Kiln drying
The milled timber for Timberbond Glulam is dried from green to a moisture
content of 12 -16 percent by volume in specifically designed kilns.
Stress
grading
As Timberbond glulam is an engineered product and therefore has high demands
placed upon it, the grade of timber that is used has to be very high.
As such, all the timber is graded visually and often mechanically as to
optimise and ensure the performance of the beam.
Finger joining
Timberbond Glulam ensures maximum material recovery by finger jointing
the individually laminated layers into the required length. The use of
finger jointing laminates ensures maximum strength in the final product
and eliminates many possible defects from the product. Once individual
laminates are jointed to the desired length they are planed smooth ready
for gluing and pressing.
Pressing
A mechanical press is used to press Timberbond Glulam to the final shape
and cross section. The flexibility of the presses available to Timberbond
Glulam ensures that a wide variety of shapes can be produced. Prior to
assembly in the press the contact surfaces of individual laminates are
coated with a measured quantity of glue using mechanical glue spreading
systems. The glues used in the pressing process are chosen for specific
properties that address the requirements of end uses. When laminates are
in position in the press they are brought under pressure and held for
the initial curing period of the chosen glue.
Planning
Specialist planing machine is used at the completion of pressing Timberbond
Glulam plan to the final design size. Special handling equipment and extra
wide machines have been designed to handle the complex sizes available.
On completion of planing Timberbond Glulam is sanded and if required sealed
or stained ready for packing and shipment to the client's site.
Instalation
Timberbond Glulam can be installed using common construction techniques
and equipment. The use of standard carpentry skills and the pre-assembly
of roof sections make for speedy erection and consequent cost savings
