Strength graded and ready finished glued timber.
Characteristics of glued laminated timber.
Many different species of lumber can be used to produce glued laminated timber.
Glued timber is a wood product which does not fulfil the laminated timber standards but is made by gluing two or more items of sawn goods together.
Glulam can also be produced in curved shapes offering extensive design flexibility.
In this study three layered cross laminated timber clt manufactured from acacia mangium wood panels were developed by using two different types of adhesives namely phenol resorcinol formaldehyde prf and one component polyurethane pur.
Dry lumber and characteristics unique to the glued laminated timber manufactur ing process such as being able to vary the grade of lumber throughout the depth of the member.
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.
Such products are used as they are in loadbearing construction and as blanks for various wood products such as window frames laminated logs etc.
Glued laminated timber glulam is composed of several layers of dimensional timber glued together with moisture resistant adhesives creating a large strong structural member that can be used as vertical columns or horizontal beams.
