Characteristics of glued laminated timber.
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.
It is the basic material in manufacturing glued laminated timber.
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.
Many different species of lumber can be used to produce glued laminated timber.
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.
Cross section structure of glulam.
Glue laminated timber glulam is a structural engineered wood product commonly used for beams and columns in residential and commercial applications.
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.
Glulam can also be produced in curved shapes offering extensive design flexibility.
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.
Glued laminated timber made of beech and hybrid beams made of beech spruce.
The aim of this work is to investigate and compare the physical and mechanical properties of clt manufactured using prf and pur adhesives.

Laminated timber according to din en 14080 2013.
In addition a wide range of grades of both visually graded and mechanically.
Wood is one of the oldest construction materials.
Glulam beams manufactured by apa members are certified with the apa trademark.
It is a highly visible form of mass timber in contemporary projects with long spans framing signature designs left exposed to take advantage of wood s natural aesthetic.
Certification of the product an the producer.
In north america the material providing the laminations is termed laminating stock or lamstock.
The mark signifies that the manufacturer is committed to a rigorous program of quality verification and testing and that products are manufactured in conformance with ansi standard a190 1 standard for wood products structural glued laminated timber.
Strength graded and ready finished glued timber.
The functional properties of glulam structures are such that wood as a traditional material allows for new construction challenges and imposes itself as one of the construction materials of the future.
