The grain of the laminations runs parallel with the length of the member.
Glulam roof framing.
A glulam is made with multiple layers of solid wood lumber bonded together with high strength adhesive to form a single structural unit.
Introduction proper connection details are important to the structural performance and serviceability of any timber framed struc ture.
Glued laminated timber constitutes an ever increasing percentage of the framing materials used in residential construction.
Much of this growth is attributed to the fact that glulam beams are available from building material dealers and distributors in stock sizes typical widths.
Glulam beams are comprised of structural dimensional wood that is laminated together with structural adhesives.
Glulam beams laid on their flat and used as floor or roof panels are known as glt panels see glue laminated timber panels.
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.
According to structurecraft and the structural timber association the length of glulam panels are only limited by fabrication and shipping constraints.
In large open spaces glulam beams can span more than 100 feet.
Glulam is a stress rated engineered wood beam composed of wood laminations or lams that are bonded together with durable moisture resistant adhesives.
3 1 8 3 1 2 5 1 8 and 6 3 4 inches.
Glulam allows a high degree of prefabrication and long structural spans where necessary but is equally effective for shorter spans.
Glue laminated timber glulam is a structural engineered wood product commonly used for beams and columns in residential and commercial applications.
Glulam columns are straight and dimensionally true making framing an easy task.
Its thermal properties help prevent cold bridging.
Theoretically glulam panels can span any imaginable length and to date roof areas exceeding 100 000 square meters have been constructed using glulam framing.
Because columns are available in long lengths the members do not have to be spliced together as is often necessary with sawn lumber.
One of the greatest advantages of glulam is that it can be manufactured in a wide range of shapes sizes and configu rations.
The term glulam is an abbreviated term that stands for glue laminated timber.
While this is true for solid sawn as well as glued laminated glulam timbers the larger sizes and longer spans made possible with glulam components make the proper detailing of connections even more critical.
In some instances ware house and distribution centers with roof areas exceeding 1 million square feet have been constructed using glulam framing.
Glulam is versatile ranging from simple straight beams to complex curved members.
