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.
What is laminated bamboo lumber and bamboo glulam what is the basic difference.
In north america the material providing the laminations is termed laminating stock or lamstock.
And is approximately 80 for bamboo scrimber and 30 for laminated bamboo van der lugt 2008.
A glulam is made with multiple layers of solid wood lumber bonded together with high strength adhesive to form a single structural unit.
The glulam product guide form x440 describes apa trademarked glulam addresses important design considerations and includes a specification guide it also highlights some of the many applications where glulam is used in construction.
With construction advantages including higher design values improved overall performance and cost savings glulam is the product of choice for projects ranging from residential beams and headers to commercial.
Laminated composites plywood and veneered wood are all laminated wood products.
The term glulam is an abbreviated term that stands for glue laminated timber.
Glulam has been shown to be as strong as steel with greater strength and stability than similarly sized standard dimensional lumber.
Available sizes strengths and stiffnesses are similar to psl.
They all have a core with a coating or layer on both sides.
The difference is how they re made.
Psl beams are generally more expensive than glulam lsl or lvl beams.
Psl beams can be stained or finished where an aesthetically pleasing exposed application is desired.
Download the glued laminated beam design tables form s475 provide recommended preliminary design loads for two of the most common glulam.
Figure 3 details the manufacturing process and illustrates the difference between the two products with bamboo scrimber primarily.
In comparison the material efficiency of glulam production in the usa is approximately 82 puettmann and wilson 2006.
Builders often refer collectively to all types of laminated beams or other laminated structural wood materials as glulams.
The difference in laminated wood products typically is the core of the material.
