Why do we need glulam?
When a glulam is used, it’s often because the timber is needed for a specific span, camber, or tension specification. Notching or drilling can compromise the integrity and required strength of the beam since those modifications alter the laminations and specific lay up of the engineered beam. In certain cases, it may be fine to alter the member in this way. We can’t possibly address every scenario in this article, so let’s look at the basics:

ABOUT GLULAM
Glulam or laminated timber is an engineered wood that is stronger than steel and can carry more load than a same-sized beam of regular timber. Glulam is made from multiple layers or laminates of structural wood that are pasted on top on one another using adhesives. These are moisture-resistant to prevent water damage.
ADVANTAGE AND BENEFITS OF GLULAM
Due to the structural strength and stability offered by pasting several layers together, glulam is much stronger than regular, solid timber.
