Glulam, or glued laminated timber, is an engineered wood product made by bonding together layers of dimensional lumber with durable adhesives. This process allows for the creation of large, strong beams and arches that can be used in various construction applications, such as bridges, buildings, and sports arenas. One of the key advantages of glulam is its ability to span long distances without the need for intermediate supports, making it ideal for open spaces. Additionally, it is a sustainable material, as it utilizes smaller pieces of wood, reducing waste and promoting responsible forestry practices.
