Public infrastructure, sports facilities, places of worship, theatres, manufacturing facilities, commercial buildings: glulam structures produced by HBS are at the core of many building projects in Italy and the world.
Glulam is a composite material that combines the natural merits of wood with the advantages of an innovative industrial product. It is made by pressure-gluing timber boards that have been suitably strength-graded for industrial use.
For its glulam products, HBS uses mostly conifers, including fir, larch and pine, but chestnut, oak or other woods can also be used to meet specific requests. After careful seasoning, the timber is cut into planks (the laminates) that are then glued together using melamine or polyurethane adhesives depending on the specific technical and performance requirements, in order to obtain elements of different shapes and sizes.
The length of a glulam beam can exceed 45 meters, a span which is not easily achievable with other building materials, and allows you to build long-span spaces of exceptional architectural and aesthetic value. Glulam beams also have a higher fire resistance than steel or reinforced concrete structures. Although wood is indeed a combustible material, in case of fire, the carbonized surface layer creates a thermal insulation that slows down combustion and allows the structure to continue to perform its load-bearing function for longer, before finally yielding.
