liimapuujärjestelmien

Liimapuujärjestelmät, known in English as glued laminated timber systems or glulam systems, are engineered wood products used in construction. They are created by bonding together dimensioned pieces of softwood lumber with durable, weather-resistant adhesives. These individual laminations are typically 45 mm thick or less and are arranged parallel to one another and to the length of the member. The wood grain in each lamination runs in the same direction, which allows for the creation of strong and stable structural elements.

The manufacturing process for liimapuujärjestelmät involves careful selection of timber, followed by drying to a specific moisture content. The laminations are then glued together under pressure and heat or at room temperature, depending on the adhesive used. This process results in members that are stronger, stiffer, and more dimensionally stable than solid timber of equivalent size. Liimapuujärjestelmät can be produced in a wide range of shapes and sizes, including straight beams, curved beams, and complex three-dimensional structures.

These systems are commonly used for beams, columns, arches, and trusses in various building types, from residential homes to large public structures like bridges and sports arenas. Their advantages include high strength-to-weight ratio, renewable resource utilization, good fire resistance compared to steel, and aesthetic appeal. The production of liimapuujärjestelmät is a standardized industrial process, ensuring consistent quality and performance.
