Metsä Wood and its partners have designed a hybrid sandwich wall element, which will renew offsite construction. The innovation combines concrete with Kerto® LVL (laminated veneer lumber). The lighter weight of the hybrid sandwich wall elements proved to be a valuable benefit in the first construction project at Metsä Fibre's Rauma sawmill. Hybrid construction will increase sustainability: Skanska, the constructor of Metsä Fibre's new Rauma sawmill, has set up ambitious goal for itself as it aims to be carbon neutral globally by 2045. This has led the company to provide low-carbon or carbon neutral life-time solutions to its customers. Romo foresees that wood construction will increase over the next couple of years, and there is already now more demand. The forms of wood construction and their impact on business and customer wishes are under review. The element productions easy: The production of the new hybrid sandwich wall elements, which are used in the sawmill's log sorting building, went as planned at the precast element manufacturer Lipa-Betoni's factory. This is the first time the factory produced hybrid wall elements. In the production of a hybrid sandwich wall element, a Kerto LVL panel forms the load-bearing core. This is followed by an insulation layer and reinforced concrete facade. Smoothinstallation of hybrid sandwich elements at the construction site: The installation of the hybrid sandwich wall elements for the first floor, 100 m, of the building took five hours.
