Norway houses world’s tallest wooden building Mjösa Tower

WCN Editorial Team 20 Mar 2019 EUROPE BUILDINGS

The Mjösa Tower, the world’s tallest wooden building, has been completed in Brumunddal Norway.

Reaching up to a height of 85.4m, the 18-floor building includes a hotel, private homes and office space.

Metsä Wood’s fast, light and green Kerto LVL (laminated veneer lumber) products were used in the intermediate floor elements of the building.

The Mjösa Tower showcases environmentally friendly thinking in construction.

The design assignment of creating a tall wooden building has been a challenge for Voll Arkitekter architect and partner Øystein Elgsaas.

Elgsaas said: “We want to inspire others to build the same way.”

The dimensions of the elements are much larger even though the structure is similar to conventional buildings.

The structure and facade of the Mjösa Tower are made of wood and the load-bearing structure comprises glulam columns, beams and diagonal members, which is suitable for high-rise buildings.

While the first 10 floors are made of prefabricated wooden elements, the decks on the upper floors are made of concrete, to restrain the building and prevent it from swaying.

The target was to use sustainable, local wood products and local suppliers for the project.

In addition to Norwegian glulam and CLT, Kerto LVL products from Finland have been used in the construction of the building.

Kerto LVL has been used as part of the floor elements manufactured by Moelven Limtre.

Moelven Limtre CEO Rune Abrahamsen said: “As a glulam manufacturer we strive to use our own materials to the largest possible extent.

“However, Kerto LVL is a superior material for the top plate and end beams. Kerto LVL is a lightweight and very straight material thus it guarantees production without any delays.

“The quality of the product is very good.”

Metsä Wood and Moelven have cooperated for years.

Appreciating the quality and FSC certification of the raw material, Abrahamsen said: “Kerto LVL helped us to make Mjösa Tower as sustainable as possible.” He said that he looks forward to new high-rise projects.

With cities continuing to expand globally, the demand for more sustainable construction is also growing, and use of wood has an important role in it.

Part of Metsä Group, Metsä Wood provides environmentally friendly wood products for construction, industrial customers and distributor partners.
