Metsä Wood’s new construction products provide lower CO2 emissions

According to Metsä Wood, architecture creates an estimated It accounts for 30% of all CO2 emissions and uses up to 50% of the world’s resourcesThe standard use of concrete is cost-effective, but it generates a lot of carbon dioxide.Wood is the best environmental Choose because it has the ability to capture carbon. However, innovation has not yet found a way to make wood products for every application. Therefore, a Finnish company created a hybrid sandwich wall element that replaced half of the required concrete to achieve a more sustainable construction practice.

“About 1 million square meters of specific Finland produces wall elements every year. Their load-bearing core generates 45,000 tons of carbon dioxide emissions. If all concrete walls are replaced with hybrid sandwich wall elements, carbon dioxide emissions will be reduced by 30,000 tons per year and 95,000 tons of carbon will be stored,” explains Jussi Björman, business construction director at Metsä Wood.

A wooden wall with window holes is being built.

Metsä Wood cooperates with a Finnish design company to develop and manufacture this product, which can be used for Residential, Office or industrial multi-storey buildings.

“Mixed sandwich wall elements help increase wood Effectively build more sustainable buildings. This joint development is our effort to support the construction industry,” Björman said.

This innovation combines concrete with Kerto® LVL (Laminated Veneer Wood), which is lighter than concrete and easier to install.Hybrid sandwich walls also provide higher insulation values ​​to improve energy efficiency In this building.

“Because Kerto LVL is a lightweight material, hybrid sandwich wall elements will be produced in the factory and transported to the site faster, and even transported Emissions Will be reduced due to light load. Lightweight elements are also easier to lift,” Björman said.

Kerto® LVL can be used as formwork for joists, beams, trusses, frames, scaffolding, floors, ceilings, concrete works and industrial applications. Metsä Fibre’s new Rauma sawmill is the first construction project to use hybrid sandwich wall elements. Skanska is the main builder of the plant project. These elements will be produced at Lipa-Betoni’s factory in Pieksämäki, Finland It was installed in June.
