Stylish space

The first facilities for the employees of the construction site of Metsä Group’s bioproduct mill have now been completed in the Palomäki accommodation village in Äänekoski, Finland. The design of the accommodation facilities makes use of Kerto-Q panels in a unique way.

Two accommodation units for a total of around 100 people have now been completed on the Palomäki field near the construction site of Metsä Group’s bioproduct mill. The accommodation village will be expanded according to need, with facilities for a maximum of 400 people. The first residents have already moved in.

The construction of the next-generation bioproduct mill is progressing rapidly in Äänekoski in central Finland. The construction site currently employs 750 people, and the number of employees will increase up to 2,500 people towards the end of the year.

“We wouldn’t have been able to find suitable accommodation for everyone in Äänekoski or the surrounding area. That’s why we decided to build temporary accommodation facilities for up to 400 people near the construction site,” says Juha Pesonen, Project Coordinator of the bioproduct mill at Metsä Fibre.

Metsä Fibre, part of Metsä Group, leased the lot from the municipality of Äänekoski. It is located around one kilometre from the bioproduct mill and around one kilometre from the centre of the town. The developer is Rental Store Finland, a company specialising in providing temporary accommodation.

“Functional, reasonably priced accommodation facilities near the construction site and the centre of the town enable the construction project to run smoothly. For this reason, we want to actively promote the construction and marketing of such facilities in cooperation with other operators,” says Pesonen.

The accommodation facilities are intended solely for the employees of the bioproduct mill construction site.

Stylish, flexible accommodation facilities

The accommodation facilities in Äänekoski consist of residential modules that make use of Metsä Wood’s Kerto-Q panels in an entirely new way. The modules will be manufactured and erected by Termater Oy, a company based in Veteli, Finland. On the outside, the stylish two-storey buildings look like new terraced houses.

“The design is intended to make the buildings not only functional but also impressive. The timber cladding and its different tones lend a nice appearance to the houses,” says Harri Kuusiluoma, CEO of Rental Store Finland.

His family business is preparing to build up to eight houses in Äänekoski, each for 48 people.

“This is a new type of project for us, and its scope is significant. When they are no longer needed in Äänekoski, the buildings will be moved elsewhere for use as hotel or other accommodation. This was considered when determining the height of the rooms, among other aspects. The room height allows for the retrofitting of technical building systems.”

According to Kuusiluoma, new innovations will continue to be created around Kerto® LVL.

“For example, we are developing movable elements for creating spaces. Kerto will play a key role in these elements.”

Kerto-Q serves as a load-bearing structure

Each building consists of 26 modules, which are manufactured in Veteli and transported to Äänekoski. According to Tomas Luoma, Product Manager at Termater, the load-bearing structure of this entirely new type of element consists of Metsä Wood’s Kerto-Q panels.

“The wall element consists of 51-millimetre Kerto-Q panels and 15-millimetre OSB panels on the exterior surface. Termater uses its unique technology to cast a 150-millimetre layer of polyurethane insulation between the panels. The exterior of the element is clad with horizontal panels,” Luoma explains.

The polyurethane insulation sticks firmly to the Kerto panel, and the strength properties of the panel ensure that the wall elements stay straight.

The floor and ceiling elements contain 27-millimetre Kerto-Q panels. The internal walls in the accommodation rooms consist of Kerto panel with a high-quality surface veneer.

“Painted Kerto is a stylish internal wall. No other surface treatments will be needed,” says Luoma.

A cost-effective and energy-efficient solution

According to Hannu Veikkola, Domestic Sales Specialist at Metsä Wood, the element solution developed by Termater makes excellent use of the best properties of Kerto-Q.

“The load-bearing wall structure can be implemented cost-effectively, as the elements can be built of sheets 2.5 metres high and up to 20 metres long.”

The Kerto panels for Äänekoski will be manufactured at Metsä Wood’s mill in Punkaharju. “The 51-millimetre sheet consists of seventeen spruce veneers. Around one-fifth of the veneers are cross-bonded, which gives the sheet very good transverse strength.

When combined with the polyurethane insulation developed by Termater, Kerto-Q prevents thermal bridges from being formed in wall structures, thereby reducing thermal loss. For this reason, the accommodation buildings clearly meet and exceed the requirements for permanent dwellings with regard to their wall elements.

“In addition to its rigidity and strength, Kerto-Q also has an excellent fire classification, which enables it to be used in the construction of wooden apartment buildings, for example,” says Veikkola.
