UPM's birch plywood and wood plastic composite in on creating the atmosphere of the Piano pavilion in Lahti

WISA birch plywoods and UPM's novelty product UPM ProFi Deck from the Lahti mill are among the most visible elements in the Piano pavilion built in Lahti harbour. ”UPM wanted to participate in creating a prominent building containing new, innovative solutions located in a vantage point in Lahti," justifies Arto Juvonen, Senior Vice President, Plywood, the participation of UPM in this project.

According to Juvonen, a concrete project visible for the public significantly contributes to the target-orientedness of UPM's own R&D function. A similar project was years ago the Sibelius Hall next door, where UPM's plywoods play a prominent role in interior lining and façade.

”A project like Piano pavilion offers us an opportunity to work together with top class architects. Combining top class architecture and UPM's know-how in products and wood structures results in unparalleled solutions."

Also Director Markku Koivisto from UPM ProFi business unit is satisfied with the cooperation. ”Piano pavilion is an excellent example of modern wood construction and the many opportunities that wood as raw material can offer. It feels great to have a hand in this and tell people about innovations and the power of this field to regenerate."

Demanding machinings in birch plywood

Nearly all the interior surfaces visible in the Piano pavilion, such as ceiling, walls and service desks, have been lined with WISA birch plywood. More birch plywood can be seen outside, underneath the eaves of the terrace. Although the birch plywood used for the pavilion is 12 mm standard plywood, the machinings are far from standard. The interior is combined from about 90 pieces of panels, in nearly all of which the machining differs from the others.

Acoustics combined with esthetics

Perforations serve the acoustics, explains Mr. Anders Adlercreutz, Architect SAFA, from the architects' office A-Konsultit Oy, Helsinki. ”Perforation as such dampens the noise in the restaurant but the variation in hole sizes serves to the esthetics," states Adlercreutz.

Adlercreutz has acted as the co-operation architect for this project, co-ordinating the planning in Finland and adapting it to local conditions. ”The original plan made by the Swede Gert Wingård has partly been adapted to suit the products of the co-operation partners," says Adlercreutz.

Durable and good-looking deckings made from recycled material

The terrace of the Piano pavilion is made from new wood plastic composite deckings, UPM ProFi Deck. A special colour, Marble white, was created according to the wishes of the architect. ”In our opinion the product is very good," says Adlercreutz.

UPM ProFi has also been used by the Japanese architect Shigeru Ban, known for the innovative use of recycled materials, who used UPM ProFi as material for the Artek pavilion at Milano design fair.

UPM ProFi is a new, innovative material, made mainly from surplus paper and plastic left over from the production of self-adhesive label materials. The physical properties of UPM ProFi Deck are ideally suited for public spaces, because it is highly resistant against wear and moisture and requires no other maintenance than washing. The material is also safe in use, because it does not contain any harmful chemicals nor is it slippery when wet.
