Antinkangas School Center
The largest single construction in the city of Raahe, the Antinkangas multipurpose school building is a fascinating project. This massive building has a total of 7,545 m² of space including school facilities for 440 students and daycare facilities for 150 children. In addition, the center offers youth facilities and a large exercise hall that can accommodate up to 1,000 people.
The goal for the design was to serve multiple user groups, and it was important that the building could be divided into sections that are safe and pleasant to use, even for the smallest members of the community. There was also a request from the municipality to design and build a “common living room” for all residents of Raahe.
A key challenge was to find an exterior solution that would create lightness despite the building’s massive size. Avario Architects decided to combine cladding panels with four different widths to create variety while simultaneously highlighting the various elements of the building. In addition, a variety of colors was used to create a strong visual effect and help visitors to navigate the center.
A total of 40,000 meters of exterior cladding panels were divided into four widths – 95, 120, 170 and 220 mm – and installed using a carefully designed pattern. The exterior of the polygonal multi-story building is lined with Siparila TOPCOAT-S fire-retardant cladding panels. Siparila’s fire-retardant cladding offers the highest Reaction to Fire classification for wooden construction products – B-s1, d0. This allows for the use of wood in buildings with the most demanding fire class such as schools and nursing homes. Fire-retardant cladding slows down the combustion of the material in the event of a fire, giving more time for evacuation and fire extinguishing.
Siparila’s fire-retardant cladding panels also carry the CE label, which ensures the product’s quality and fire-resistance properties. The CE marking demonstrates that the surface treatment agent used for fire protection has been tested and approved by an authorized research institute. TOPCOAT cladding panels are pre-painted, with a convenient concealed attachment that allows for a nail-free look. When installed on site, the visible seams of the panels can be hidden to create a smooth, uniform façade.
