VERSATILE FACILITIES PROVIDE SERVICES TO A DISTRICT WITH 40,000 INHABITANTS

The building is interesting both visually and functionally, and it takes up the entire plot reserved for it. The entrances, rooftop terraces and external staircases of the three-story building bring the surrounding cityscape to life.

The facades feature bricks of different shades mortared together using so-called “brushmaster’s joints”, where the leftover mortar is spread on the face of the brick, as well as specially profiled, fire protected spruce panels.and portable temporary facility.

FIRE PROTECTED TIMBER CLADDING MAKES THE FACADES STAND OUT

Warm-toned oak has been used in the upper secondary school’s interior cladding. The same tone was also used in the sculpture-like articulation and entrances of the facades. They were clad with blind-nailed spruce panels, manufactured and fire protected by Nerkoo’s Planing Mill.

 The panels were fire protected with a translucent NT DECO fire retardant. The panel walls with hidden grooves create an impression of a narrow lathing, emphasizing the desired small scale of the building.

“Products that comply with fire class B-s1 d0 must be used in the facades of public buildings. We searched for and found a flame retardant with the right tone for the panels, thanks to the models implemented together with Nordtreat and Nerkoo’s Planing Mill. We spent enough time searching for the right profile and color and manufacturing the fire protected products. This can be seen in the end result, which was a success.”
