The Sami people inhabiting the north of Scandinavia are divided by national borders, but wherever the Sami live - in Sweden, Russia, Finland or Norway - it is equally important for them to preserve their cultural identity. In Norway, they also achieved significant political autonomy, and its symbol is the original building of the Sami Parliament, built in the city of Karasjok. Its architectural image is emphasized by the choice of RHEINZINK titanium-zinc material.
Karasjok is located 300 km north of the Arctic Circle. Its 1,500 inhabitants, most of whom are of Sami origin, live in small prefabricated houses. The city is home to a Sami-language radio station, a folk university and the largest Sami library in the world, which is why this recognized center of Sami culture was chosen as the site for the parliament. In 1995, a competition was held for the design of the building of the Sami Parliament of Norway - Sametinget. The winners were the Oslo architects Stein Halvorsen and Christian Sundby. They took into account all the requirements of the customers in their project called "69.3 ° North" and therefore outstripped the remaining 46 participants in the competition. The building, which opened in 2000, combines elements of the traditional Norwegian timber frame construction with other materials, especially zinc.
From afar one can see the “tent” of Sametinget towering over the tops of the pines. The entire complex is visible up close: a semicircular wing of offices encompasses the dining room and library, and a plenary hall is connected to it through a glass passage. Its conical shape is reminiscent of the traditional Sami dwellings - veži. For natural illumination of the interior, part of the cone is glazed, the rest of the walls are sheathed with Siberian larch wood, and accents are placed using RHEINZINK titanium-zinc panels. In total, about 1000 m2 of the façade was clad in RHEINZINK titanium-zinc using the double standing seam technique by Blikkenslager Olaf Hansen AS from Trondheim. The roof of the Sami Parliament, with an area of over 1100 m², was clad with RHEINZINK with prePATINA walzblank surface. Thanks to this, the building has received durable protection from an environmentally friendly material that does not require maintenance and repair throughout its long service life, even in regions like Finnmark, where temperatures drop below 50 ° C.
Since the climate of the region is influenced by both the ocean and the tundra, the temperature can vary significantly - especially in the minus side due to strong winds. However, the roof structure differs little from examples in other northern regions of Norway. The corresponding thermal requirements are 20 cm for walls and 30 cm for roofs.
Below are the technical characteristics of the roof and facade coverings made using the rebate technique.
Roof structure from outside to inside RHEINZINK - double standing seam Metal thickness 0.70 mm Painting length (panel) ~ 7.00 m Painting width (on a cone) 450 mm to 530 mm • Bauder TOP VENT 02 NSK structure mat • Bituminous membrane, glued seams • Lathing 24 mm (in Norway, usually 22 mm is used) • Height of the ventilation gap 8 cm • waterproof and windproof film, seams are glued • insulation 30 cm • vapor barrier membrane, sd- ≧ 100 m • area of the location of communications • Plasterboard plate
This roof structure, standard in Scandinavia and especially in Norway, is the rule for using RHEINZINK in the rebate technique. It should be noted the high skill of the performance of roofing works that required special accuracy and minimal deviation from the design calculation, for example, 8 mm ventilation gap, as well as the joint search for optimal solutions, which was carried out by roofers and designers. The use of a Bauder TOP VENT 02 NSK structural mat over a bituminous membrane is an unusual solution. Enkamat 7008 would be sufficient here - as recommended by RHEINZINK.
Roof technical data To cover 1100 m² of roofing, RHEINZINK rolls with a width of 600 mm and a metal thickness of 0.70 mm were used. On a significant part of this area, cone-shaped paintings with a width of 450 to 530 mm were used, made on a SCHLEBACH machine. The profiles are made using the double standing seam technique, and at the junction with the cornice - a single standing seam.
Facade technical data For facade cladding and finishing, RHEINZINK prePATINA blaugrau material was used, assembled using the corner standing seam technique. In places of bends, hundreds of "crushed" folds were required.
Other arches up to 3 meters high were made using the hinged seam technique with the length of paintings from 2 to 2.5 m. * * * The extreme climatic conditions of Finnmark were a serious challenge for both installers and complex work has become a building, whose architecture, the quality of building materials and their installation have received recognition far beyond the borders of this region.
