After several years of a problem with the roof on Nordichallen in Sundsvall, Sweden, a large air dome has now taken place over the building.
In order to eliminate constant snow issues on Nordichallen, which has been a big problem for several years, the municipality decided to install a lifted balloon roof, known as air dome.
This means that snow will not remain on the roof surface. The shape of the airdome and totally flat surface ensure that the snow slides from the air dome.
