Polar Sea Cathedral


Project Name Polar Sea Cathedral Location Tromsø, Norway Year 1965
Contractor Ing. F. Selmer Architect Jan Inge Hovig Owner/Builder Tromsøysund Municipality

General Description:

Situated in the city of Tromsø and surrounded by the breath-taking Tromsdalstinden mountains, the Polar Sea Cathedral is one of the most famous tourist attractions in northern Norway. The cathedral was constructed in the mid-sixties and the special roof and main structure consists of lightweight concrete.

Why Expanded Clay:

The church comprises a main 740-seat nave with a 90-seat chapel in a lower level. The architectural shapes derived from the analysis of the site conditions and from the need to keep a constant and uninterrupted relation between interior spaces and landscaping.

Key benefits:

The most outstanding building feature is the inclined roof consisting of lightweight concrete sections, which enabled to meet important insulation requirements and to reduce the structure weight. The use of lightweight concrete allowed reducing the structural load about 50% as compared with a conventional rib structure with inner insulation. It was obtained a high degree of insulation with no thermal bridges, involving considerable cost savings.
