Arched roof design
The Peneder arched roof is a fully developed roof system in a modular light-weight design consisting of 610 mm wide separate roof shells arranged side by side. In a double-shell version, arched roofs are one above the other with space in between, which gap is filled with insulation material made of rock wool (Euroclass A1 to ÖNORM EN 13162 or DIN EN 13162). In a standard case, the roof in span direction is formed as a circular arch with radii of curvature from 13 m to 28 m. In longitudinal direction, roof may include any desired number of roof shells arranged sidewise in line with the building project requirements. In the context of special solutions, roof arch radii may vary between 10 m and 60 m with bearing spans up to 120 m with several intermediate bearings.
