Self-supporting & indefinitely extendible
Arched roof

Whether single or double shelled, Peneder arched roofs feature self-supporting span width up to 25 meters. Small to large areas can be quickly sheltered thereby. With additional steel or concrete substructure and several arches, the roof can be indefinitely extended lengthwise. Areas of 10,000 m2 can be readily sheltered.


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.

Light-flooded and safe

Transparent or opal light shells from polycarbonate enable, particularly with large roof areas, an optimum lighting solution throughout the space width, thus creating friendly, natural light-flooded premises. In addition, standard light domes or hood fans can be built in.

The Peneder arched roof meets stringent fire protection requirements (up to REI 180) and offers an efficient noise and sound insulation (up to Rw 50 db). Whether thermal insulation or humidity protection, airtightness or ventilation, the Peneder arched roof meets the most stringent requirements and is maintenance-free.
