Continuous rooflights or skylight domes bring daylight into industrial and commercial buildings. Daylight streaming in through appropriate roof openings also reduces operating costs. At the same time, continuous rooflights and skylight domes can support the ventilation of the building and fulfil fire protection functions. In order to make these functions available in industrial and commercial buildings in a high-quality form, frame profiles as load-bearing substructures must fulfil the functional requirements of commercial buildings.
