JET combi dome rooflight

Roof exit and SHEV combined in one system

The JET combi dome rooflight combines the comfort of a roof exit with the safety of preventive fire protection in one system and has already proven itself many times in practice. It enables you to fulfil the requirements of the LBO for effective stairwell smoke exhaust, and also has an integrated ventilation function.

The electrically operated roof exit device opens conveniently at the touch of a button. The system is also optionally available with a ladder holder or a grating with ladder holder.

The combi dome rooflight simultaneously provides a large ventilation cross-section for infinitely variable, natural ventilation as well as a supplementary OPEN/CLOSE function.
