More comfort and energy efficiency for flat roofs

Irrespective of whether you are looking for energy-efficient daylight for a new building or refurbishment project - the JET-TOP-90-COMFORT is always the optimum solution. It does not just provide complete transparency for a high daylight input, rather is also thereby very well thermally insulated.

In applications as a fixed or ventable flat roof light dome, it can also be utilised for ventilation or as an SHEV system for effective smoke exhaust in the event of a fire. The JET-TOP-90-COMFORT can therefore be optimally adapted to all individual requirements.

This freedom of design is also complemented by the wide range of accessories. The JET-TOP-90-COMFORT can, for example, be supplied with the SUPER-TOP and HAIL-STOP design structures and therefore provides maximum safety against hail and vandalism.
