JET TOP-90 Komfort

TOP-90 comfort dome rooflight

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 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 rigid or ventable flat roof light dome, it can also be utilised for ventilation or as a SHEV device for effective smoke extraction in the event of a fire. The 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 TOP-90 comfort can, for example, be supplied with the SUPER-TOP and HAILSTOP design structures and therefore provides maximum safety against hail and vandalism.
