JET Doppelklappe

JET Continuous Rooflight Double Flaps

Can be utilised both as SHEV flaps as well as ventilation flaps

Irrespective of whether you are looking for an SHEV flap, a ventilation flap or both together for your JET-VARIO-NORM and JET-VARIO-THERM continuous rooflights - You are making the right selection with the JET continuous rooflight double flaps.

Smoke, heat and toxic gases are dissipated via the 95° opened double flaps as an SHEV device. This means that the layer near the floor remains smoke-free and the escape and rescue routes can be passed along safely. All devices are tested and certified according to DIN EN 12101-2 for maximum safety.

If you would also like to utilise the double flaps for natural ventilation, then they can easily be equipped with the optionally available accessories. Depending on the specification, the opening can be actuated electrically (230 V/AC or 24 V/DC) or pneumatically. Additional accessories such as wind/rain alarm devices and central closing control system with timer complete our range for you - for maximum safety with maximum comfort.
