Irrespective of matter whether you want to utilise the JET continuous rooflight flaps as SHEV flaps for effective smoke and heat ventilation or as pure ventilation flaps for daily ventilation - our products are optimally prepared for the corresponding requirements. The combination of both functions (SHEV + ventilation) is also possible without any problems.
You can hereby select between full flaps, side flaps, cross beam flaps, single flaps or double flaps. The continuous rooflight flaps must be equipped with appropriate opening systems for daily ventilation - either as electrically or pneumatically actuated. Control is executed via a central closing control system with timer and based on the data supplied by the associated wind/rain alarm device for particular comfort.
We implement the optimum flap system depending on the continuous rooflight order width and according to the individual requirements. All the devices are tested and certified as NSHEV pursuant to the European requirements for natural smoke and heat exhaust ventilators according to DIN EN 12101-2.
