For highest safety in preventive fire protection

The JET-ALU-DARKENING FLAP-WD-80 can be ideally used to efficiently dissipate toxic smoke fumes in case of fire. Especially in buildings where daylight is not necessary or not desired, such as for example in cinemas.

They comprise aluminium flaps in a sandwich construction method. They are thermally separated by the stable ventilation frame made from unplasticised PVC and insulated with 80 mm mineral wool. This also makes them particularly energy-efficient.

Irrespective of whether in new buildings or for use in refurbishment projects - the darkening flaps can always be adapted and individualised to the given requirements due to the comprehensive JET accessories. The optional coating of the surface area in RAL colour also contributes to this.

The JET-ALU-DARKENING FLAP-WD-80 is also suitable for aeration and ventilation. This can be executed either electrically, pneumatically or manually.
