The darkening flaap for flat roofs
The JET-ALU-DARKENING FLAPS-WD-40 are ideally suited for efficient smoke exhaust in the event of fire. They are utilised in instances where daylight is not needed. The aluminium flap in a sandwich construction method is thermally separated by the stable ventilation frame made from unplasticised PVC and insulated with 40 mm mineral wool. It is therefore completely energy efficient.
The darkening flaps can be utilised in new buildings and refurbishment projects and can be adapted to individual requirements using the extensive JET accessories. An optical adaptation to your project is also trouble free due to the surface area in RAL colour.
The JET-ALU-DARKENING FLAPS-WD-40 are also suitable for daily ventilation. The actuation can be executed either manually, electrically or pneumatically as desired.
