Fakro DSC-C2 P2 1200x1200mm Smoke Ventilation Domed Roof Window Kit

Fakro DSC-C2 P2 1200x1200mm Smoke Ventilation Domed Roof Window Kit

The Fakro DSC-C2 P2 1200x1200mm Smoke Ventilation Domed Roof Window Kit is designed to provide reliable natural smoke and heat extraction while also offering useful everyday ventilation and daylight. As a natural smoke and heat exhaust ventilator (NSHEV), it is suited to commercial and residential buildings where fire safety, thermal performance and a clean appearance are important considerations. Designed in accordance with EN 12101-2, the system uses powered actuators to create a substantial opening during an emergency, helping smoke and hot air escape from the building. Its durable domed construction and insulated frame also provide protection against everyday weather conditions.

Effective Smoke and Heat Extraction

The DSC-C2 P2 features two actuators that lift the sash approximately 50cm parallel to the base. This creates an effective opening to assist with the rapid removal of smoke and heat during an emergency. The system can be operated automatically through its integrated smoke detection and control components, while manual activation is also available when required.

Durable Polycarbonate Dome

The domed roof window is made with a durable polycarbonate dome, designed to withstand outdoor conditions while providing good impact resistance and protection from UV exposure. Its robust construction makes it suitable for flat and low-pitched roof applications where long-term weather resistance is important. The dome also provides a practical way to introduce natural daylight into the space when the smoke ventilation system is not being used for emergency extraction.

Thermal and Acoustic Performance

The DSC-C2 P2 incorporates double glazing with a whole-window U-value of 1.0 W/m²K and a glass U-value of 1.1 W/m²K. This helps limit heat transfer through the roof window and contributes to a more comfortable internal environment. With an acoustic rating of 35dB (-1, -3), the system can also help reduce external noise entering through the roof opening, supporting better everyday acoustic comfort.

Strong Insulated Frame Construction

The window uses a multi-chamber PVC frame mounted on an additional XRD base, giving the complete system a total upstand height of 30cm. This construction provides a sturdy installation base while helping improve insulation and structural stability. The DSC-C2 is suitable for roof pitches between 0° and 15°, making it suitable for a range of flat and low-pitched roof applications.

Discreet and Modern Appearance

When the window is closed, the lifting mechanisms remain hidden to create a neat and unobtrusive appearance. The interior frame is finished in RAL9010 white PVC, providing a clean look that works well with a variety of interior spaces.

Integrated Fire Safety Components

The Fakro DSC-C2 P2 kit includes the key control and safety components required for smoke and heat exhaust operation.

• RZN4404K Control Unit: Provides automatic system control and supports emergency operation.
• RT45 Alarm Push Button / Break Glass: Allows the system to be activated manually when required during an emergency.
• OSD 23 Smoke Sensor: Detects smoke and enables the system to respond automatically.

Optional accessories can also be added for greater everyday functionality. These include an LP1 switch for daily ventilation and a rain sensor that can automatically close the sash when rainfall is detected. The rain sensor is sold separately.
