Fakro DEC-C P2 Electrically Operated Domed Flat Roof Window

Fakro DEC-C P2 Electrically Operated Domed Flat Roof Window

The Fakro DEC-C P2 Electrically Operated Domed Flat Roof Window is a practical choice for bringing more natural daylight and fresh air into rooms beneath flat roofs. Combining a durable domed design with convenient electric operation, it offers a comfortable way to improve ventilation while helping protect the interior from changing weather conditions. Designed for both residential and commercial buildings, the DEC-C P2 features an insulated kerb upstand, safety glazing and a UV-protected polycarbonate dome. Its integrated electric operation makes opening and closing simple, while the built-in rain sensor can automatically close the window when rain is detected.

Excellent Thermal Insulation

The Fakro DEC-C is available with different glazing configurations, including double-glazed P2 and quadruple-glazed U8 options. Depending on the selected model, the window can achieve a U-value from 0.72 to 0.93 W/m²K, helping to reduce heat transfer and maintain a more comfortable indoor environment. The 150mm insulated UPVC kerb upstand adds another layer of thermal protection while providing a sturdy base for installation.

Enhanced Security with P2 Glazing

The window incorporates P2 laminated safety glass, providing additional protection against impact and helping improve security. This makes it suitable for areas where both natural daylight and added protection are important.

Durable UV-Protected Polycarbonate Dome

The raised polycarbonate dome is designed to withstand outdoor conditions while allowing plenty of natural light into the building. UV-resistant coatings on both the inner and outer surfaces help protect the dome against yellowing, fading and degradation caused by prolonged exposure to sunlight.

Convenient Electric Operation

Opening and closing the DEC-C is made easy with its integrated electric servo motor. The motor is positioned within the sash, helping protect it from rain and snow while providing smooth and reliable operation. This makes the window particularly convenient for installations where the roof window may be difficult to reach manually.

Automatic Rain Sensor

For additional peace of mind, the Fakro DEC-C includes a built-in rain sensor. When moisture is detected, the sensor automatically activates the closing function to help prevent rainwater from entering the building.

Flexible Flat Roof Installation

The DEC-C P2 is suitable for flat roof applications with roof pitches from 0° to 15°, giving it flexibility across a range of residential and commercial projects. Its 150mm insulated UPVC kerb upstand also helps simplify installation while providing a durable and thermally efficient base.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
