Fakro DEC-C U8 Electrically Operated Domed Flat Roof Window

Fakro DEC-C U8 Electrically Operated Domed Flat Roof Window

The Fakro DEC-C U8 Electrically Operated Domed Flat Roof Window is designed to bring more natural daylight and convenient ventilation into rooms beneath flat roofs. Combining modern electric operation with strong thermal performance, it provides a practical solution for residential and commercial buildings where comfort, security and ease of use are important. The domed design allows natural light to enter the room while helping protect the window from changing weather conditions. With an integrated electric motor and automatic rain sensor, the DEC-C U8 can be operated conveniently while also providing added protection when the weather changes.

High Thermal Performance with U8 Glazing

The U8 quadruple-glazed configuration is designed to provide excellent thermal insulation, helping reduce heat transfer through the roof window and maintain a more comfortable indoor environment. Depending on the selected configuration, the DEC-C range offers U-values from 0.72 to 0.93 W/m²K. The window is supplied with a 150mm insulated UPVC kerb upstand, providing a thermally efficient base while also helping simplify installation.

Safety and Security

The Fakro DEC-C U8 incorporates P2 laminated safety glass, offering added protection against impact and helping improve security. This makes it a suitable option for both domestic and commercial environments where natural daylight needs to be combined with additional protection.

Durable UV-Protected Polycarbonate Dome

The polycarbonate dome is built to withstand exposure to outdoor conditions while allowing plenty of daylight into the room. UV-resistant coatings on both the inner and outer surfaces help protect the dome against the effects of prolonged sunlight exposure, supporting long-term clarity and durability.

Easy Electric Operation

The integrated electric servo motor makes opening and closing the roof window simple and convenient. The motor is housed within the sash, helping protect it from rain and snow while providing reliable operation. Electric operation is particularly useful where the roof window is installed in a position that is difficult to reach manually, allowing ventilation to be controlled with greater ease.

Automatic Rain Protection

The DEC-C U8 includes a built-in rain sensor that detects moisture and automatically closes the window when rain is detected. This provides added convenience and helps reduce the risk of rainwater entering the building if the window is left open.

Suitable for Flat Roofs

The Fakro DEC-C U8 is suitable for flat roof installations with pitches between 0° and 15°. This makes it a flexible choice for a variety of residential and commercial flat roof projects. The insulated UPVC kerb upstand provides a stable installation base while contributing to the overall thermal performance of the window.

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.
