Flat roof windows type C and type F

Designed for thermal performance

Due to their special design, FAKRO flat roof windows provide excellent insulation parameters. Windows are available with a single, double and triple chamber glazing units. Additionally, the type C flat roof windows are available with the dome.

The type F flat roof window is available with a triple chamber DU8 glazing unit. Heat transfer coefficient for this window is U=0.64 W/m²K according to EN 14351-1 which makes the window suitable for use in energy-efficient and passive buildings.

The type C flat roof window with a triple chamber, passive U8 (VSG) glazing unit features heat transfer coefficient U=0.55 W/m²K according to EN 1873 (for a size 120x120cm). This is an excellent parameter relating to the entire window (frame with the sash and dome). This type of roof window is designed with features that can support building security and resistance to unauthorised access

High safety

The DMF DU6 Secure, DXF DU6 Secure, DMC P4 Secure and DXC P4 Secure flat roof windows comply with European 2nd anti-burglary class RC 2 N as per EN 1627. In addition, flat roof windows are distinguished with the highest impact resistance class SB 1200 according to EN 1873. Installation of this type of windows in the roof considerably enhances safety and anti-burglary resistance of the building.

Ample natural light

The purpose of the window is to provide natural light to interiors under the flat roof. This solution is designed to help bring more natural daylight into rooms under flat roofs.

Non-standard sizes

In addition to standard sizes, the type F window can be manufactured in non-standard size (in the range between 60x60cm - 120x220cm). Thermal insulation standards of buildings have been significantly increased and old skylights in flat roofs do not meet current requirements in this scope. Designed to support the thermal insulation performance of the building envelope. Taking advantage of such opportunity gives high flexibility when designing buildings or when carrying out their renovation.

Accessories and control

Compatible internal and external accessories are available for flat roof windows and may help adapt the product to individual functional and aesthetic preferences. Awning blinds can help limit the effects of solar heat gain, while internal accessories may assist in regulating daylight and supporting interior styling choices.

Electric flat roof windows are available with wireless Z-Wave control. The actuator is positioned within the sash design. Selected models feature a rain sensor designed to automatically trigger window closing when rain is detected.

• the frame of the flat roof window is manufactured with multi-chamber PVC profiles.

• the internal surface of the frame is white (RAL 9010).

• the material from which profiles are made have a high resistance against acids and very low moisture absorption, therefore the window can be installed in every room.

• the profiles used in Type C and Type F flat roof windows are filled with insulating material, which is designed to support the product’s thermal insulation performance. 

• the specially profiled covering material under the frame drip cap facilitates the finishing of the window connection with the roofing material.

The servo-motor in electrically opened windows is positioned in the sash and is protected against adverse weather conditions such as rain and snow.
This supports trouble free operation of the servo-motor and all control elements.

The electrically operated windows (type F and type C) have a built-in sensor that automatically activates the sash closing function when it rains.
