Although there are huge benefits to having natural light, it is not always possible to install standard vertical windows in a building with a flat roof. Every room should provide a source of natural light for the occupants to feel comfortable.
The best solution is the installation of specially designed flat roof windows.
FAKRO flat roof windows illuminate interiors with natural light, providing room ventilation and combining high functionality with perfect thermal insulation parameters. Now every room under the flat roof can be warm and full of natural light.
The EF_ Flat Roof System makes it possible to install windows on flat or very low-pitched roofs. The system elevates the installation angle of the window by 15° in relation to the roof pitch. The system is mainly used in order to provide some more natural light into factories and warehouses while at the same time maintaining good thermo-insulating properties.
The EFR flat roof gable is similar to EFW flat roof, but a much more advanced system. It is an aesthetic and highly effective solution to illuminate the rooms in buildings with low angle roofs.
Flat roof windows are available in three versions:
|DEF - electrically opened||DEC - electrically opened|
|DMF - manually opened||DMC - manually opened|
|DXF - non-opening||DXC - non-opening|
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.
profiles are filled inside with insulating material, thus additionally improving the energy saving parameters of the product.
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.
The electrically operated windows (type F and type C) have a built-in sensor that automatically activates the sash closing function when it rains.
Window type C - The special structure of FAKRO flat roof windows provides excellent thermal insulation parameters. The DEC U8 window with a passive, quadruple U8 glazing unit is characterised by a heat transmittance co-efficient for the whole window of U=0.55 W/m2K (to EN1873). This result is for a 120x120cm window including frame with a sash and a dome.
Window type F -The type F window is available with a quadruple DU8 glazing unit. The heat transmittance co-efficient for the whole window is U=0.76 W/m2K (to EN 12567-2) and makes the window suitable for use in energy-efficient and passive buildings.
In addition to standard sizes, the type F window can be manufactured in any size. The thermal insulation standards of buildings have been significantly increased and old skylights in flat roofs do not meet current requirements. The specification of the type F window allows for the easy and accurate replacement of existing often non-standard size skylights. This provides an improvement of the thermal insulation properties for the whole building.
The flat roof window can be also mounted on an additional XRD base with a height of 15cm, which raises the window and allows its installation in green or living roofs.
The specially designed shapes of the flat roof window profiles gives a glazing area that is up to 16% greater when compared with other manufacturer’s windows of a similar size.
