A super-insulating double glazing
The Fixed Flat Roof Window iWINDOW2 offers you excellent insulation thanks to its compact and insulating PVC frame, combined with the super-insulating safety glazing. For added safety, the inner glass is laminated glass, and the outer glazing is tempered for greater resistance.
Available in 3 tints, this window model gives you the possibility to determine the desired light intensity according to your needs: the clear tint for absolute transparency and maximum light input, the opal tint to meet a need for privacy while reducing the feeling of glare in your room, and the anti-heat tint to further filter sunlight and to cope with greater heat.

An upstand designed for maximum brightness
Compatible with all types of roofing membranes, the Fixed Flat Roof Window iWINDOW2 is equipped with a 20/00 EP Upstand in insulating PVC, stabilised by a specific anti-UV treatment resistant to discolouration. Furthermore, its polymer composition combines lightness and strength, which greatly facilitates handling and installation.

With its straight shape, the 20/00 EP Upstand has the advantage of offering maximum brightness. Indeed, unlike an angled upstand, the incoming light surface area, for example, for a roof window measuring 100 x 100cm, suffers no loss, with a real value of 1 m².
This way, for equal dimensions, you benefit from maximum light input, all at the same price!
Equipped with a Raw Anodised Aluminium Flashing, it ensures proper water drainage to prevent any pooling on the roof. For large-dimension windows, the flashing is assembled and secured using stainless steel self-tapping screws with a Nyplas collar, making handling easier. It also features four ASA synthetic corner pieces to reinforce the whole assembly.

Pre-assembled Electric Fabrics
To fully enjoy natural light without raising the temperature in your room, the Electrically Operated Fabric is an ideal solution. Equipped with a 230V mains power supply, this electric fabric is controllable via its 4-button Niko switch. There is no need to wire this device as it features a wireless Bluetooth module. Installation is done in the blink of an eye, and only a 230V mains power supply at the intended location of your roof window needs to be planned.
The Electrically Operated Fabric comes in 3 versions: the Open-Weave Version to create a shaded area while maintaining a clear view of the outside, the Sun Blind Version to filter UV rays while enjoying diffused light, and the Blackout Version to prevent any light source from entering while keeping you out of sight.

Electric Open-Weave Fabric
Electric Sun Blind Fabric
Electric Blackout FabricManual Fabrics
The Manual Sun Blind and Blackout Fabrics stand out for their ease of use. Made from an off-white fabric, they have a light transmission of 20% and 0.5% respectively, providing partial or complete protection from UV rays while offering heat reflection.
In the unfolded position, the fabric perfectly conceals the tensioned cables and their anchor points, letting no light through that could show on the floor of your room. Its opening system operates via a removable pole with a length of 1.50m.
Our manual fabric models are available on request via our Online Quote Form.

The Exterior Sun Blind
Composed of an aluminium frame lacquered in Grey Black (RAL 7021), the Exterior Sun Blind is installed directly onto the frame of your flat roof window from your rooftop. Thanks to its clip-on fixing system, installation is quick and easy. The advantage lies in the fact that it offers solar protection up to 8 times greater than an interior sun blind.
Held in place by a rubber profile, the fabric consists of a fiberglass layer 50mm thick with a PVC coating for optimal weather resistance. Furthermore, these characteristics limit contact noise encountered in the event of rain or hail. It can be installed at temperatures ranging from -20 to 70°. With its 6% light transmission, this sun blind stands as a high-performance anti-heat shield.
