A super-insulating triple glazing

The iWINDOW3 Fixed Flat Roof Window offers you excellent insulation thanks to its compact and insulating PVC frame, combined with super-insulating safety glazing. For added safety, the inner glass is a laminated glass, and the outer glazing is tempered for greater resistance.

Available in 3 shades, this window model offers you the possibility of determining the desired light intensity according to your needs: the clear shade for absolute transparency and maximum light input, the opal shade to meet a need for privacy while reducing the sensation of glare in your room, and the anti-heat shade to filter more sunlight and to cope with greater heat.

A curb designed for maximum brightness

Compatible with all types of roofing membranes, the iWINDOW3 Fixed Flat Roof Window is equipped with a 20/00 EP Curb in insulating PVC, stabilized by a specific anti-UV treatment resistant to discoloration. Furthermore, its polymer composition combines lightness and strength, greatly facilitating its handling and installation.

With its straight shape, the 20/00 EP Curb has the advantage of offering maximum brightness. Indeed, unlike an inclined curb, 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.

Thus, for the same dimensions, you benefit from maximum light input, all at the same price!

Equipped with a Raw Anodized Aluminium Flashing, the latter ensures good water drainage to avoid any stagnation on the roof. For large-dimension windows, the flashing is assembled and fixed using stainless steel self-tapping screws with a Nyplas collar, thus facilitating its handling. It is also fitted with four ASA synthetic corner pieces reinforcing the whole assembly.

Pre-assembled Electric Blinds

To fully enjoy natural light without raising the temperature in your room, the Electric Blind is an ideal ally. Equipped with a 230 V mains power supply, this electric blind 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 designated location of your flat roof window needs to be planned.

The Electric Blind is available in 3 versions: the Open-weave Version to create a shaded area while maintaining a clear view of the outside, the Sun-shading Version to filter UV rays while enjoying a dimmed light, and the Blackout Version to block all sources of light from entering while keeping you out of sight.

Manual Blinds

The Manual Sun-shading and Blackout Blinds stand out for their ease of use. Made from an off-white fabric, they have a light transmission of 20% and 0.5% respectively, allowing you to partially or completely protect yourself from UV rays while reflecting heat.

When unfolded, the blind perfectly conceals the taut cables and their drop point, letting no light through that could show on the floor of your room. Its opening system operates via a removable pole 1.5m in length.

Our manual blind models are available on simple request via our Online Quote Form.

The External Sun Shade

Composed of a lacquered aluminium frame in Dark Grey (RAL 7021), the External Sun Shade is installed directly onto the frame of your flat roof window from your rooftop. Thanks to its clip-fixing system, installation is simple and fast. The advantage lies in the fact that it offers solar protection up to 8 times greater than an interior sun shade.

Held in place by a rubber profile, the blind is made of a 50mm thick fibreglass fabric with a PVC coating for optimal weather resistance. In addition, these characteristics limit the contact noise encountered in the event of rain or hail. It can be installed at temperatures between -20 and 70°. With its 6% light transmission, this sun-shading blind stands as a high-performance heat shield.
