A super-insulating triple glazing

The iWINDOW3 Opening Flat Roof Window offers 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 toughened for greater resistance.

Available in 3 tints, this window model gives you the ability 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 sensation of glare in your room, and the heat-protection tint to filter more of the sun's rays and overcome greater heat.

A kerb designed for maximum brightness

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

Photo of the 20/00 EP Kerb for the iWINDOW3 Opening Flat Roof Window

With its straight shape, the 20/00 EP Kerb has the advantage of offering maximum brightness. Indeed, unlike an angled kerb, the incoming light surface area — for example, for a roof window measuring 100 x 100cm — suffers no loss, with an actual value of 1 m².

This way, for the same dimensions, you benefit from maximum light input — at the same price!

Equipped with an anodised Raw Aluminium Flashing, it ensures proper water drainage to prevent any stagnation on the roof. For large-sized windows, the flashing is assembled and fixed using stainless steel self-tapping screws with a Nyplas collar, making it easier to handle. It also features four ASA synthetic corner pieces that reinforce the whole assembly.

Adjust the ventilation with a simple gesture

The PVC Costière 20/00 EP is equipped with an integrated 24V motor with a single or double actuator depending on the weight of your iWINDOW model. The motorisation is provided by an integrated control unit and a remote control automatically connected to the complete set.

The control unit features open contacts in anticipation of adding a home automation system, or should you wish to connect fixed push buttons.

Its propulsive force reaches 1500 N at a speed of 7mm/s, giving the iWINDOW Roof Window an opening and closing time of just 15 seconds.

Pre-mounted Electric Blinds

To fully enjoy natural light without raising the temperature in your room, the Electrically Operated Blind is an ideal ally. Equipped with a 230 V mains power supply, this electric blind can be controlled using the remote control of your iWINDOW Flat Roof Window, or from your Smartphone. 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 all you need is a 230V mains power supply at the planned location of your flat roof window.

The Electrically Operated Blind comes in 3 versions: the Insect Screen Version to create a shaded area while maintaining a clear view of the outside, the Sun Shade Version to filter UV rays while enjoying soft light, and the Blackout Version to block all light sources from entering while keeping you protected from prying eyes.

Manual Blinds

The Manual Sun Shade 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, providing partial or complete protection 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

Made from a lacquered aluminium frame in Dark Grey (RAL 7021), the External Sun Shade installs directly onto the frame of your flat roof window from your rooftop. Thanks to its clip-fixing system, installation is simple and quick. The key advantage is that it offers up to 8x greater solar protection compared to an interior sun shade.

Held in place by a rubber profile, the blind is made of fibreglass with a thickness of 50mm and a PVC coating for optimal weather resistance. In addition, 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 acts as a highly effective heat shield.

Pre-mounted LED Lighting

The day is drawing to a close but you want to maintain maximum brightness in your room? The LED Lighting option is the ideal solution to ensure optimal visibility day and night.

An LED strip 2cm wide is integrated and pre-mounted directly onto your kerb. The whole unit can be controlled with an included remote control.

The Rain Sensor

Designed for opening models, this externally mounted sensor automatically triggers the closing of your flat roof window in the event of rain. This way, you can leave your iWINDOW window open with complete peace of mind, without worrying about your room getting wet.
