★ CHAPTER 1 · THE DARKNESS

Deep inside a home beneath a flat roof

Somewhere beneath a flat roof, where the sun never seems to reach, our story begins. An old, dull skylight keeps the daylight out. Cold in winter. Stifling heat in summer. And then there is that annoying tapping with every rain shower.


Pff. It NEVER really gets bright in here.

★ AND AS IF THAT WASN'T ENOUGH

The summer heat strikes

In summer, it gets stiflingly hot under old glazing. The room becomes unbearable. Someone has to do something about this. Someone with flat glass, top insulation and solar-control superpowers.

SWELTER!

Openable iWindow flat roof window with electric screen on solar power

★ CHAPTER 3 · THE SOLAR SUPERPOWER

Powered by the sun. Without a single cable. ZZON!

Meet the Solar iWindow. A compact solar panel on the outside charges a hidden battery. That battery opens your flat roof window, extends your screen and keeps everything running autonomously for months. No channels in the ceiling, no cable ducts, no power socket. Ideal for renovations, outbuildings and hard-to-reach places.

★ 2 HOURS OF SUN

Works even in winter

The high output of the solar panel makes the system remarkably tolerant. Around 2 hours of direct sunlight per day is enough, even during short winter days. Made for the Belgian sky.

★ 4 WEEKS OF AUTONOMY

Grey week? No panic.

A fully charged battery bridges up to 4 weeks without direct sunlight. You can monitor the battery status via the app or the LED indicator. And if really needed, you can recharge it from the inside via USB C.

★ THREE TYPES OF SCREENS

Solar shading, blackout or insect screen

Choose from three fabrics when purchasing. Solar shading against heat, blackout for a pitch-dark room or insect protection for fresh air without unwanted guests. All wirelessly operated.

iWindow flat roof windows wirelessly compatible with smart home via Matter

★ CHAPTER 4 · SMART HOME, EASY LIVING

Matter, the language of every smart home CLICK!

What is Matter? Imagine this: every brand in your home used to speak its own little language. Apple spoke Apple, Google spoke Google and the rest barely understood each other. Matter is the universal language that puts an end to that. Every device that speaks Matter understands every other Matter device. Simple.

Your iWindow speaks Matter fluently. In practice, this means you can open your flat roof window with your voice via Siri, Google Assistant or Alexa. One tap on your smartphone is enough, or let the window open automatically when it gets too warm inside. The DuoControl remote control comes standard in the box.

«Siri, open the roof window.» Done. Your home listens.
