Choice of glass: clear, opal or solar control
Transparent clear glass
Clear or transparent glass is the traditional choice for many homeowners and businesses because of its classic beauty and clarity. It allows us to experience daylight in its purest form, contributing to a spacious and inviting atmosphere. At the same time, it provides a lovely outside view without disturbing elements.
Opal glass
Opal glass offers the ideal balance between natural light and privacy. The milky white colour provides an even distribution of light, while limiting visibility from the outside. A popular choice for bathrooms and other spaces where privacy is important. Opal glass also helps reduce harsh shadows and glare from direct sunlight.
Solar control glass
Designed to keep out the heat of the sun without sacrificing any daylight. This type of glass reflects the sun's rays and reduces heat transmission, keeping the interior cooler during hot summer days. There is no change in colour perception of the glass or perception of the interior space under the window.

In addition, we guarantee an EPB-compliant solution, ensuring you of an energy-efficient and environmentally friendly choice. Experience the comfort and efficiency of a flat roof window with unmatched insulation performance.
Enjoy up to 40% more daylight
Plenty of natural daylight
Our flat roof windows are always supplied with a straight curb, which means that the light area entering with a skylight of 100x100 cm is also truly 1 m². In contrast to competitors who use sloped curbs, this results in a smaller light area, since the dimensions of the roof opening are larger than the actual daylight size. Concretely, this means that with the competitor you have to buy a larger skylight to get the same 1m² of daylight. Choose our flat roof windows and benefit from a maximum amount of natural light in your space.
Upgrade your skylight
Replace your old skylight without changing the curb!
This solution is perfect if you only want to replace your old skylight without changing the existing curb. With our fixed version and the convenient hinge system, you can easily install the glass window (iWindow2, iWindow3 or iDome) on a curb of your choice. Fast, easy and cost-effective!
