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.
Enrich your home with the
Sleek design of the iWindow flat roof window
The iWindow flat roof window distinguishes itself with its contemporary and sleek design. The compact PVC frame and the aesthetic framing contribute to its modern appearance. This sleek design is a valuable addition to any modern home, giving your interior a stylish upgrade.
Experience the benefits of a
Flat roof window with a high insulation value
A Skylux flat roof window not only offers an aesthetic aspect, but also an impressive insulation value. With a U-value of up to 0.5 W/m²K for the H+++ glass and a sound reduction of 41 dB, you can enjoy excellent thermal and sound insulation. Furthermore, we offer a guarantee on an EPB-compliant solution, ensuring you an energy-efficient and environmentally friendly choice.
Enjoy up to 40% more daylight
Plenty of natural daylight
Our flat roof windows are always delivered with a straight curb, which means that the daylight surface entering through a 100x100 cm window is actually 1 m². Unlike competitors who use splayed curbs that provide a smaller daylight surface as the dimensions of the roof opening are larger than the actual daylight size. This means that you have to purchase a larger skylight from our competitors to get the same 1m² of natural daylight. Choose our flat roof windows and benefit from a maximum amount of natural light in your home.
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 design and convenient hinge system, you can easily attach the glass frame (iWindow2, iWindow3, or iDome) to a chosen curb. Fast, easy, and cost-effective!
