Thanks to its smart straight upstand design
Skylux iWindow comes standard with a straight upstand, allowing full use of the opening for daylight. 100x100 cm truly means 1 m² of light – no loss from slanted edges or thick frames.
This gives you up to 40% more daylight than traditional skylights with a sloped upstand, bringing in more natural light and instantly improving your living comfort.
