A flat glass skylight with a sleek and modern design. The Skylux iWindow2 excells in insulation (Ug-value of 1.0 W/m²K) thanks to the compact, insulation PVC frame and the super insulating safety glass HR++. You save up to 63% of energy compared to a classic double-walled plastic skylight. It also provides plenty of daylight.

 

Features:

  • sleek look

  • double glazing, safety glass HR++

  • high insulation value: Ug = 1.0 W/m²K

  • light incidence surface = daylight size

  • aesthetic 28 mm frame

  • good sound insulation 39 dB

  • suitable for flat roofs with a pitch between 5° and 25° to avoid dirt and water stagnation

Our flat skylights are also available as openable versions! You can get the Skylux iWindow2 in combination with our 20/00 EP curb (upstand) as a complete set in an openable version. Perfect for fresh air ventilation.

Thanks to the built-in actuator in the upstand, you can close and open the glass skylight with the supplied remote control. The electric interior sunblind keeps the heat outside.
