Fixed iWindow3 flat roof windows

With the Skylux iWindow3 flat roof window, you choose the best possible insulation and a modern, sleek look. This flat skylight is super-insulating (Ug value of 0.5 W/m2K) thanks to the compact, insulating PVC frame and the triple-walled super-insulating HR+++ safety glass. You save up to 81% energy compared to a classic double-walled plastic skylight.
