The LAMILUX Flat Roof Access Hatch Comfort Square offers the best fit for the roof terrace and creates architectural freedom. The square shape means that spiral or platform staircases can be used, which is particularly suitable for purist design requirements. Thanks to a filigree frame construction with a light area of 4 m², the flat roof exit comfort square offers maximum daylight incidence. The concealed hydraulic drives ensure a clean design. The element only needs around 45 seconds to reach its maximum opening angle of 70 degrees. This offers a high level of comfort, saves space on the roof terrace and ensures sufficient fresh air inside the building. The five-degree inclined curb supports water drainage from the pane.
