Sun Protection

Daylight and solar heat have the potential to increase light and heat energy inside buildings which can be used to save costs for heating and artificial lighting. This needs to be controlled by adjustable shading systems. The external shading system for LAMILUX Flat Roof Exit Comfort Swing is suitable for this. With noise-optimized retractable sliders, the external awning can be easily extended using push buttons or a radio remote control allowing optimum control of the amount of natural light entering the room. The cable routing is concealed and integrated in the top element.

Opening Drives

Opening takes place over the leaf using a hydraulic cylinder on each narrow side, this is controlled by an electrically operated hydraulic unit (230 V). The Flat Roof Exit Comfort has a limit switch which monitors the opening on the opposite narrow side of the exit and a light barrier for monitoring the exit area of the element. To open the roof hatch, the hydraulic unit is controlled via a key switch with a dead man's switch.

Top Element

The top element forms the base for the construction and creates an ideal thermal connection to the building structure. The extension element is made of steel insulated throughout with mineral wool. The inside is covered with a coated aluminum sheet in any RAL Classic color and the outside with white pigmented GRP. The top element complies with DIN 18234 - prevention of fire expansion on the roof without additional measures.

The top element has a 5° inclination, which supports an ideal self-cleaning of the element.
