Sun protection

Daylight incidence and solar heat input create a broad potential to direct energy into buildings and thus save costs for heating and artificial lighting. Of course, this must not happen in an uncontrolled way, but must be adjustable by controllable shading systems. The external shading system for our LAMILUX Flat Roof Access Hatch Comfort Swing is suitable for this. With noise-optimised retractable sliders, the external awning can be easily extended using push buttons or a radio remote control, thus allowing optimum control of the amount of daylight entering the room. The cable routing is concealed and integrated in the top element.

Opening Drives

An infinitely variable opening takes place over the leaf by one hydraulic cylinder per narrow side, which is operated by an electrically operated hydraulic unit (230 V). The Flat Roof Access Hatch Comfort has a limit switch as opening monitoring on the opposite narrow side of the exit as well as a light barrier for monitoring the exit area of the element. To open the element, the hydraulic unit is controlled via a key switch with dead man's switch.

Top Element

The top element (top roof edge dimensions 100 cm x 300 cm or 100 cm x 350 cm) forms the base for the construction. It provides the ideal thermal connection to the building structure. The extension element consists of a steel construction and is insulated throughout with mineral wool. The inside is covered with a coated aluminium sheet in all RAL Classic colours 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 height of the top element is 41 cm on the eaves side and 50 cm on the opposite long side.  The inclination of the surface is 5°, which supports an ideal self-cleaning of the element.

Energy Efficiency

Our LAMILUX Flat Roof Access Hatch Comfort Swing has optimal isothermal curves and thus a minimized condensation risk. The flat roof access hatch also has high thermal insulation in the joint area.
