Design and Comfort

  • Generous daylight incidence
  • Convenient access to the roof terrace via stairs (on-site)
  • Self-cleaning due to 5° inclined upstand
  • Partial glazing on a 3° sloping upstand on the eaves side
  • Infinitely variable ventilation position of both leaves
  • Clear optics: no interfering edges and no visible drive units in the interior
  • Variety of colors according to RAL card (edging profiles)
  • Leaf system, motor opener and upstand are completely pre-assembled at the factory

Energy Efficiency

  • Complete construction without thermal bridges
  • Completely thermally insulated upstand
  • Can be equipped with the highest quality functional glass
  • Minimized risk of condensation

Energy Efficiency
Isothermal lines indicate points featuring the same temperature and reveal a measurable customer benefit in a thermal diagram. E.g. The 10° isothermal line is a measured variable used to ensure protection against condensate. If this line wanders outside the confines of a structure, condensate or even hoar frost will form precisely at this point.

Safety

  • Closing and opening from outside possible via optional key switch (min. IP54)
  • Emergency stop function during closing by light barrier
  • As a standard: Outer pane TSG, inner pane LSG

Upstand - Stability and Thermal Insulation

The base of the system is a seamlessly manufactured upstand that provides an ideal thermal connection to the building structure. LAMILUX upstands made of glass-fiber reinforced plastic are CFC-free, completely pigmented white and thermally insulated with rigid polyurethane foam. They have a weatherproof seal and are not considered to be burning drips and comply with DIN 18234 without additional measures. To make them very stable and torsion-resistant, LAMILUX upstands have a closed box cross-section.

The continuous insulation, at least 55 mm thick, ensures an excellent heat transfer coefficient of 0.6 W/m²K. The upstand is 35 cm high on the eaves side and rises by 6° to 68 cm on the ridge side. This supports the self-cleaning of the element.
