LAMILUX Flat roof window: The technical details

Design details

Leading technology:

  • The first building approved flat roof window in ‘structural glazing’ design – certified by the German Institute for Structural Engineering (Deutsche Institut für Bautechnik, DIBt) in Berlin
  • Integration of triple thermal insulation glazing with excellent Ug values
  • Outstanding, certified air-tightness due to the new double balloon-type seal
  • A fully heat-insulated upstand made of GRP; seamless and therefore 100% vapour-tight
  • Very high load-bearing capacity due to optimised profiles
  • UV-resistant edge bond
  • Smooth transitions between the glazing and frame profiles ensure unobstructed rainwater run-off with no dirt traps.
  • Surrounding frame with absolutely no thermal bridges, classified as watertight in driving rain, in accordance with EN 12208 E1500 (equivalent to exposure to heavy rain and wind force 14)
  • Optionally available with a 40 cm high upstand with pitch roof geometry for better self cleaning
  • Complies with DIN 18234 with no additional measures required

Energy efficiency

The CI System Glass Element F100 offers complete and optimal heat insulation in a single compact unit that is free of thermal bridges. The Uw value of 1.3 - 1.0 W/m²K is calculated according to EN ISO 10077-1 for a reference element measuring 120 x 120 cm and is dependent on the type of glazing selected.

Isothermal characteristics – Thermal protection made visible

Optimised thermal characteristics for consistent heat insulation zones without any weak spots provide superior heat protection in all sections throughout the structure: evidence of optimum energy efficiency. LAMILUX calls this thermal bridge-free product concept
