LAMILUX Continuous Rooflight: The advantages

With the LAMILUX CI System Continuous Rooflight S, we have developed a state-of-the-art continuous daylight system in a gable roof design for flat roofs in industrial and administrative buildings. Our objective as one of the most experienced manufacturers: extremely stable and aesthetically-pleasing design for energy-efficient and sustainable construction of the future!


  • The world's first continuous rooflight with audited watertightness under heavy rain and storm (DRI 3.0 m/s²)
  • The use of new materials ensures a completely thermally-separated structure in order to satisfy the highest energy-efficiency standards in modern industrial and administrative buildings
  • Thanks to innovative system components, such as the bionically dynamic tensioning technology (BDT), the continuous rooflight structure is able to withstand the heaviest wind and snow loads
  • Wide range of glazing

Energy efficiency

  • Thermally separated mullion-and-transom structure and flap systems
  • Isothermal Load Converter (ITL) – a component for using materials with excellent heat insulation properties at theanchor point
  • Composite glazing adapted to the project-specific energy requirements (sheet thickness 10 to 32 millimetres) with low thermal transmittance coefficients of up to 1.2 W/(m²K)
  • High energy-saving daylight intake and controllable solar heat input
  • Energy-efficient natural ventilation
  • LCA made easy: For our CI System Continuous Rooflight S there is an comprehensive product declaration according to ISO 14025 and EN 15804 (EPD - modules A1 - D)


  • Bionically dynamic tensioning technology (BDT) in the ridge area for flexible force/tension compensation in the case of heavy wind and snow loads
  • Active expansion absorber (AEA) for absorbing expansion differences between sealings and tensioning bars in the glazing bars
  • Dynamic torque control (DTC) for perfectly-tensioned and secure mounting of the glazing in the flap systems
  • Flap systems that can be combined in various size variations for perfectly-dimensioned smoke extraction surfaces
  • Linear burn-through protection (LBP) to prevent the spread of fire on the roof
  • Integration of smoke and heat exhaust systems (SHEVS) and SHEVS control panels


  • Architecturally appealing structure in gable roof design
  • Modern overall impression of forward-looking construction
