  • Structure completely free of thermal bridges with a Uw-value between 1.1 and 0.76 W/m²K, depending on the glazing (as per EN ISO 10077-1)
  • Thermally insulated, jointless GRP upstand, with a height of 70, 50 or 30cm with U-values ≥ 0.68 W/m²K
  • Outstanding air-tightness due to the new balloon double sealing system: Performance class 4 – tested in accordance with EN 12207
  • Life cycle assessment made easy: There is a comprehensive Environmental Product Declaration for the LAMILUX Glass Skylight F100 Circular in accordance with DIN EN 15804, DIN EN ISO 14040, DIN EN ISO 14044 and DIN EN ISO 14025 

Comfort & Design

  • NEW: Chain drives which are invisibly integrated into the upstand, available – Awarded the German Design Award 2020 in the category Winner
  • NEW: 5° inclined upstands available for an ideal self-cleaning effect 
  • Flat drainage surface: The newly designed frame profile provides a smooth transition between the glazing and the border frame, creating an unobstructed drain for rainwater 
  • Permanently clear view and generous daylight through scratch-resistant glazing
  • Our Glass Skylight F100 Circular is BIM-ready – Download at
  • Generous daylight incidence and lasting clear views due to scratchproof glazing
  • White, silk-matt appearance inside – no additional drywall construction required


  • Tested watertightness, even in high wind speeds (driving rain impermeability, in accordance with EN 12208, Class E 1950)
  • Very high load-bearing capacity due to optimised profiles
  • Approved fall-through protection
  • Excellent stability under wind and snow loads
  • UV-resistant edge bond


  • The first building approved glass skylight in “Structural Glazing” design – certified by the German Institute for Structural Engineering (Deutsche Institut für Bautechnik, DIBt) in Berlin
  • Condensation resistant between glass panels due to thermally decoupled edge bond, unlike plastic domes
  • Preventive fire protection: Compliance with DIN 18234 – to prevent fire spread on the roof without additional measures such as gravel fill
  • Can be used as an SHEV system in staircases
  • Delivery of Glass Skylight F100 completely pre-assembled on the upstand

Energy Efficiency

Isotherms – thermal protection made visible

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

TIP – Total Insulated Product

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