Self-supporting U-shaped cast glass system providing structural glazing with excellent daylighting, spans up to 7m vertical, thermal performance U-value 0.49-2.5 W/m²K depending on configuration

Overview
Executive summary

Profilated glass (U-channel) is a continuously cast glass product with a distinctive U-shaped cross-section, originally developed in Austria and refined in Germany over 35+ years. The three-dimensional profile creates a self-supporting structural glass system capable of spanning up to 7 metres vertically without intermediate supports. Available in 6mm and 7mm thicknesses with various widths (232-498mm) and surface textures, it provides diffused natural daylighting while maintaining privacy. The system can be installed single or double-glazed, achieving U-values from 2.5 W/m²K (single) to 0.49 W/m²K (double with insulation).

Best when…
  • Self-supporting structure reduces framing requirements
  • Excellent daylight diffusion without glare
  • Long spans possible (up to 7m vertical)
  • Good thermal performance in double-glazed configuration
  • No vertical mullions required for continuous facades
  • Can achieve curved installations
  • Provides privacy while transmitting light
  • Non-combustible material suitable for fire-rated assemblies
  • 100% recyclable at end of life
  • Low maintenance requirements
