One of the most significant advances in daylighting in more than 20 years, Structural Composite panels are lightweight and high strength, making them the perfect match for Lumira® insulation. Commercial and residential systems insulated with Lumira aerogel are cost-effective, providing 3x the thermal performance and the following additional benefits:


  • Significant sound attenuation
  • Permanent thermal performance 
  • Up to R20 insulation (0.28 Wm2/K) with 20% light transmission


The following comparison chart is based on the performance of Kalwall Structural Composite panels with and without Lumira aerogel.
