What is Aerogel?

Aerogel resists the transfer of heat, making it a great insulator.

Studies show that comfort, productivity, learning, healing and customer consumption/retention are dramatically improved by the tactical use of natural light as the primary source of illumination in workplaces, schools, hospitals, homes, and retail environments. Traditionally, this had resulted in a compromise, as the conventional materials used to transmit natural light have demonstrated an inability to insulate, while highly insulative materials have been unable to transmit meaningful quantities of daylight.  Current transparent daylight systems, while allowing maximum daylight, also bring problems such as glare, solar overheating, drafts, hot spots, and high contrast zones.  Harnessing the exclusive properties of Lumira® aerogel for use in daylighting systems has changed all that with:



– Unsurpassed thermal insulation
– R-value of 8 per inch / U-value of .64W/m²K per 25 mm’
– Increased natural light transmission
– 75% per 3/8 inch / 80% per cm
– Superior light diffusion – elimination of glare
– Improved acoustic performance
– Reduced solar heat gain/loss
– Decreased energy consumption – heat, air conditioning, lighting, ventilation, carbon emissions
– Unmatched moisture resistance – 100% hydrophobic
– Exceptional color stability and insulation performance

Aerogel is among the lightest and most effective insulating materials in the world.  Cabot’s Lumira® brand aerogel, formerly Nanogel®, is a solid which consists largely of air (>90%) contained in a structure with pore sizes less than the mean free path of air molecules, which severely inhibits heat transfer through the material, enabling world-class performance.  Cabot produces Lumira® aerogel at its state of the art manufacturing facility located near Frankfurt, Germany where it began commercial production in 2003.
