What makes this product green?

  • Reduces heating and cooling loads
  • Improves light quality


Cabot’s synthetic silica aerogel, Lumira, provides both high insulating value (R-8/inch) and high light transmissivity (53% with 1” thickness). The product is UV-stable, hydrophobic, and non-combustible. The lightweight microporous structure reduces sound transmission as well as heat conductionMovement of heat through a material as kinetic energy is transferred from molecule to molecule; the handle of an iron skillet on the stove gets hot due to heat conduction. R-value is a measure of resistance to conductive heat flow. and convection. This aerogel provides diffuse daylightingUse of sunlight for daytime lighting needs. Daylighting strategies include solar orientation of windows as well as the use of skylights, clerestory windows, solar tubes, reflective surfaces, and interior glazing to allow light to move through a structure. without sacrificing energy performance, and has been used for a number of daylighting products.
