Lumira ® Aerogel

Benefits of Lumira® Aerogel

Lumira® aerogel, a translucent product made from a dry silica particulate, is a high performance insulating gel used to insulate a polycarbonate. When added, Lumira® increases thermal ratings and light transmission while reducing glare, sound transmission, and the thermal transfer of heat and cold — the last of which can help minimize energy costs during installation.

Polycarbonate is an effective option when it comes to glazing a structure that will reside in a high traffic or high wind area. The virtually indestructible substance was originally used as a glass replacement, but it is becoming more popular due to its aesthetic qualities and durable composition. However, polycarbonate may need to be insulated in order to achieve maximum user comfort.

In certain applications, Lumira® can assist with meeting LEED requirements, as sustainable purchasing, optimum energy efficiency, occupant comfort, low emission, and daylight points are all possible with Lumira®.

Lumira® can be used is curtain walls, skylights, sunrooms, pool enclosures, greenhouses, conservatories, and practically any other residential or commercial application. Solar Innovations, Inc. has developed a standard line of products featuring Lumira® aerogel for customer convenience, or we can tailor a custom product or structure to include the insulating gel during the design phase.

Societal Impact

  • In the Workplace: Natural light can help increase production and has been proven to raise employee productivity by 2-16%.
  • In the Classroom: Daylighting helps concentration and can increase a student’s performance on tests by as much as 20%.
  • In Healthcare: Patients in hospital rooms with windows or skylights experience shorter stays; as daylight contributes to physical health resulting in earlier patient discharge.
  • In Retail: Studies have shown an average 25-40% increase in sales in retail stores where skylights provide a significant portion of daytime lighting.


Economic Impact

Return on Investment: Performance of Lumira® aerogel yields performance improvements by a factor of four or five. Customers can expect a ROI in under 3-5 years, depending on energy costs.
