Lumira ® Aerogel

Polycarbonate Fill Solutions

What is Lumira®?

Lumira aerogel, formerly Nanogel aerogel, is an insulating gel used to fill polycarbonate for many architectural systems and applications. Lumira aerogel’s main purpose is to increase thermal ratings, but it can also greatly reduce sound transmission difference.

Lumira aerogel consists of small clear hydrophobic particles, creating an R-Value of 6.5 for a 25mm, 3 wall unit, compared to an R-Value of 3 for an unfilled unit. After Lumira aerogel is added to the polycarbonate, the thermal transfer of heat and cold is greatly reduced, minimizing energy costs on installations.

In certain applications, Lumira aerogel can aide in LEED certifications. Sustainable purchasing, optimum energy efficiency, occupant comfort, and low emissions, along with daylight and views, are possible points Lumira can assist with.


   

What is Lumira® Aerogel Made Of?

The actual Lumira aerogel product is translucent and made from a dry silica particulate with the ability to retain a large amount of light transmittance.Values range from 70% light transmittance for a 10mm sheet of polycarbonate to 50% with 25mm of polycarbonate when filled. Another benefit of incorporating Lumira aerogel is glare reduction.Lumira aerogel infill can be used to diffuse light if harsh glare is a problem. Energy savings will likely occur when sunlight and heat gain are reduced in a space. Lumira particles do not harbor mold, moisture, mildew, or fungus. They are completely safe to be around, and they do not emit any odors. The aerogel particles are UV-stable and will not deteriorate due to sunlight exposure. If a skylight is filled with Lumira aerogel and requires  replacement, the  Lumira aerogel particles can be reused and recycled under certain conditions in the replacement skylight.

Thermal Benefits:

Aerogel is among the lightest and most effective insulating materials in the world. Lumira aerogel is a solid consisting largely of air (>90%) contained in a structure with pore sizes that are smaller than the space required for air molecules to travel through. This severely inhibits heat transfer through the material, enabling world-class performance.

Lumira Aerogel Polycarbonate Curtain Wall ApplicationLumira filled polycarbonate is more than three times more effective at insulating than non-lumira filled polycarbonate. With 25mm Lumira filled polycarbonate having an R-Value of 9.09 vs standard 25mm polycarbonates R value of 2.94, the amount of energy conducted is drastically cut, saving you money and increasing your comfort. Not only is the thermal performance based on conduction greatly increased, the ability to control solar heat gain and still having a high amount of visible light is an added benefit. Lumira filled polycarbonate decrease the solar heat gain from 71% to 61% on clear 25mm polycarbonate decreasing necessary cooling loads.Lumira Aerogel Window Application

Acoustical Benefits:

Lumira aerogel can be used to achieve specific levels when acoustical ratings are required. The beads block and absorb sound. The result is strong sound control by reducing outside noise transfer. Interior spaces and rooms become quieter and user comfort levels increase with the assistance of Lumira aerogel.

The key feature of Lumira aerogel in a sound control application is the low speed of sound waves (airborne) propagating through the porous medium, as well as, poor solid vibration transmission. This is due to Lumira aerogel’s tenuous structure. For additional technical details, please contact a sales representative at 800-618-0669 or skylight@solarinnovations.com..

Lower sound velocity in Lumira aerogel makes the material particularly adapted to low frequency sound control where space is a concern.

The noise reduction coefficient is the average of the absorption at four frequencies (250, 500, 1000, and 2000 Hz). The NFRC, however, does not reflect material performance at specific frequencies of interest for the application. The sound absorption properties of Lumira granules can be modified to match the needs of a particular application by changing both the mechanical properties of the material as well as the particle size distribution.

Translucent Panels – Light Transmission Benefits:

The inclusion of Lumira in daylighting systems virtually eliminates the historical trade-off of insulation vs. natural light by providing 3 to 6 times the thermal performance of traditional, insulated fenestration products, while maintaining optimal light transmission. Solid, non light-trans-missive construction delivers an R-value of 24 (U-value 0.04), which allows daylighting products to deliver a range of R-values from 6 to 20 (U-0.05 to 0.16), while cultivating essential natural daylight. Increased daylighting designs are proven to have positive effects, such as:

 

  • Increased productivity
  • Increased sales
  • Increased learning rates
  • Decreased absenteeism
  • Promotes a healthier, happier work and educational environment

Inclusion in Any Daylighting Product:

There are many applications for Lumira aerogel, such as curtain walls, interior walls, skylights, sloped sunrooms, pool enclosures, greenhouses, conservatories, walkways, and canopies. These applications all have the potential to benefit from Lumira aerogel fill. Lumira aerogel can also be placed inside bent and radius units.

Commercial hotels, restaurants, multi-family housing, schools, and health care buildings have the ability to incorporate Lumira aerogel into their new glazing construction.  Residential Lumira aerogel applications include skylights, glazed structures used for entertaining or plants, or an outside canopy.
