Frequently Asked Questions

 

Are Cabot's aerogel product safe?

Yes. Cabot's aerogel products, including Lumira® aerogel and Enova™ aerogel, are surface-treated precipitated synthetic amorphous silica gel that is chemically very similar to other silica products. It consists of 97% treated precipitated silica amorphous silica gel and 3% water. Precipitated silica is a common product used in personal care products such as lotions and cosmetics. Cabot's aerogel products do not contain crystalline silica and are neither carcinogenic nor mutagenic.

Are Lumira® daylighting systems resistant to moisture?

Lumira® aerogel is completely hydrophobic in nature. It is this feature that prevents any type of mold or mildew growth within the system.

Are the daylighting systems with Lumira® insulation considered a "Green Product"?

Lumira® aerogel is safe, non-hazardous and environmentally friendly. Additionally, the McDonough Building Design Council (MBDC) contends Cabot's aerogel is consistent with the MBDC "Cradle to Cradle" Design Philosophy.

How does aerogel differ from existing fumed silica products?

Aerogel is a treated silica product with a surface that looks chemically similar to common silica products. The most significant difference is the higher surface area or larger pore volume of the aerogel compared to the silica.

How is Cabot's aerogel manufactured?

Cabot Corporation’s aerogel manufacturing process is analagous to the commercial production of silica gel. The treated gel is dried preserving its porous structure and rendering the product hydrophobic through a patented process.

Is Lumira® aerogel a proven insulation material in the the architectural market?

Yes, Lumira® aerogel, formerly Nanogel® aerogel, has been successfully installed in a variety of daylighting systems in both North America and Europe. Installations have ranged from schools, to hospitals, to swimming pool and office enclosures.

Is Lumira® aerogel insulation UV stable (will there be any discoloration over time)?

Lumira® insulation systems are UV stable. Neither the properties (color stability) nor performance (insulation) of translucent Lumira™ aerogel will degrade over time.

How is Cabot's aerogel manufactured?

Cabot Corporation’s aerogel manufacturing process is analagous to the commercial production of silica gel. The treated gel is dried preserving its porous structure and rendering the product hydrophobic through a patented process.

What are the key attributes of daylighting systems with Lumira® insulation?

Improves thermal performance, Increases light transmission, Improves ability to meet building codes without tradeoffs; Improves condensation resistance factor, Improves acoustic performance.

What is Cabot aerogel?

Lumira® aerogel and Enova aerogel are Cabot Corporation’s trade names for its family of hydrophobic silica aerogel.

What is the appearance of the Lumira® insulation system inside a channel glass cavity?

The natural vertical channels of the polycarbonate create a vertical appearance when translucent Lumira® aerogel is filled inside the polycarbonate panel, consistent with the linear appearance of channel glass. Lumira® aerogel provides an “ice cube” appearance inside the channel glass. To mute the distinctiveness of the vertical channels of the Lumira® aerogel-filled polycarbonate panel, an opaque-colored panel is also available.

How are the multiwall polycarbonate panels filled with Lumira®?

Multiwall polycarbonate panels are filled with Lumira® aerogel on a purpose-built patented machine. The panels are secured in the filling machine and Lumira® aerogel is poured into the "flutes" of the panels. A vibrating bar ensures the particles settle tightly and uniformly into the flutes of the panel. This process is done in a controlled environment (proper humidity and temperature) to prevent static clinging. The machine is capable of filling up to 6' wide polycarbonate panels.

Will the Lumira® "settle" after the panels are filled?

After each multiwall polycarbonate panel is filled, it is tamped and left to sit for 24 hours. Once the 24 hour "settle" period has past, the panels are tamped again, inspected with high intensity lights, and filled with additional Lumira® as required.

What keeps the Lumira® in the polycarbonate panel?

The multiwall polycarbonate panels are sealed at the "open" top and bottom ends with a special AntiDust venting tape. The tape secures the Lumira® aerogel in the panel while allowing the panels to breath.

 

"Lumira® is safe for human (particle sizes from 1 to 4mm) and ecological systems, and is manufactured with little or no impact on the environment. This means including daylighting systems with Lumira® insulation in building designs can help create healthier living, recreational, and work spaces."
