How much does aerogel insulation cost?

Even though producing more aerogel at a time would bring its price down, the process and materials alone come with a high price tag of about $1.00 per cubic centimeter. At about $23,000 per pound, aerogel is currently more expensive than gold [source: NASA JPL, FAQs]!

What is spaceloft?

Aspen Aerogels’ Spaceloft® is a flexible aerogel composite blanket designed for insulating buildings and apparel. Great for home insulation, winter clothing, science projects, and any application where thermal insulation is needed and space is at a premium.

What is the R value of aerogel?

R-40/m
Aerogel is an extremely good thermal insulator, which at a pressure of one-tenth of an atmosphere has an R-value of R-40/m, compared to R-3.5/m for a fiberglass blanket.

What is an aerogel blanket?

Aerogel blankets incorporate aerogel particles into ultra-thin, flexible nonwovens with superior insulating properties. ThermalWrap blanket products can provide light transmission, light diffusion and high-performance thermal insulation. They are also: Highly-breathable, but water repellent.

Can you insulate a house with aerogel?

The porous structure of that nanomaterial makes it difficult for heat to pass through. As a result, aerogels make very good and light-weight insulators. But now, a handful of aerogel companies are offering thin blankets that serve as replacements for traditional fiberglass, foam, or cellulose insulation.

How do I make aerogel?

Aerogels are produced by extracting the liquid component of a gel through supercritical drying or freeze-drying. This allows the liquid to be slowly dried off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation.

Why is aerogel so expensive?

Aerogel preparation involves expensive precursors, chemicals, and the need for supercritical drying, making the production relatively more expensive compared to the current conventional building insulations.

What are the disadvantages of aerogel?

Disadvantages: Increased density (typically about one-third to one-half the density of water) Decreased clarity (from translucent to foggy to opaque) Decreased surface area (by about half)

How big is a roll of aerogel SpaceLoft?
