What is Aerogel and Why Might It Be Good for Insulation?


Your building’s energy-efficiency has a lot to do with the quality of its insulation. Even if you have top-of-the-line windows and an ENERGY STAR rated HVAC system, your building is only as efficient as the materials surrounding it.

Aerogel is a unique material that can be used to insulate air ducts, pipes, and other building elements. Aerogel was first developed in 1931 by Samuel Stevens Kistler, but it wasn’t until the 1990s that aerogel became a viable option for commercial use. Even today, aerogel remains one of the most effective insulators on the market. If you want to learn more about aerogel and its uses for insulation, keep reading below! Here’s what we’ll cover:

What is Aerogel?

Aerogel is a synthetic material that is both a solid and a liquid at the same time. Aerogel itself is made from a gel that has been frozen and dried, resulting in a low-density solid that’s hundreds of times less dense than glass (or other common insulation materials like fiberglass). It’s often called “frozen smoke” because it looks like nothing you have ever seen before.

Aerogels are also known as “solid smoke” due to their incredible ability to trap air within their property making them great insulators for homes or other buildings – especially those with high wind flow coming through them due to being on top of tall buildings or hillsides where there may be stronger winds blowing past them than in other areas away from these types of structures.

Aerogel is regarded as the world’s lightest solid. But the production of aerogel materials is quite difficult. The process requires high surface area with accurate temperature and pressure. It is ideal materials for thermal insulation.

What Makes Aerogel Good for Insulation?

Aerogel is a synthetic substance that is made from silica gel, which is a type of glass that is created through a process called supercritical drying. Although it is a synthetic material, it is still considered a natural substance because it is made from a natural material.


Does Aerogel Really Work in Practice?

Aerogel is a good insulator, but it’s not perfect. For example, when building a home that requires heat in the winter and cool air in summer, you should use more than just aerogel insulation to keep your home comfortable. Instead, consider using several different types of insulations together. Aerogel cannot replace other types of insulation—it works best as part of an overall system that includes other materials like fiberglass or cellulose-based products.

Other considerations include climate and location. In places where it gets very hot during certain parts of the year (like Phoenix), homeowners might want to consider adding another type of insulator like spray foam on top of their aerogels so they don’t get too hot inside their homes during those months.

How is Aerogel Created?

Aerogel is a synthetic material that has been produced since 1931 from a process known as supercritical drying. In this process, water is extracted from a gel and left behind as a solid. The resulting material has the consistency of a gel and can be used for insulation purposes.

Aerogel may be an ideal option for insulating your pipes and ductwork due to its high R-value, low weight and lack of toxicity.

Aerogel may be an ideal option for insulating your pipes and ductwork due to its high R-value, low weight and lack of toxicity. Aerogel is a highly insulating material that is lightweight, non-toxic and has a very high R-value (a measure of thermal resistance). It also exhibits superior sound dampening characteristics and can be used in a variety of applications such as soundproofing, insulation for electronics, thermal management in computer servers, desiccant cartridges/packets for food preservation, as well as flame retardant materials.

Pros of Aerogel Insulation

  • High R-value. Aerogel has a high R-value, which is a measure of its ability to insulate. The higher the R-value, the better it will insulate your home or office.
  • Low weight. Aerogel is extremely lightweight and easy to install, making it a great choice for insulation in areas that need some help but don’t have much space to work with—like pipes or ductwork! And because it’s so lightweight, you can also use aerogel in places where other forms of insulation might be too heavy (like ceilings).
  • No toxicity. With plenty of options out there today that are safe for you and your family members, why wouldn’t you consider using an eco-friendly product like aerogel? It’s nontoxic, safe for pets and children (and humans!), won’t irritate sensitive skin like some other materials will do over time—and best of all: It works!
  • Easy installation process makes aerogel perfect for DIYers who want fast results without spending too much money on professional services like carpentry services from [carpenter].

Aerogel vs. Other Insulators

Aerogel is one of the best insulators because it has a high R-value and low weight.

Aerogel’s microscopic lattice structure gives it an extremely open structure and very low density, allowing air to pass through without resistance (like a sponge). Its high R-value makes aerogel a great insulator for keeping heat inside in winter or for blocking out heat in summer. Aerogels also have better thermal conductivity than normal glass insulation materials, which means that more heat can flow through them (and less will be trapped). This property makes aerogels ideal for use in windows and skylights where you want to keep the sun’s rays out during the day while still letting natural light shine through at night when it’s dark outside.

Potential Applications for Aerogel

While we’re just beginning to scratch the surface of aerogel’s potential applications, here are a few examples of how it could be used in everyday life:

  • Home insulation. Aerogel can be used as a replacement for traditional insulation materials, such as wool and cotton. The fact that it’s so light means that its bulk density is very low—the same thickness of aerogel will have a higher insulating power than the same weight of other insulating materials. This means it will take up less space in your home or office building, but still provide enough warmth to keep you comfortable inside!
  • Industrial-grade firefighting equipment. Firefighters already use anaerobic carbon dioxide foam extinguishers to put out small fires like those caused by kitchen grease fires or electrical malfunctions (though these types of extinguishers aren’t effective against chemical fires). Aerogels could be added to this kind of foam solution so that it would absorb heat from any nearby source: from small kitchen appliances like microwaves and stoves; from bigger appliances like refrigerators; even from people who accidentally get too close while trying to escape! This would allow firefighters using this mechanism to fight larger-scale blazes than ever before possible without risking their own lives by getting too close themselves…

How is Aerogel Created?

Aerogel is created by first taking a gel and then subjecting it to supercritical conditions. During this process, the gel is exposed to extremely high pressure and temperature, which causes the gas molecules in the gel to expand. This expansion creates tiny pores in the gel, which allow the aerogel to trap air molecules. Carbon aerogels are made by adding carbon dioxide to the gel during the supercritical process.

Pros of Aerogel Insulation

Aerogel insulation is made from aerogel, which is a type of material with very low density and high thermal conductivity. It is also hydrophobic, meaning that it does not absorb water. Aerogel insulation is the lightest type of insulation available, and its physical properties make it an excellent insulator. It can be used to insulate everything from homes to vehicles, and it is very effective at keeping things cool in hot weather and warm in cold weather.

Potential Applications for Aerogel

Aerogel has many potential applications, both inside and outside of the home. For example, because aerogel is an excellent insulator, it can be used to help keep homes and buildings warm in winter and cool in summer. Additionally, aerogel can be used in NASA rover missions to Mars to help insulate the rover from extreme temperature changes. Finally, aerogel blankets have also been used successfully to insulate people suffering from hypothermia.

Aerogel flexible insulation blankets

Aerogel is a flexible insulation blanket made from aerogel insulation. It is embedded on the structure of melamine foam and other foams. Aerogel insulation is made from a variety of materials, including silica, alumina, and zirconia.

One of the most significant advantages of a foam over an aerogel is that it’s easier to make. Foam can be formed by introducing a gas into polymer as it solidifies, whereas aerogels are created through supercritical drying (a process which forces liquid CO2 through a gel).

Aerogels are much harder to produce than foams. Foams can be made by adding a gas to polymer as it solidifies, but aerogels are made through supercritical drying, which uses liquid CO2 to dry the gel.


Aerogel is a fascinating new material, with many potential uses. It has been used as insulation in some of NASA’s space shuttles, and it may be an ideal option for insulating your pipes and ductwork due to its high R-value, low weight and lack of toxicity. Although more research needs to be done on the material’s long-term effectiveness, it seems to be well worth trying.
