At Firwin Corporation, we specialize in finding the best insulation materials and designs for your specialized equipment and unique applications. Our comprehensive selection of insulation materials ensures that we will find the perfect insulation solution for your needs. One of Firwin’s most versatile insulating materials is Aerogel, a porous, solid material with a high percentage of air and a variety of unique properties.
Aerogel is a class of low-density solid gels in which the liquid has been replaced with air or gas. The structural framework of Aerogel is typically composed of silica, so silica aerogel is often referred to as simply “Aerogel.” However, other structural materials have been used to create aerogels, including:
Regardless of the material, the preponderance of air in an Aerogel’s structure gives it a nearly transparent appearance. The high gas content of Aerogels also gives them a variety of unique properties, including extremely low density, very low thermal conductivity, and very high porosity.
In insulation applications, Aerogel easily outperforms traditional fillers such as wool and fiberglass. In fact, Aerogel offers the same quality insulation with 1/3 the thickness of other insulating materials. However, Aerogel is expensive to manufacture and is rigid and brittle in its basic form, so it requires some supporting material. In addition, Aerogel withstands temperatures up to °F (593 °C), but is not suitable for extremely high-temperature applications that operate above that level.
Silica Aerogel is particularly useful for insulating applications and is one of the most effective insulators available. Although it is more expensive than other insulating materials, Aerogel makes up for its cost by the benefits it offers. Some of these include:
Aerogel has been used as an insulating material for decades. Most notably, it has been used in NASA spacesuits for its exceptionally lightweight and durable nature. As manufacturing technology advances, Aerogel has become increasingly desirable in a broad range of insulating applications, including:
Although Aerogel is typically more expensive than other insulating materials, its enhanced thermal insulating properties with thinner layers make it uniquely suited for confined spaces. In addition, its extremely lightweight characteristics make it ideal for use on light and breakable components that could be damaged by the weight of more traditional insulating materials.
