What is aerogel?


Aerogel is a type of solid material that is extremely lightweight and has a low density. It is also known as “frozen smoke” or “solid smoke” because of its translucent appearance and low density. Aerogel is made by removing the liquid component of a gel through a process called supercritical drying, which leaves behind a solid structure made up of a highly porous network of particles.

Aerogel has a number of unique properties that make it useful in a wide range of applications. It is an excellent insulator, with a very low thermal conductivity. It is also hydrophobic, meaning it repels water, and is able to withstand high temperatures. It is also a very good sound insulator. Aerogel is also a good electrical insulator.

Due to its unique properties, aerogel has been used in a variety of applications such as insulation in construction, insulating clothing, oil spill cleanup, and space technology. In space technology it is used in thermal insulation and radiation protection on spacecrafts and in rovers.

Aerogel can also be used in various scientific experiments, such as in the detection of cosmic dust particles. Additionally, aerogel has potential for use in fields such as catalysts, energy storage, and biomedical applications, among others.

Whether airgel is used as insulation for houses?

Aerogel has been used as insulation in construction, and it is known for its excellent insulation properties. Due to its low thermal conductivity, it can help to reduce heat loss in buildings, making them more energy efficient. Aerogel can be used as insulation in walls, roofs, and floors, and it can also be used in double-glazed windows to improve their thermal performance.

Aerogel insulation can be used in a variety of different forms, such as blankets, panels, and beads. It can also be used in combination with other insulation materials, such as fiberglass, to enhance their insulating properties.

However, it should be noted that aerogel is a relatively new technology, and it is still relatively expensive compared to other insulation materials. Additionally, it is fragile and brittle, so it may not be suitable for all applications.

The use of aerogel in houses insulation is not widespread yet. But it’s been considered for use in new construction or retrofitting of existing buildings due to its high insulation properties. The cost of aerogel is still a barrier to its widespread use in the construction industry, but research is ongoing to develop more cost-effective aerogel products.

How much does airgel for home insulation cost?

The cost of aerogel insulation for home insulation can vary depending on the type of aerogel used, the form it comes in, and the quantity purchased. Aerogel insulation is still relatively expensive compared to other insulation materials.

As a rough estimate, the cost of aerogel insulation in the form of blankets or panels can range from $5 to $10 per square foot. This is significantly higher than traditional insulation materials such as fiberglass or cellulose, which can cost around $0.50 to $1.50 per square foot.

However, costs have been decreasing in recent years as more companies are entering the market and production has been scaled up, so it’s worth checking with different suppliers for the most recent prices. Additionally, it’s worth considering that, although the upfront cost of aerogel insulation is higher than other materials, it can help to save on energy costs over the long term, which may offset the initial expense.

It’s also important to note that the cost of aerogel insulation can vary depending on the region, the availability of the material, and the type of application, it’s best to consult with an architect to get an estimate of what it would cost to insulate your specific home.
