Aerogel insulation felt is a kind of insulation material made of glass fiber and aerogel as the main material. As a new type of insulation material, aerogel insulation felt has attracted much attention in the fields of fire prevention, heat insulation, sound absorption and so on, and has a broad application prospect.

First, the advantages of aerogel insulation felt
1, excellent thermal insulation performance
The interior of aerogel insulation mat is a nanoscale porous structure with high porosity and small pore size, which can effectively block air circulation. In addition, the thermal conductivity of aerogel insulation felt is low (0.012~0.025W/m·K), which is 2 to 3 orders of magnitude lower than the traditional thermal insulation material, so it has excellent thermal insulation performance. Excellent thermal insulation performance can reduce energy consumption, thereby saving energy and saving costs.
2. Ultra-low density
Aerogel felt has a very low density, usually between 100 and 500kg/m³, so it is very light and easy to transport and install, but also brings great convenience to the construction process, reducing the self-weight load of buildings and equipment.
3, high temperature stability
Aerogel insulation mat belongs to class A non-combustible material, which can maintain stable performance in high temperature environment, has good fire resistance, and can withstand high temperature above 1000℃.
4, good sound absorption performance
Because of the porous structure of aerogel insulation felt, it has good sound absorption performance, and has a good effect on noise control and isolation.
5. Environmental protection and sustainability
Aerogel felt is generally made of inorganic materials, does not contain harmful substances, is environmentally friendly, and no toxic substances are produced during use.

Second, the disadvantages of aerogel insulation felt
1. High cost
Compared with traditional thermal insulation materials, the production cost of aerogel thermal insulation felt is relatively high, so the price is more expensive.
2, the tensile strength is low
The mechanical strength and tensile properties of aerogel insulation felt are relatively low, and it is easy to be affected by external forces.
3, high construction technical requirements
In order to achieve the best insulation effect, the construction of aerogel insulation felt requires expertise and experience. If the construction is not proper, it may lead to a great loss of thermal insulation performance.
The advantages of aerogel insulation mat include ultra-low density, excellent thermal insulation and sound absorption performance, high temperature stability and environmental sustainability, but it also has the disadvantages of high cost, low tensile strength and high construction technical requirements.
