Fireproof Soundproof Indoor Internal And External Wall Silica Aerogel Blanket

Aerogel Blanket for internal and external wall insulation

Aerogel blanket mainly takes aerogel as the core material. Aerogel is a solid material with a nanoscale pore structure. These pores are so tiny that the aerogel felt has an extremely low thermal conductivity. Usually, the aerogel felt is composed by compounding aerogel with fiber reinforcement materials (such as glass fiber, ceramic fiber, etc.). The fiber reinforcement materials can provide certain mechanical strength for the aerogel felt, making it less likely to be damaged during use.
Moreover, its felt-like structure endows it with good flexibility and workability. For example, it can be conveniently cut into different shapes and sizes to adapt to the dimensions and shapes of various walls. It can fit well whether on flat walls or those with a certain curvature

Insulation principle

Based on its nanoscale pore structure, the aerogel felt for internal and external wall insulation can effectively block heat conduction, convection and radiation. Air molecules can hardly flow freely in these tiny pores, which greatly reduces heat convection. Meanwhile, the solid skeleton structure of the aerogel material itself also has a good blocking effect on heat conduction. In terms of preventing heat radiation, the special composition and structure of aerogel can reflect or absorb a part of heat radiation, thus achieving the insulation effect in all aspects.
Compared with traditional insulation materials, the aerogel felt for internal and external wall insulation can achieve the same or even better insulation effect with a thinner thickness. For example, the traditional polystyrene foam insulation board may need a thickness of several centimeters to meet a certain insulation standard, while the aerogel felt may only need a few millimeters to achieve a similar insulation requirement.

Advantages for internal and external wall insulation

• For external wall insulation:
  It can effectively resist the impact of changes in the external environmental temperature on the interior. In cold winters, it reduces the heat loss from the interior to the outside through the external wall, playing a good role in insulation. In hot summers, it can prevent the external heat from entering the interior, reducing the frequency of using air conditioners and achieving the purpose of energy conservation.
  It has good waterproof performance. Especially for external walls, it can prevent rainwater from penetrating into the interior of the wall and avoid damage to the wall insulation layer caused by moisture, thus prolonging the service life of the insulation system.
  Due to the stability of the material and its fireproof performance (usually Class A non-combustible material), it can improve the overall safety of the building's external wall and reduce the risk of fire.

• For internal wall insulation:
  It can provide a good insulation effect without taking up too much indoor space. Its thin feature makes it have less impact on the indoor space after being installed on the internal wall.
  It can effectively balance the temperature differences between different areas indoors. For example, for some rooms close to the external wall or adjacent rooms with temperature differences, using the aerogel felt for internal wall insulation can make the indoor temperature distribution more uniform and improve the living comfort.
