In the field of energy saving, thermal insulation boards are commonly used materials. For some specific cases, some insulation boards will add a layer of aluminum foil on their surface, which is not a simple decoration, but to improve the insulation effect and enhance the performance of the material. Next, Xiaobian will explain the role of aluminum foil on the insulation board.

1, reflect heat radiation, improve the insulation effect

Aluminum foil has excellent reflective properties and can reflect most of the thermal radiation. When the building surface is exposed to sunlight, part of the thermal radiation is reflected, reducing the absorption of heat. Therefore, the aluminum foil on the surface of the insulation board plays the role of a thermal insulation barrier, effectively reducing the conduction of heat and improving the thermal insulation performance of the building.

2, moisture-proof and waterproof, enhance the durability of the insulation board

The aluminum foil itself has a certain moisture-proof performance, which can prevent the water vapor in the air from penetrating into the interior of the insulation material, and play a certain moisture-proof role. In addition, the surface of the aluminum foil is often covered with a waterproof film, which further enhances the waterproof performance of the insulation board and extends the service life of the insulation board.

3, enhance mechanical properties, improve stability

Aluminum foil can increase the mechanical strength and stability of the insulation board, making it more durable and easy to install. The existence of aluminum foil can effectively prevent the damage and deformation of the insulation board in the process of transportation, installation and use, and ensure the stability and safety of the building structure.

In addition to the above functions, aluminum foil also has fire resistance and certain protective properties. As a fireproof material, aluminum foil can enhance the fire resistance of the insulation board and improve the safety of the building. In addition, aluminum foil can also be used as a protective layer to protect the insulation board from external damage.

The aluminum foil on the insulation board has multiple functions such as moisture proof, heat insulation, heat preservation, fire prevention and waterproof. It can not only improve the performance of the insulation board, extend its service life, but also provide a more comfortable, safe and energy-saving environment for the building.
