Aluminum foil coated glass wool board is a common insulation material, which is mainly composed of glass wool inside and aluminum foil outside. I will analyze it from the following aspects:

　　1. Thermal insulation performance: the thermal conductivity of glass wool is very small, which can well isolate the heat transfer, so the aluminum foil covered glass wool board has good thermal insulation performance. At the same time, aluminum foil surface can also play a better reflection effect, can reflect the heat radiation back, further improve the insulation effect.

　　2. Environmental performance: aluminum foil coated glass wool board does not contain any harmful substances, in line with environmental requirements. In the production process, also adopted environmental protection process and technology, to ensure the environmental performance of the product.

　　3. Fire safety performance: glass wool itself is not flammable, and can prevent the spread of fire, so aluminum foil coated glass wool board in the aspect of fire prevention performance is very good. At the same time, aluminum foil surface also has better fire performance, can effectively prevent fire.

　　4. Functional performance: aluminum foil coated glass wool board can not only have insulation function, but also can have sound insulation, moisture-proof, seismic and other functions. At the same time, because of its good softness, convenient construction, wide range of application.

　　Glass wool itself does not have waterproof performance, but can be treated to improve its waterproof performance. The glass wool board covered with aluminum foil has better waterproof performance. Aluminum foil can effectively prevent water penetration, improve the service life of glass wool.

　　In short, aluminum foil coated glass wool board is a kind of insulation material with good comprehensive performance, with good thermal insulation performance, environmental protection performance, fire safety performance and functional performance, suitable for all kinds of construction and industrial fields. It should be noted that the specific waterproof performance should also be evaluated according to the specifications and environmental conditions used on actual occasions.
