Glass cotton blanket is a common thermal insulation material, made of glass fiber as raw material, with good light weight, heat insulation, sound insulation, fire prevention and other characteristics. In the construction and industrial fields, glass wool felt is usually affixed with aluminum foil to improve the insulation effect. However, many people will ask: Do you need additional waterproof treatment after the glass wool felt is affixed to the aluminum foil?

First of all, let's look at the performance of aluminum foil. Aluminum foil itself has a certain moisture-proof performance, which can reduce the penetration of water. At the same time, aluminum foil can also provide a certain insulation effect. Therefore, in some cases, there is no need for additional waterproof treatment after the glass cotton blanket is affixed with aluminum foil.

However, if under certain circumstances, such as in a high humidity environment or exposure to water sources, in order to further improve the moisture resistance, you can consider taking waterproof measures. Waterproofing treatment can be applied with waterproofing paint and waterproofing layer to enhance its waterproofing performance and ensure its performance and service life.

It should be noted that different use environments and needs for waterproof requirements are also different. Therefore, when carrying out waterproof treatment, it is necessary to evaluate and select the appropriate waterproof scheme according to the specific situation. At the same time, special waterproof treatment is also needed for the glass cotton roll felt aluminum foil materials used in some special environments, such as close to water sources and easy to be damp.

Whether additional waterproof treatment is required after the glass cotton roll felt is affixed to the aluminum foil depends on the specific use environment and needs. In the selection, it is necessary to consider various factors comprehensively and take appropriate measures to ensure that the excellent properties of the material are maximized.
