Methods for distinguishing the quality of glass wool felt

There are two main methods to distinguish the quality of glass wool felt. The first one is to distinguish from the strength and uniformity of the surface layer. Such a glass wool felt material can ensure the fire resistance of the glass wool felt material to a certain extent and the strong density of Chao. In the application process, it can ensure that the fire resistance of the product can be effectively reduced and that the fire resistance of the product will not be affected due to quality problems.

The second method is to distinguish the fire resistance of glass wool felt materials from their standard spacing. Generally, glass wool felt materials made by professional technology do not need you to cut in the later stage, which can reduce the stimulation of glass wool felt debris to human body. After optimized processing, the quality of glass wool felt materials is lighter, and the sound insulation effect of products can be improved by at least 10 dB. It can be used in shopping malls and industries to ensure quality.
