In this video, we will explore the performance of 120g fiberglass coated mat with different coverage rates. We have two types of fiberglass coated mat here, one with a poor coverage rate and the other with a good coverage rate.
For the fiberglass coated mat with a poor coverage rate, in terms of air permeability, there are more pores between the materials like Fiberglass Coated Mat, which is similar to Fiberglass Veil in some aspects. This allows for better air circulation, which is beneficial in scenarios such as Acoustic Ceiling Surface or Acoustic Wall Panel Facer where ventilation is important. It helps control humidity and temperature in indoor acoustic environments and affects the acoustic effect. However, in terms of appearance and protection, the poor coverage rate means the core material may be visible through the mat, and it may not provide sufficient protection against external factors like dust and moisture. This can also affect the overall protection performance and aesthetics in the application of Glass Fiber Felt For Sound Absorption Ceiling Panels.
For the fiberglass coated mat with a good coverage rate, it can effectively cover the core material completely. Acting like Fiberglass Coated Fleece in some ways, it serves as a barrier to protect the core material from ultraviolet radiation, chemical erosion, and physical wear, especially in applications like Acoustic Ceiling Surface or Acoustic Wall Panel Facer. This improves the overall aesthetics and prolongs the service life of the core material. Although it may sacrifice some air permeability compared to the one with a poor coverage rate, in applications where a high covering rate is required, such as in the decorative outer layer of building materials and in Glass Fiber Felt For Sound Absorption Ceiling Panels, it can better protect the internal structure and maintain stable acoustic performance.
