How Does Fiberglass Insulation Work?

Fiberglass insulation works by trapping air within its fine, glass-like fibers, creating a thermal barrier that regulates temperature. The material’s ability to resist heat transfer stems from its composition, where tiny pockets of trapped air impede the movement of heat.

Moreover, the insulation’s composition also aids in sound absorption. As sound waves encounter the fibrous structure, they get disrupted and absorbed, leading to a quieter indoor environment.
