What Is Fiberglass Insulation?
Fiberglass insulation is a type of insulation material produced by melting glass at high temperatures, forming it into fibers, and then solidifying those fibers.
One of its standout features is its excellent insulating properties with low thermal conductivity, primarily attributed to the presence of numerous air layers within the material. In addition to its insulating capabilities, fiberglass insulation is valued for its fire resistance. Moreover, the inherent air pockets contribute to its remarkable sound absorption properties.
Fiberglass insulation finds applications in various fields, including construction and industrial, among others. Specific uses include insulation for roofs, walls, and floors in buildings, as well as insulation for HVAC systems, pipes, sound equipment, automobiles, and more.
There are different types of insulation materials, with two notable variants being conventional glass wool and rock wool, which is crafted from natural basalt fibers. Glass wool is acclaimed for its exceptional fire resistance and insulating properties, while rock wool is favored for its resistance to high temperatures, making it suitable for specialized applications.
