Fiber glass wool is widely used for thermal and acoustic insulation in buildings, industrial equipment, and HVAC systems. Its fine fibers trap air, creating an effective barrier against heat transfer, helping maintain indoor temperatures and reduce energy costs. It is commonly installed in walls, ceilings, and roofs of residential and commercial structures. In industrial settings, fiber glass wool insulates pipes, boilers, and tanks operating at high temperatures, improving energy efficiency and worker safety by reducing surface heat. Due to its sound-absorbing properties, it is also used in noise control applications such as in walls, partitions, and ceiling panels to dampen airborne and impact noise. The material is non-combustible, resistant to mold and moisture, and does not settle over time, making it a durable and reliable insulation solution. It is often used in fire-rated assemblies due to its ability to withstand high temperatures without contributing fuel to a fire.
