Fiberglass is commonly used for piping insulation due to its excellent thermal resistance, lightweight nature, and high availability. It effectively reduces heat loss or gain from pipes, which is crucial for maintaining energy efficiency in plumbing and HVAC systems. The insulating properties of fiberglass help to stabilize temperature and prevent condensation, which can lead to corrosion or other issues.

Fiberglass insulation is also relatively easy to install and can be shaped to fit around various piping configurations. Unlike some other options, it does not conduct heat, making it ideal for both hot and cold water pipes. Therefore, its thermal efficiency and practical benefits render it a preferred choice for insulating pipes in a wide range of applications.
