In an HVAC system, a chiller system is used to supply chilled water to the Air Handling Units. The MS pipes carrying this chilled water should be perfectly insulated in order to ensure that this chilled water does not gain heat from the ambience. Therefore, these pipes are insulated with fiberglass wool. In other applications, Fiber Glass Wool is also used to insulate hot water pipes. In certain specific industries, drain pipes and copper pipes are also insulated with Fiber Glass Wool.
