Insulation for hot and chilled water pipes is a generally common practice for saving thermal energy. The initial cost of the insulation is not high relative to the savings and reduction in gas or diesel bills. Installation of piping insulation is an essential procedure followed during piping installation but if not initially installed it may require some extra cost when being installed on already existing piping. Insulation is sensitive to moisture and other surrounding impacts or vibrations, which requires scheduled checks and replacement for damaged parts to maintain insulation efficiency.
