Do I Need to Insulate My Pipe?

Plastic pipe walls offer some natural insulation as plastic is a poor conductor of heat. This is not, however, enough to prevent heat loss in many situations. Pipe insulation should be used in situations where;

The fluid flowing through the pipe has had energy applied to it (in the form of heating or cooling) to change the temperature from the ambient air around it. As well as to retain the temperature as the fluid flows through the pipe, the insulation also reduces energy costs (both financial and environmental).
Pipes that have either low or no-flow for periods where the surrounding air temperature is below freezing, can be prone to freezing and cracking. PVC is the most susceptible of pipe materials for this and shatters easily as the fluid inside freezes and expands. ABS is a little more forgiving and, rather than shattering like PVC, tends to split. PE pipes are the most forgiving and will only occasionally split.
