Insulating hot water pipes helps preserve the temperature of the water in the pipes. The water temperature in insulated hot water pipes can be 2 to 4 degrees Fahrenheit higher than the water would be in uninsulated pipes (source: energy.gov).
This water pipe insulation comes in four 3 foot long sleeves, pre-slit lengthwise, allowing it to be "snapped" onto 1/2" copper water pipes or 1/4" iron water pipes. The foam insulation can be cut with a knife to accomodate turns or shorter lengths of pipe.
Pipe insulation will reduce the rate of heat loss through domestic hot water pipes into the surrounding space. When the temperature of the water in hot water pipes is lower, it can take more time for hot water to flow from a faucet or shower, increasing both water use and energy costs. Insulating the first 9 feet of pipe from the hot water tank will generally deliver the greatest benefit.
Beyond the savings associated with insulating hot water pipes, insulating cold water pipes can prevent exterior condensation on the pipes, insulating water pipes can lower the risk of freezing, and insulating water pipes can help to dampen sounds associated with the water flowing through the pipes.
This pipe wrap insulation consists of four 3-foot long foam sleeves, pre-slit lengthwise, allowing it to be "snapped" onto 1/2" copper water pipes or 1/4" iron water pipes. The foam insulation can be cut at with a knife to accomodate turns or shorter lengths of pipe. With a wall diameter of 3/8", this sleeve pipe insulation has an R-Value of 2.1*.
- Dimensions (1 piece): 1/2" interior diameter hole (ID), 3/8" thick wall, 36" long

* "R-Value" reflects how well a material can prevent the flow of heat through the material. The higher the R-Value, the greater the thermal resistance.
