Frequently Asked Questions

How do I calculate pipe insulation?

Measure the total length of pipes to insulate and note the pipe diameter. Our calculator uses these measurements to determine the number of insulation sleeves or linear feet of material needed.

What thickness of pipe insulation do I need?

For most residential applications, 1/2 to 1 inch thick pipe insulation is sufficient. Hot water pipes in unconditioned spaces may benefit from thicker insulation for greater energy savings.

Should I insulate hot water pipes or cold water pipes?

Insulate both for maximum benefit. Hot water pipe insulation reduces heat loss and energy costs. Cold water pipe insulation prevents condensation and freezing in cold climates.
