Because there is so much variation in the applications and products for pipe insulation, it’s challenging to make general comparisons among different types. The best pipe insulation for any given job is largely determined by certain application specifications, rather than product benefits.

Critical, job-specific variables to consider include:

  • Process temperature
  • Compressive resistance
  • Corrosion
  • pH
  • Fire performance
  • Water vapor permeability

More resources for choosing pipe insulation

Referring to product specification sheets from individual manufacturers is still the best method for choosing the correct insulation for each particular project. Additionally, these resources can help inform your decision.

Product comparisons

The National Insulation Association (NIA) has a helpful insulation comparison overview chart, that provides a good first-cut comparison among different insulation types for piping and industrial applications.
