What type of pipe insulation works better Armaflex Foam or Fiberglass?

Armaflex foam insulation is generally better for applications requiring flexibility, moisture resistance, and lower thermal conductivity, making it ideal for HVAC systems and cold piping. Fiberglass insulation, on the other hand, is more suitable for high-temperature applications and provides Excellent sound dampening. Ultimately, the best choice depends on the specific application and environmental conditions.
