    About Selecting Thermal Insulation
    industrial info icon

    Compare R-value and temperature range to find the insulation material that best suits your application.

    Ultra-Thermally-Insulating Polyisocyanurate Foam Pipe Insulation

    Our best pipe insulation for maintaining temperatures. Use it on long runs where temperatures must stay constant, such as in refrigeration systems or to move liquified natural gas. Polyisocyanurate insulation resists moisture, so it maintains its thermal performance and prevents corrosion underneath.
