COLD INSULATION

Cold Insulation is a type of insulation required for environment temperatures below ambient, which is typically capable of preventing condensation, moisture intrusion and long term degradation. Moisture from condensation is a problem in any cold system

Materials used for cold insulation vary dependent upon the systems that are being insulated. Two common materials used in cold insulation are:

  • Polyurethane Foam: Perfect for handling low thermal conductivity and substances with below freezing temperatures. Polyurethane foam also allows for low smoke emission and low water vapor permeability.
  • Rubber Foam: Rubber foam is also often recommended for condensation control as the closed cell technology is highly resistant to moisture vapor.

With chilled insulation, keeping the cold in is as important as keeping the heat out. There are many types of insulation than could be used on chilled systems, i.e. pipes, tanks, etc. The two most popular are foam glass and rubber insulation or Armaflex. Although a little more challenging to work with than pre-molded fiberglass, but when installed correctly, these materials do a great job of stopping condensation and preventing energy loss.
