The Insulation packet should be able to withstand up to 700 degrees. The normal operating temp is 350 degrees. When the CU fails(leak or blockage) is when the flue temp can reach over 700 degrees. So, NO, you cannot use fiberglass insulation. Since I rarely use after market Cooling units, the Dometic and Norcold units come with the insulation. Are you positive the CU your using has no insulation? If so, contac the people you purchased from and see if they offer the insulation pack.
