Foam-Tite insulation Tape provides the service technician with a quality yet economical solution to one of the most common HVACR application problems: sweating or condensation on air conditioning, refrigeration, chilled water or other cold lines. Because of its excellent insulation properties, it can also be used on hot water lines for insulation against heat loss. Keeps cold lines cold and hot lines hot. It can be overlapped or the edges can be butted. The amount of tape that will be required and the style of wrap (over-lapped, butted or both) will depend upon relative humidity, ambient temperature and the temperature of the pipe to be covered. Service temperatures can be as low as -15ºF with a high continuous temperature of 160ºF.
