Insulation for air-conditioning systems
Air-conditioning uses several kinds of insulation: external duct wrap to keep the cold in and stop condensation, internal duct liners to reduce air and fan noise, insulated flexible ducts for the runs to diffusers, and insulation for refrigerant and chilled-water pipes.
