What is the function of insulation in ductwork?

Insulation in ductwork primarily serves to prevent energy loss during air distribution throughout a building. When heated or cooled air travels through ductwork, it can lose its temperature due to heat exchange with the surrounding environment, especially if the ducts are located in unconditioned spaces like attics or basements. Proper insulation helps maintain the temperature of the air as it moves through the ducts, ensuring that the HVAC system operates more efficiently and effectively.

This energy conservation aspect is crucial not only for maintaining comfort levels inside a building but also for reducing energy costs and minimizing the carbon footprint associated with heating and cooling. Insulation effectively acts as a barrier, keeping the air inside the ducts at the desired temperature and preventing energy waste.
