The answer to 'difference between ductwork and' is that ductwork refers to the system of pipes and vents that carry heated or cooled air throughout a building, while insulation is the material used to wrap and protect the ductwork. Ductwork is essential for an HVAC system to properly distribute air, while insulation helps maintain the temperature and prevent energy loss.
Ductwork is typically made of sheet metal, flexible plastic, or fiberglass, and is installed within walls, ceilings, and attics. It connects the HVAC unit to the vents and registers in each room. Insulation, on the other hand, is wrapped around the ductwork to reduce heat transfer and keep the air at the desired temperature as it travels through the system. Proper insulation can improve energy efficiency and lower utility bills.
