The HVAC roof is a type of roofing system that is designed to provide heating, ventilation, and air conditioning (HVAC) to a building. It is a combination of components that work together to provide a comfortable indoor environment. The components of an HVAC roof include insulation, a vapor barrier, air ducts, and an air handler. The insulation helps to keep the air inside the building at a comfortable temperature, while the vapor barrier helps to keep moisture out. The air ducts provide a way for the air to be circulated throughout the building, and the air handler helps to regulate the temperature and humidity levels. An HVAC roof is an important part of a building’s overall energy efficiency, as it helps to reduce energy costs and improve the indoor air quality.
