Air seal is a term used in the field of building construction and energy conservation to describe the process of preventing the uncontrolled flow of air through a structure. It refers to the act of sealing gaps, cracks, and openings in a building's envelope or enclosure, such as walls, floors, windows, doors, and ceilings, to minimize air leakage between the inside and outside environment.
The purpose of air sealing is to improve energy efficiency, indoor air quality, and thermal comfort within a building. By reducing the infiltration of outside air and the escape of conditioned air, air sealing helps to maintain a consistent indoor temperature, reduces the workload on heating and cooling systems, and lowers energy consumption. Moreover, it prevents the intrusion of moisture, dust, pollutants, and outdoor noise, promoting a healthier and more pleasant indoor environment.
Common techniques employed in air sealing include caulking, weatherstripping, and the use of sealants or gaskets. These methods are used to seal gaps around windows and doors, seal joints between building components, such as walls and floors, and close openings around pipes, ducts, and electrical penetrations. The choice of air sealing materials and techniques depends on the specific requirements and conditions of the building.
In summary, air sealing is the process of sealing gaps and openings in a building to control the movement of air, improve energy efficiency, and enhance indoor environmental quality.
