Air barriers

Air barriers are materials or systems installed in buildings to prevent unwanted air movement through walls, roofs, and floors. They improve energy efficiency by reducing drafts, heating and cooling costs, and help maintain indoor comfort. Air barriers also protect the building structure from moisture and humidity-related damage. Typically made of specialized membranes or constructions, they are strategically placed in the building envelope to control airflow, ensuring that only controlled ventilation occurs. Properly installed air barriers are essential for creating a well-insulated, durable, and energy-efficient building environment.
