air leaks
Gaps letting drafts
Air leaks are unintended gaps or openings that allow air to pass through a barrier—typically in buildings, vehicles, or sealed systems.
In homes, air leaks around windows, doors, and ductwork reduce energy efficiency: We sealed the air leaks in the attic to lower our heating bills.
In pressurized systems like tires or pneumatic equipment, air leaks cause gradual pressure loss.
