The component affixed to the lower edge of an upward-acting residential or commercial entry closure is designed to create a weather-resistant barrier. Typically constructed of rubber or vinyl, this element closes the gap between the door and the floor. For example, a worn or damaged part may allow drafts, water, and debris to enter the structure.
This element serves a crucial function in maintaining energy efficiency, preventing pest intrusion, and protecting stored items from the elements. Its proper installation and maintenance contribute significantly to a comfortable and secure environment within the enclosed space. Historically, simpler methods were used to seal this area, but modern materials offer improved durability and effectiveness.
