A barrier designed to close the gap between a garage door and its frame is essential for protecting the interior from the elements. These barriers come in various materials like rubber, vinyl, or foam, and are attached to the door frame or the door itself. An example is a bottom seal affixed to the bottom edge of the door, creating a tight seal against the floor.
These protective devices offer several key advantages. They prevent drafts, keeping the garage at a more stable temperature and potentially lowering energy costs. They also block out moisture, reducing the risk of mold and mildew growth, and protect against dust, debris, and pests. Historically, simpler methods like felt were used, but modern materials offer superior durability and performance, reflecting advancements in building science and material technology.
