A barrier affixed to the edges of a garage door, typically made of rubber, vinyl, or other flexible materials, closes the gap between the door and its frame. This closure prevents the ingress of air, water, dust, and pests. Examples include bottom seals, top seals, and side seals, each designed for specific areas of the garage door.
Maintaining a properly functioning barrier offers several advantages. It improves energy efficiency by reducing drafts, leading to lower heating and cooling costs. Protection from the elements extends to safeguarding stored items from moisture damage and pest infestations. Furthermore, it minimizes noise infiltration, creating a quieter environment within the garage and adjacent living spaces. While the specific materials and designs have evolved over time, the basic principle of sealing garage doors against the elements has been a practical necessity for decades, growing in importance with increasing energy costs and comfort expectations.
