The uppermost seal affixed to a garage door, typically made of rubber or vinyl, prevents the ingress of elements such as rain, snow, wind, and pests. This barrier is fitted to the top edge of the door panel and presses against the garage lintel when the door is closed.
Protecting the interior of a garage from weather damage is a primary function of this essential component. By creating a tight seal, it safeguards stored items, vehicles, and the structure itself from moisture, drafts, and temperature fluctuations. Over time, this preventative measure can contribute significantly to maintaining the overall value and integrity of the property. This type of sealing mechanism has evolved alongside garage door technology, improving in materials and design for increased effectiveness.
