The seals located along the bottom, top, and sides of a garage door, within the garage itself, are essential components. These barriers against the elements typically consist of flexible materials like rubber, vinyl, or foam, designed to conform to the door’s shape and block gaps. For instance, a bottom seal might be a heavy-duty rubber strip attached to the bottom edge of the door.
Effective sealing provides several advantages. A properly sealed garage protects stored items from the damaging effects of moisture, dust, pests, and extreme temperatures. It also improves energy efficiency by reducing drafts and minimizing heat transfer, leading to lower utility costs. Over time, materials and designs have evolved from simple felt strips to more durable and effective options, reflecting a growing understanding of building science and energy conservation.
