The flexible material affixed to the lower edge of a garage door, typically composed of an elastomer, forms a critical barrier against the elements. This component addresses the gap between the door and the floor, preventing ingress of water, debris, pests, and air. A common application sees this weather stripping secured via a retainer along the door’s bottom edge.
Effective closure at the base of a garage door yields several advantages. Reduced energy consumption due to minimized drafts is a primary benefit. Protecting stored items from moisture damage and deterring rodent entry contributes to a safer, more secure storage environment. Historically, simpler materials like wood were used; modern elastomers provide superior flexibility, longevity, and resistance to environmental degradation.
