Protecting the garage from the elements involves sealing the gaps between the door and its frame. This is typically accomplished with flexible rubber or vinyl seals fitted along the top and sides of the garage door. These barriers prevent the ingress of water, wind, dust, and pests. For example, a properly installed top seal conforms to the curvature of the door to block drafts and debris, while side seals prevent gaps between the door and the frame.
Effective sealing contributes significantly to energy efficiency by minimizing air leaks, which can lead to temperature fluctuations within the garage. This protection also safeguards stored items from weather damage and helps maintain a cleaner, drier environment. Historically, simple felt or brush-like materials were used. Modern materials and designs offer superior durability, weather resistance, and a tighter seal, reflecting the increased demand for energy-efficient homes and garages.
