The rubber or vinyl seal affixed to the lower edge of a garage door plays a vital role in protecting the garage interior. This barrier prevents the ingress of water, debris, insects, and pests, while also enhancing energy efficiency by minimizing drafts. A typical example comprises a flexible material shaped to fit the contours of the door, often incorporating a T-shaped or bulb-shaped end for a secure seal against the floor.
Maintaining a tight seal at the base of the garage door is crucial for several reasons. It safeguards stored items from weather damage and pest infestations, contributes to a more comfortable interior temperature, and can reduce energy costs. Historically, simpler materials like felt or brush-like seals were used, but advancements in polymer technology have led to more durable and effective solutions. These modern seals offer superior resistance to wear and tear, temperature fluctuations, and UV exposure, contributing to a longer lifespan and better performance.
