Vinyl seals are among the most common types of bottom garage door seals. These seals are flexible, durable, and resistant to extreme temperatures, making them ideal for varying climate conditions. Vinyl seals typically come in a T-shaped profile, which allows them to fit snugly against the floor, preventing drafts, water, and dirt from entering the garage. They are easy to install and can be cut to fit different garage door sizes. One noteworthy advantage of vinyl seals is their cost-effectiveness, making them a popular choice among homeowners.
