Types of Garage Door Threshold Seals

There are several types of garage door threshold seals available, each with its unique characteristics and advantages:

Vinyl threshold seal: Vinyl seals are commonly used for residential garage doors due to their flexibility, durability, and low cost. They come in various shapes and sizes to fit different door models.
Rubber threshold seal: Rubber seals offer excellent sealing properties, providing a tight barrier against water and air infiltration. They are also resistant to extreme temperatures and wear and tear.
Brush threshold seal: Brush seals consist of a row of dense bristles that brush against the floor, effectively preventing dust, dirt, and insects from entering the garage. They are often used in commercial applications.
Bulb threshold seal: Bulb seals feature a bulbous shape that creates a tight seal against the floor. They are made of durable materials such as rubber or vinyl and are suitable for heavy-duty use.
