What Are the Different Types of Weather Stripping For Garage Doors?

The door of your garage does a lot to protect your vehicle and your home. It serves as the first line of defense against the elements, and its weather seals shield your garage against rain, debris, dirt, and pests. Weatherstripping not only keeps these threats out of your garage but also prevents moisture and cold air from seeping into the garage door’s crevices. This saves you money on your energy bill by keeping the garage warmer in the winter. There are many types of garage door weather seals, and the right one will depend on the type of door you have. This article will explain your different weather seal options.

Bottom seals

Bottom seals are the most common type of weatherstripping used on garage doors. The flexible rubber seal is slid into the retainer nailed or attached to the bottom of the door. The rubber seal acts as a barrier that seals the gap between the bottom of the door and the garage floor. Wooden garage doors generally do not require retainers—the bottom seal is nailed straight on the lower edge.

Bottom seals are categorized into four types:

J-Type – When the door is closed, the J-type makes two “J’s” on both sides, and it is also utilized in single-channel retainers.

T-Type – The T-type seal is an inverted “T,” as the name suggests. It works just like the J-type seal and is used with single-channel retainers.

Bulb – Bulb seals are long, circular tubes with a tiny opening at the top. They are commonly seen in single-channel retainers, and the design allows the seal to push upward and spread out across uneven cement floors.

Beaded – Beaded seals are used exclusively for double channel retainers. To fit inside the circular grooves, both sides of the strip are bent upwards, preventing water from running under the seal.

Side and top seals

Top and side garage door weather seals are made of PVC, and they are fastened to the doorjamb around the sides and top of the garage entrance. The seal’s flap pushes against the door when the garage door closes, creating a tight seal around the sides and top. These can seal the gaps along the three sides of the door, but they will not seal the gaps along the bottom of the door.

Vinyl door stops are pieces of plastic that go along the sides of the garage door. Vinyl is typically nailed into the wood and forms a watertight seal from top to bottom as garage doors can shift after installation.

Threshold seals

A threshold seal provides excellent protection when used in combination with bottom seals. They are typically made of a flexible strip of material or hard aluminum. They are secured to the garage floor just behind the garage door using strong adhesives or concrete fixing screws. A threshold seal provides a watertight seal when the garage door is closed, even if the floor is not level or the bottom seal has become worn.

Brush seals

Brush seals are basically a brush attached to the door’s bottom. These are typically utilized in high-friction locations or on bending and flexing doors. They’re usually found on the sides of garage doors. They are more frequently used in commercial applications due to their durability. While they are excellent at keeping out hard debris, they are far less effective as a bottom seal in stopping water leaks. But brush seals outperform most other forms of garage door seals when it comes to side seals.
