Garage Door Bottom Seal Types & Why Are They Useful

You might have come across the names of various garage door parts, from openers to seals. Each component has an important role; being familiar with them can help you with your garage door maintenance. Seals can come in handy if you’re worried about weather-stripping your garage door. Read this blog to learn about the garage door bottom seal and its types.

Types of Garage Door Bottom Seal

Heavy rain, snowfall, and other elements can damage your garage door, which might cost more than getting bottom seals. Therefore, go for a bottom seal to prevent damage from happening in the first place. Below, we will list four types of bottom seals you can get for your garage door:

1. Bulb-Shaped Seal

The bulb-shaped bottom seal is used for single-channel retainers. It is among the best bottom seal types for your garage door, with a circular-shaped base and a larger T shape at the top. Thus, it has enough room for the seal to spread out and push upwards when facing uneven surfaces. They’re recommended for residential garage doors instead of commercial ones.

2. Beaded Bottom Seal

When dealing with double-channel retainers with circular grooves, beaded garage door bottom seals are useful. Both sides of the strip are bent and face upwards, allowing it to fit into circular grooves. Moreover, the beads prevent the water flow before it can get into your garage from beneath the seal.

3. T-Type Seal

Also used with single-chain retainers, T-type garage door bottom seals have an inverted T. Usually, t-type bottom seals are used alongside single-channel retainers.

4. J-Type Seal

J-type garage door bottom seals owe their name to their shape after they’re fixed on the retainer. You’ll observe that it forms the letter J on each side of the threshold once the door closes. In addition, they are typically used with single-chain retainers. You can also use them to cover the sides of the door to increase weatherproofing. Furthermore, they’re commonly made from rubber and vinyl, as they seal the gap between the garage door and the floor.
