Even when the garage door is closed, you can sense drafts, and the temperature isn’t stable. Slam the door shut. Your door’s weatherstripping may be at blame if the draft persists.

The R-value of a door is sometimes misunderstood as the only metric for determining its level of insulation. What good is an R-value often if there is just an inch of room on each side of the door to insulate? The airtightness of the weatherstripping is the key to a good door.

A garage door’s weatherstripping comes in four distinct varieties, each with advantages and disadvantages. Whichever one is to blame must be isolated.

1. Your Garage Door’s Bottom Weatherstripping

If the weatherstripping on your home needs to be replaced, look no further than here. The bottom weatherstripping is often two sections with a PVC or aluminum support and a rubber strip. The rubber part of the joint is often the source of issues since it may become broken or too hard, making it incapable of staying flexible. If your bottom weatherstripping is broken, dried out, discolored, or drooping, it’s time to replace it.

  • The bottom of your door’s weather seal comes in various varieties. Take a peek at these.
  • The bottom weather seal may also fail if Water Accumulates beneath the garage door. If your garage’s entry floor is uneven or broken, this might happen. Lower temperatures might cause ice to build upon the door, resulting in a jam and eventual failure of your electric opener.
  • The damage might be inflicted on your garage because of a bit of water dripping from the door.

There are two ways to go about fixing this. 

  • Before the water freezes, start by spreading sand beneath the entrance. While salt would corrode the rubber and concrete, this solution will keep the door from sticking in the frame.
  • Sand, on the other hand, is merely a short-term fix. The ice will attach to the door again when the sand is moist enough.

2. The Garage Door’s Perimeter Weatherstripping

If the door was installed incorrectly, the rubber might have continually scraped against the door and been worn and damaged.

  • It might be torn or unable to return to its original form.
  • Parallel to the wall, the installed door is not recessed. Weatherstripping is a filler for the space between the door and the wall. The most common material for the supports is PVC. However, they may also be constructed of metal.
  • Using PVC instead of metal is mainly cosmetic since the screws on the aluminum supports will not be concealed. The usage of aluminum brackets on dark-colored doors is more common. Due to its weak heat resistance, PVC supports are no longer available in light colors. Because of the sun’s heat, black supports, for example, might twist and contract.

3. The Garage Door’s Top Weatherstripping

The top of the door may be weather-stripped. However, this is not a common feature of garages. Commercial doors, bigger than residential ones, are more likely to have a header weather seal installed.

  • Unless the garage is utilized as a workshop or has to be kept very warm During The Winter Months, weatherstripping around the top of a residential door isn’t usually essential.
  • Due to the polyurethane insulation’s thermal break between the inside and outside of the door, a temperature difference will exist between the two. While icy metal tends to shrink, hot metal tends to expand. Due to the insulation, heat will not be transferred between the two sides of the door, preventing it from bending.

4. In-between-section Weather Seal On Your Garage Door

You’ll find the fourth seal on your door between the door panels. Air, light, and even water cannot travel through joints, which feature three contact points. The whole door must be replaced if a weather seal is damaged. Such an issue is quite improbable with a garage door.

The weather seal is no longer effective if a piece of paper can be slipped between the panels.

Bottom Line

It’s more challenging to discern whether the doors and windows in your garage require weatherstripping than determining if any of the rooms in your home are prone to heat loss. During the cooler months, it’s critical to inspect your garage door for indicators that the Weatherstripping Needs To Be Replaced. A drafty garage is inconvenient, but it can also be costly.

Garage doors may come off the track, panels can bend, gate openers can malfunction, springs can break, and tracks or brackets can be damaged.
