The energy efficiency of a home greatly depends on its airtightness, especially when it comes to the garage door, which is often the largest opening in a home. In this article, Garex guides you on how to choose, maintain, and most importantly, install perimeter weather seals for your garage door.

Why is It Important to Install a Weather Seal on Your Garage Door?

A good weather seal system ensures optimal airtightness, preventing air and moisture infiltration, which helps reduce energy costs and improves the comfort of your garage.

Choosing the Right Weather Seal for Your Garage Door

Perimeter weather seals for garage doors typically consist of PVC blades and a rubber gasket at the bottom of the door. Garex also offers hybrid weather seals, combining PVC and aluminum, which provide better resistance to sunlight and increased durability.

Steps for a Successful Installation

Follow these steps for a successful installation:

  • Preparation: Ensure the garage door is clean before installation. Remove any old weather seals if necessary.
  • Measurement and Cutting: Measure the area to be covered and cut the new weather seal accordingly. Precision is crucial for effective sealing.
  • Installation: Start by installing the top seal, then proceed with the side seals. Ensure that the weather seals don’t interfere with the door’s ability to close properly.
  • Finishing Touches: For lighter-colored seals, space the screws evenly. For darker colors, Garex recommends one screw per hole.

Maintaining Weather Seals

Regular maintenance is essential to keep the weather seals effective. Clean them with mild soap and apply a silicone-based lubricant every 3 months.

Replacing Weather Seals

If you notice air infiltration despite regular maintenance, it may be time to replace your weather seals. Garex provides simple instructions to guide you through this process.

Conclusion

A proper weather seal system for your garage door is key to making your home more energy-efficient. Follow these tips to ensure proper installation and maintenance.
