Can You Use Thermal Barrier Coatings on Garage Doors ?


If you are looking for a way to improve the insulation and longevity of your garage door, applying a thermal barrier coating is one of the best ways to achieve those goals. In this article, we’ll explore the main benefits thermal barrier coatings provide for garage doors and cover a few other vital topics related to these incredible coatings. 

How Thermal Barrier Coatings Improve Garage Doors 

Thermal barrier coatings can improve the performance of a garage door in several impactful ways. Below are a few of the leading advantages you can expect when you apply a thermal barrier coating to your garage door’s surface:

  1. Improved insulation: One of the greatest benefits of thermal barrier coatings is that they reduce thermal energy transfer. In simpler terms, this means that these coatings provide an incredible enhancement to your garage door’s insulation. After applying thermal barrier coatings, the inside of your garage will maintain a more stable temperature and be less affected by extreme temperature changes outside. 
  2. Reduced corrosion: Thermal barrier coatings provide a strong layer of protection for many materials, including metals. Garage doors often include metal components, which are susceptible to corrosion when exposed to moisture. The protection a thermal barrier coating provides shields materials from moisture and makes corrosion far less likely. 
  3. Less condensation: While it may seem benign, excessive condensation can lead to several issues, including mechanical inefficiencies, mold and mildew growths, and more. Fortunately, the best thermal barrier coatings discourage condensation and the subsequent issues it can cause. 
  4. Energy savings: Thermal barrier coatings protect the interior of your garage from extreme temperature changes. By maintaining a more consistent temperature, these coatings also make it easier for your HVAC units to operate. This ease of operation leads to less energy use and lower energy bills in the long run. 
  5. Longer lifespan: The final major benefit of thermal barrier coatings for garage doors is increased longevity. Since these coatings provide an immense amount of protection, you can expect garage doors that have thermal barrier coatings to last longer and require fewer repairs than those that don’t.

How to Apply a Thermal Barrier Coating to a Garage Door

Now that you know there are several benefits to applying a thermal barrier coating to your garage door, it’s time to learn more about the application process. The good news is applying a thermal barrier coating to your garage door is easier than you might expect. Here are some of the primary steps involved in this process:

  • Clean the garage door surface: Removing dirt and debris from your garage door allows for better adhesion when applying a thermal barrier coating.
  • Ensure the correct humidity and temperature: Thermal barrier coating applications are most successful when specific environmental factors are in place. Mainly, you’ll want to ensure that the application area has moderate or low levels of relative humidity. It is also helpful to apply thermal barrier coatings where the temperature is at least 55 degrees Fahrenheit. 
  • Apply the coating with a sprayer: The best way to achieve an even application of thermal barrier coating is by using a sprayer. While it’s possible to use a brush or roller at this stage, doing so can cause your thermal barrier coating to be uneven and less effective. Before applying the coating, check its specifications to ensure you’re using the ideal type of sprayer for your thermal barrier coating. 

How Long Do Thermal Barrier Coatings Last

By now, it’s clear that thermal barrier coatings are beneficial to garage doors and that they are relatively easy to apply. However, you’re likely wondering how long these coatings will last. The answer to that question depends on the location in which you apply the coating. 

For example, thermal barrier coatings in indoor settings can have a nearly indefinite lifespan. Since indoor coatings don’t need to withstand the harsh elements of the outdoors, they often never require repairs or replacements. 

By contrast, outdoor thermal barrier coatings, such as those applied to a garage door, are not nearly as long-lasting. Still, you can expect these thermal barrier coatings to last for about 10 to 15 years before they require repairs or replacement.
