What is Radiant Barrier Paint? 

Radiant barrier paint is often referred to as liquid foil. Most of them are made by grinding aluminum into a very fine powder, then mixed in with clear paint. When applied to any surface, the clear paint eventually dries up, leaving a layer of aluminum from the powder added to the mix. 

The primary purpose of radiant barrier paint is to reduce the amount of radiant heat absorbed into the attic, which helps keep the home cool and well-insulated during the hot summer months—a drop in temperature at night is a given here.

Radiant barrier paint can also be applied to garage doors and roofs. This paint will not damage or wear down your roof shingles either.

Most homeowners even have the barrier paint applied onto the sidewalls. This application has helped them prevent condensation and moisture buildup inside their walls.

Moreover, barrier paint is an investment in itself as it lasts an average of 10 years!

If you are looking for a cost-efficient method to reduce your utility bills and keep your home at the desired temperatures during summer, then installing or spraying on the radiant barrier paint can help.

Moreover, you can also purchase radiant barrier paint online. However, make sure the service provider is certified and reliable. You can even hire them for the application process.

How to Ensure Your Radiant Barrier Paint is Effective 

Radiant barrier paints can be a bit tricky to get right because they require a set of measures to be followed strictly during application.

Here are some of the things you should keep in mind when using these paints. By following and being wary of these guidelines, you can expect your radiant barrier paint to provide optimal results. 

  • The correct coverage is a must. Applying a layer that is too thick or too thin can make the radiant barrier paint useless. For this, it’s best to skip the DIY project and hire a professional contractor or service provider. 
  • Opt for a radiant barrier paint that is of premium quality. It might be slightly more expensive, but the long-term return on investment will be higher. Thus, making up for the initial first investment of purchase and application. Check for the factory seal or label on the radiant barrier paint. You want to make sure that the product you have purchased is authentic. 
  • Ask your commercial contractor or service provider to apply a layer of primer before applying the radiant barrier paint. The cost for this is usually separate from the application of the paint. However, this additional step is sure to bind the radiant paint barrier on the surface better, making it last for a long while. 
  • Application of the radiant barrier paint requires wearing personal protective equipment and the use of specific tools. If the paint is being sprayed onto your roof, the correct spray tip and pressure are needed. Only an experienced contractor can get this right.
  • Ensure the paint has enough air space and is not sandwiched between two layers. Insufficient airflow will reduce the primary benefit of the barrier paint.
  • Avoid having water mixed into the paint to “cut” it. Most inexperienced contractors add water to radiant barrier paint to extend coverage. Be mindful of this when having it applied.
  • Inquire about whether the radiant paint is perforated or non-perforated. The former type allows water vapor and air to pass through as it is porous. The non-perforated style does not have this property.
    Applying it in your attic will thus only lead to moisture buildup and make it damp and prone to a mold outbreak, especially if you live in a humid area.

The Bottom Line  

Radiant barrier paints are pretty effective for keeping your home cool throughout the hotter months. However, they work great for hot and warm climates and are known to bring down your energy costs.

Radiant barrier paint is one of the ideal ways to save on unwanted expenses and help save the planet. So, get your hands on the most premium brand of radiant barrier paint from your nearest contractor or home renovations expert. 

Well, what are you waiting for? Get started today and apply the paint to your roof, attic, or walls. You will be glad you made this investment in the long run, that’s for sure!
