Saving Utility Costs with Exterior Coatings: COOLWALL®

It’s a fact of life that homeowners will periodically have to upgrade the exterior coatings of their homes. Painting helps preserve the integrity of the home and offers both aesthetic and protection benefits.

Recent technology advances give homeowners more options than ever before. Instead of traditional exterior paint, homeowners may now choose energy-efficient exterior coatings that help to save money on utility costs. One of the most popular and effective products is COOLWALL® by TEX•COTE™. This coating reflects the heat of the sun, reducing costs associated with heating and cooling the interior of the home. Let’s explore how COOLWALL® exterior coatings work and how they can save you money.


COOLWALL® was developed by a team of chemists and engineers at TEX•COTE™. The company borrowed technology already in use by the U.S. military to reduce the “heat signature” of its vehicles. The heat signature refers to the amount of heat absorbed by the sun; untreated vehicles subjected to solar energy are more visible to thermal imaging equipment.

COOLWALL® uses an infrared-redirecting technology called Kynar®. The coating system reflects solar heat by changing the invisible part of the light spectrum (infrared rays). This can be accomplished without changing the color of the coating, which is why COOLWALL® comes in 570 color choices (far more than competitors’ exterior coating systems).

After application of the coating, homeowners can save over 20% on cooling costs. In several laboratory tests, COOLWALL® was shown to lower exterior wall surface temperatures by as much as 40 degrees as compared to untreated surfaces. Reducing the amount of thermal energy absorbed by exterior walls means that the heating and cooling system doesn’t have to work as hard. This, in turn, saves homeowners money on utility bills. And, because heating and cooling systems are so expensive, reducing the amount of work they do helps them to last longer. By using less electricity, homeowners also reduce harmful greenhouse gas emissions.

PACE Financing and COOLWALL® Coatings

In states with Property Assessed Clean Energy (PACE) financing, homeowners can take advantage of attractive financing options to help pay for energy-efficient home upgrades. In California, heat-reflective exterior coatings like COOLWALL® are covered by PACE financing. Homeowners can have these coatings applied to their homes’ exteriors by qualified home improvement contractors with no out-of-pocket costs, and the repayment occurs with the annual property taxes over a period of time (usually five to ten years).

By applying an advanced exterior coating like COOLWALL® to the exterior of a home, homeowners can save money while improving the appearance of their homes. It’s a win-win!
