COOLWALL’s ceramic microspheres reflect infrared solar energy away from the wall surface before it conducts through the concrete block structure and into the interior. Standard exterior paint absorbs that energy and transfers it directly through the wall, raising the temperature of the rooms on the opposite side. Independent testing confirmed that COOLWALL-coated surfaces can run significantly cooler than surfaces coated with conventional paint of the same color. For a Coconut Creek home running air conditioning eight to ten months per year, that surface temperature reduction translates directly into lower cooling demand and reduced electric bills.
The savings are most pronounced on west-facing and south-facing walls, which receive the most sustained solar exposure during peak cooling hours. Haven’s estimators note the orientation of the home during every site visit and can identify which walls contribute the most to the cooling load. Coconut Creek homeowners who have made the switch to COOLWALL consistently describe a noticeable difference in how warm sun-facing rooms feel during the afternoon, particularly in spaces directly behind long stretches of exterior wall.
