COOLWALL’s infrared-reflective pigments redirect solar heat energy away from the wall surface before it transfers through the concrete block and into the interior. On a Fort Lauderdale home with significant west-facing or south-facing wall area, the surface temperature reduction can be substantial. Independent testing at the U.S. Department of Energy’s Oak Ridge National Laboratory documented meaningful surface temperature differences between COOLWALL-coated surfaces and conventionally painted surfaces of the same color. Lower surface temperature translates directly to reduced cooling demand inside the home.
The savings accumulate over time because Fort Lauderdale’s cooling season is effectively year-round. A reduction in the heat conducted through the walls during peak afternoon hours means the air conditioning system cycles less frequently, which reduces both the electric bill and the mechanical wear on the equipment. Haven’s estimators note the sun exposure of each wall face during the site visit and can identify which surfaces will benefit most from the thermal rejection properties of the COOLWALL coating.
