Phoenix CoolSeal Neighborhood Streets

The City of Phoenix began its cool pavement pilot program using CoolSeal by Guardtop on August 10, 2020. Through various studies conducted by the EPA and universities, it has been proven that cool pavement is instrumental in the cooling of ambient and surface temperatures as well as reducing the effects of Urban Heat Islands, which the city suffers from. CoolSeal has been applied in various U.S. cities and other countries including Australia. The city of Los Angeles first applied the product in 2015 and the City of Phoenix has been carefully following and studying its effectiveness. CoolSeal has been shown to decrease asphalt surface temperatures by up to 40 degrees F and lower ambient temperatures by up to 6 degrees F. City officials are hopeful they will be able to cool Phoenix down during its warmer months. To learn more about CoolSeal please visit
