Cooler Futures Ahead

Revolutionizing pavement maintenance with its solar-activated, high-performance sealcoat, CoolSeal is uniquely designed for socially responsible communities and institutions looking towards a cooler, healthier future.

The Smart Choice

Reflecting sunlight rather than absorbing it, CoolSeal significantly lowers surface temperatures, distinguishing itself from traditional asphalt that exacerbates urban heat. Lasting twice as long as conventional coatings, CoolSeal is the leading choice in high-performance smart surfaces.

Put to the Test

Proven to Outperform

Among many other city initiatives currently in progress, CoolSeal has most notably been put to the test by the City of Phoenix, Arizona, as part of their Cool Pavement Pilot Program and Los Angeles' Cool Streets LA. The results—CoolSeal is proving to be the best choice, and only fully-green choice, for cities seeking heat relief, energy savings and innovative, long-term solutions.

Cool Your Streets

Reflecting sunlight rather than absorbing it, CoolSeal significantly lowers surface and ambient temperatures, distinguishing itself from traditional asphalt that exacerbates urban heat.

02
Save Energy
Promote Efficiency

Choose Sustainable

CoolSeal contributes to lower energy consumption within urban buildings and lasts twice as long compared to traditional options. This translates into considerable energy and resource savings in addition to reduced greenhouse gas emissions, contributing to broader sustainability goals.

03
Improve Quality of Life
Enhance Health and Safety

Promote Happy

CoolSeal addresses the urban heat island effect, which has been shown to exacerbate health risks, particularly among vulnerable populations. Reduced surface temperatures mean less heat stress for individuals spending time outdoors, promoting a more active and outdoor lifestyle. Additionally, these advanced materials offer enhanced street traction for vehicles, minimizing the risk of accidents during wet conditions. Moreover, their reflective properties improve nighttime visibility, making streets safer for both drivers and pedestrians after dark.

More than asphalt protection

WEBINAR: Health Case for Climate Action — How Medical Experts Are Driving Change

The latest Cool Communities, Healthy People Webinar brought together leading voices from the medical community to address one of today’s most pressing challenges — extreme heat and its growing impact on health. Hosted by CoolSeal’s Maria Koetter, the session featured Dr. Lisa Patel, Shelley Mann-Lev, and Dr. Keisha Callins, who shared how health professionals are organizing, advocating, and educating to protect vulnerable populations from rising temperatures. Speakers highlighted the direct health risks of heat — including dehydration, heatstroke, and exacerbated chronic conditions — while underscoring the importance of local policy, education, and rapid response systems. Personal stories of loss and resilience reminded attendees that climate action is also a health imperative. CoolSeal, developed by GuardTop, continues to play a critical role in urban cooling with over 70 million square feet applied worldwide, supporting communities through reflective pavement technology that reduces surface temperatures and improves livability. The webinar reaffirmed that by combining innovation, health leadership, and community engagement, we can build a cooler, healthier, and more resilient future.
