Paving the Way for a Cooler Tomorrow

At CoolSeal, we are committed to promoting sustainable practices and programs to help municipalities, private sector institutions and construction professionals create a more resilient infrastructure, positively impacting the health and wellbeing of their current and future residents.

Energy Savings

CoolSeal lower surface temperatures, mitigating the urban heat island effect. This contributes to cooler urban areas, which can improve comfort and reduce the need for air conditioning, leading to energy savings.​

Improved Quality of Life

The reduced surface and air temperatures make outdoor spaces more comfortable and safer for pedestrians and pets, encouraging outdoor activities and potentially contributing to healthier lifestyles

Preservation of Resources

By reflecting sunlight, CoolSeal prevents asphalts from absorbing too much heat, which can cause degradation over time. This extended lifespan means fewer resources  needed for repairs and replacements, conserving materials and reducing the demand for new resources

Reflect, Protect and Preserve

How It Works

Reflective Formula

Coolseal's unique formula, which is made with recycled materials and free of harmful chemicals, is designed to convert solar heat / harmful UV rays into other forms of light, interrupting  heat absorption.

Temperature Reduction

This reflection of sunlight directly reduces the surface temperature of the pavement, often by 10-20 degrees Fahrenheit under certain conditions, making it cooler to the touch and the surrounding area more comfortable.

Urban Heat Island Mitigation

By lowering pavement temperatures, CoolSeal contributes to reducing the urban heat island effect, which is the temperature disparity between urban areas and their rural surroundings.
CoolSeal leverages eco-friendly materials to cut waste and toxic emissions, enhancing community life by cooling the pavements, which extends their life, reduces upkeep costs, and fosters more sustainable urban infrastructure.

Find answers to commonly asked questions about CoolSeal's innovative asphalt sealcoat.

How do urban heat islands affect the environment?

Urban heat islands lead to higher energy usage and greenhouse gas emissions as people and businesses increase their use of air conditioning and fans. Without carbon dioxide-absorbing vegetation, more emissions enter the atmosphere.

What are sustainability benefits of mitigating urban heat islands?

Reducing surface temperatures and mean radiant temperature can lead to less energy use in the summer. Planting more trees and increasing vegetation cover, green spaces, and rooftop gardens helps absorb carbon dioxide, as well as protect against erosion and reduce stormwater runoff. Using surface materials like CoolSeal, which incorporates recycled materials in its formula and is free of polymers, hazardous volatiles, and carcinogenic additives, provides additional environmental benefits.

How effective is CoolSeal in reducing heat in urban areas?

CoolSeal reflects 30% more sunlight and lowers surface temperatures by 10-16℉, compared to uncoated asphalt. It can lower surface temperatures by up to 20℉ as compared to black-coat asphalt. It also lowers subsurface temperatures by nearly 5℉, resulting in long-lasting surfaces that reduce maintenance needs and save on costs.

Is CoolSeal considered a green product?

CoolSeal by GuardTop® is a fully green alternative to conventional sealcoats, which contain polymers and contribute to urban heat islands. CoolSeal is water-based and formulated with recycled materials, free of harmful chemicals.

How does CoolSeal contribute to environmental sustainability?

CoolSeal is manufactured with recycled materials and doesn’t use fossil fuels like tar coal or bitumen. It’s been proven to lower surface temperatures by an average of 12 degrees Fahrenheit during peak afternoon heat, as compared to traditional products. This cooling effect not only creates more comfortable environments, it can help decrease energy demand, which is associated with lower associated air pollution and greenhouse gas emissions. Additionally, when applied correctly, CoolSeal lasts twice as long as conventional sealcoats and increases the longevity of asphalt, thus reducing the cycle of asphalt replacement and waste.

What else do GuardTop and CoolSeal do to push forward sustainability?

CoolSeal engages in education and outreach on the issue of urban heat islands, as well as collaborates with forward-thinking institutions like the U.S. Green Building Council.
