Everything You Need to Know About TºCool® Infill: FAQs and Benefits
Synthetic turf has revolutionized how we approach landscaping, sports fields, and play areas. But one of the biggest concerns continues to be surface temperature—artificial grass can become dangerously hot. That’s where TºCool® Infill makes a real difference.
TºCool® is a patented evaporative cooling infill that significantly reduces surface temperatures by storing and releasing moisture through natural processes. In this blog, we’ll walk you through the most frequently asked questions about TºCool® to help you understand why it's the go-to solution for cooler, safer, and more sustainable turf systems.
How Much TºCool® Infill Is Needed Per Square Foot?
The effectiveness of a TºCool Infused synthetic turf System depends on proper application. With today’s wide variety of turf products—each with different pile heights and face weights—the quantity of TºCool sand infill should be calibrated to the specific turf profile.
That’s why we developed the TºCool Infill Calculator.
Whether you’re a contractor, facility manager, homeowner, or installer, precision matters. Over- or under-application can compromise cooling effectiveness and long-term turf performance.
Access the calculator to calculate the exact poundage you need for your project. This ensures consistent cooling across the entire turf system and provides the right moisture retention levels to fuel the evaporative process.
Formula Explanation:
Formula: (Pile Height - Infill Reveal) ÷ 1/4" = Pounds per square foot.
Footnotes:
- *1 lb of TºCool sand per sq ft fills 1/4" depth.
- We recommend a minimum of 2.5 lbs of TºCool Infill per square foot to achieve sustained cooling efficacy.
- The specific climate in your area can require different levels of hydration.
- Turf Pile Height = The length of the synthetic turf blades from base to tip.
- Infill Reveal = The visible portion of infill above the thatch.
What is the lifespan of TºCool?
One of the many benefits of TºCool® is its longevity. With proper installation and regular maintenance, your TºCool® infill will provide years of effective cooling.
However, like all turf systems, infill can migrate over time—especially in high-traffic zones or areas subject to heavy rainfall or wind. In those cases, top-offs are easy and affordable. Just refill the surface to the original specification and you’ll restore both cooling performance and comfort underfoot.
After Hydration, How Long Does TºCool® Cooling Last?
This is one of the most common questions we hear, and the answer depends largely on your local climate, humidity levels, and watering schedule.
On average, you can expect up to 4 days of cooling after hydration—whether that comes from rain, irrigation, or humidity. In humid regions or shaded applications, the effect can last even longer.
In hotter, arid environments like the Southwest, it may be necessary to irrigate every 1–2 days to keep the system optimally hydrated. But no matter the climate, the science remains the same: as the sun heats the turf, stored moisture is slowly released from the TºCool® infill, creating a natural evaporative cooling process.
How Much Water Is Needed to Activate and Maintain TºCool®’s Cooling Power?
TºCool® was engineered to be efficient and sustainable when it comes to water use.
Each square foot of turf with TºCool® Infill can hold approximately:
0.36 gallons of water
1,359 grams of moisture-retaining content
Because of this capacity, only minimal irrigation is required to activate and maintain the cooling process. Most of the water needed can come from natural sources—like rain and ambient humidity. However, during periods of drought or in low-humidity climates, you can manually apply water via sprinkler or hose, or use an automatic irrigation system for convenience.
Remember, as 1 gram of water evaporates, it removes 450 calories of heat energy from the turf surface. That’s powerful, passive cooling at work—every day.
Is TºCool® Environmentally Friendly?
Absolutely. TºCool® was designed with the health of people, pets, and the planet in mind.
Here’s why it stands out:
Non-toxic and non-hazardous: Safe for children, pets, and athletes.
Free from heavy metals and VOCs: No harmful off-gassing or pollutants.
TºCool Sand is not a microplastic: TºCool®’s chosen Sand is a natural mineral product, and our patented, proprietary coating is not a synthetic polymer or acrylic / vinyl base coating.
Our antimicrobial derives from a renewable resource: Helps suppress bacterial growth and odors without the use of harsh chemicals or heavy metals.
Saves water long-term: Because TºCool holds onto moisture, it reduces the need for frequent watering compared to turf without a cooling infill.
Additionally, using TºCool® helps reduce the urban heat island effect, making it a climate-smart choice for schools, municipalities, and homeowners looking to do their part for sustainability.
Where Is TºCool® Best Used?
TºCool® is versatile and ideal for any synthetic turf application, including:
Residential lawns and landscaping
Playgrounds and daycares
School and university campuses
Dog parks and pet runs
Sports fields (soccer, football, baseball, etc.)
Rooftop or urban installations
Whether you're protecting a child’s feet at recess, an athlete’s performance on the field, or a pet’s paws in summer heat, TºCool® enhances comfort and safety wherever synthetic turf is used
Why Not Just Use Plain Silica Sand?
Most synthetic turf systems use common silica sand—an inexpensive option, but one that comes with some serious performance trade-offs. Most silica sand is sub-angular, meaning its particles have sharp edges that lock together, leading to compaction over time. This not only reduces drainage and impacts playability, but it also makes the surface harder and more abrasive. It’s cheap, yes—but you get what you pay for.
Standard Slica Sand
TºCool® Infused Silica Sand
Enter TºCool®—a premium infill solution that goes far beyond the basics. TºCool is highly spherical and well-rounded, which means the particles move freely, allowing the system to stay loose, breathable, and better draining. Its shape also makes it non-abrasive, reducing wear on turf fibers and being gentler on skin and paws. Because it doesn’t compact like angular sand, you maintain a consistent, high-performance surface with less maintenance over time.
Traditional silica sand has minimal heat capacity and does not contribute to cooling the turf. While it may serve as basic ballast or support for the turf blades, it does nothing to address the extreme surface temperatures that synthetic grass can reach—often 30 to 60 degrees hotter than ambient air temperatures.
TºCool is also cleaner, more uniform, and features a natural tan color that blends beautifully with the turf—no more glaring white sand peeking through. In short, it’s not just functional—it’s really sexy looking stuff. The kind of infill that elevates your project from standard to standout. TºCool® combines the benefits of silica sand with patented evaporative cooling technology. In fact, it lowers turf temperatures by up to 50ºF, providing comfort and safety without compromising the look or feel of the turf system.
