Is Tan Envirofill Cooler than Green Envirofill?

Some decisions are harder than others…

Crunchy or Smooth peanut butter?
Grape or Strawberry jelly?
White or wheat bread?
Chicken or Steak?
Ford or Chevy?
Natural or Synthetic Turf?
Green or Tan Envirofill?

There is actually not as big of a difference as one might think. In fact, this comparison has been tested many times before and the difference is usually only a few degrees. Those few degrees would be indistinguishable to someone on the field so in the end it’s a matter of aesthetics and if it were up to us, we would go green.

 

Surface Temperature & Infill - USGreentech Envirofill The above test was conducted using the same turf in three different systems with the same amount of fiber reveal. And the results show that the difference between tan and green is statistically insignificant.

 

Even though tan has a pigment which makes it more tan than the natural, yellow sand, it still looks like sand to the untrained eye. Going green signifies that you’ve got the real deal, something different, something unique.

When comparing the heat from a synthetic turf system with crumb rubber to one with Envirofill (regardless of color), one can see a measurable improvement in the surface temperature. Now, we’ll point out that it’s still warm. We won’t deny that. It's what we refer to as “less hot” than rubber. If you’re looking for something appreciably cooler, we recommend checking out our natural infill, Safeshell, which uses evaporative cooling to reduce surface temperature.

Let’s talk technical. Lighter colors equal more reflectivity, right? Well that’s not always the case. The measure of a product’s ability to reflect the part of the light spectrum responsible for heat is called the Total Solar Reflectance or TSR. The TSR is the percentage of total solar energy that is reflected away from the surface. In the case of tan versus green, their respective TSR scores are 26% for Envirofill green and 39% for Envirofill tan. As a comparison, crumb rubber’s TSR score is 10.6%. These scores are for the products by themselves and there is not necessarily a direct correlation to how they will perform in the synthetic turf system. There are a lot of variables… infill is not a flat surface so the solar radiation will not necessarily bounce directly back. The turf blades also play a big role in trapping and absorbing the solar radiation.

Let’s talk practical. 95% of our customers select green because it blends in better. While the flyout is drastically reduced over crumb rubber systems, what does fly out is practically unrecognizable because the green color blends into the turf. Out of sight, out of mind! With an Envirofill field, gone are those days when rooster tails of rubber would fly up from athlete’s feet. Tan is bland. Go bold, go green!
