Synthetic Turf Field temperatures Compatible with Natural Grass

Published 07-30-12


Recently completed outdoor testing at the ISA Sport USA Lab in Lubbock, TX further substantiates the fact that Limonta Sport synthetic turf with organic InfillPro Geo© greatly reduces the surface temperature of the synthetic playing field to the point where it is compatible to playing on natural grass.

This latest temperature comparison testing was deliberately staged outdoors in some of the most extreme high temperatures and arid atmosphere available in the South West, measured with and without water, to more accurately simulate real world conditions for practical sports field evaluations.  The four test bed samples included natural grass, synthetic turf with organic InfillPro Geo©, synthetic turf with rubber only and synthetic turf with rubber/sand combined.  In every instance, the organic InfillPro Geo© filled turf was well within 20°F of the natural grass sample as compared to the  combined rubber/sand filled turf that measured as much as 76°F hotter than the natural grass. 

Prolonged retention of moisture

An average of 12 ounces of water per square foot was applied to each of the four test samples to achieve a uniform 5% moisture content. After little more than an hour in the hot sun, it was clear that neither of the samples containing rubber was able to maintain moisture while the sample with organic InfillPro Geo© was still reading 4.5% on the moisture meter.  It was also noted that with sustained 20 - 30% relative humidity, the organic infill still maintained up to 2% moisture even after three days with no added water.  This absorptive/retentive characteristic is due to the porosity of the natural cork and stabilized with the ideal blend of coconut fibers (coir).  InfillPro Geo© by Limonta Sport is world patented for the use of cork and coir as an infill for synthetic turf.  In the USA, this natural blend is sometimes referred to as “corkonut”.

Tester’s summary

Rusty Abell, a principal of ISA Sport USA who conducted the tests, stated in his report:

“This product performs very well compared to every other product on the market today. When all moisture content and amounts are comprehended by the field technician, this product would take the massive heat issue completely away from the all-weather turf field installation.   As you will notice on the reports, once the moisture level knowledge was obtained, it would be no problem to keep the athletic field within 10% on average of the ambient temperature, and this accounts for full sun and wind”.
