The Arlington Heights Park District made a conscience effort to select a new infill product called CoolPlay. CoolPlay, made by Field Turf, replaces the top layer of its crumb rubber/silica sand blend with an exclusive cork material. The cork layer lowers field temperatures by as much as 35 degrees versus the traditional sand/rubber systems. The cork layer is also an alternative addressing the crumb rubber concerns raised by the public about the safety of recycled tire crumb used in playing fields. Click here to learn more.
