SYNLawn’s exclusive HeatBlock technology is scientifically proven to lower rising temperatures by reflecting sunlight, thus reducing heat build-up and thermal emissivity. Heat build-up most often occurs when thermal energy from the sun’s rays hit the surface of an object. Emissivity is the scientific term for the degree to which a specific material emits heat. Just as dark clothing absorbs more heat than light clothing, artificial grass can also hold in and emit heat, which can make it uncomfortable when summer hits and temperatures rise. This is why SYNLawn, with HeatBlock technology, incorporates infrared reflective pigments that help to dissipate heat build-up, reducing fiber emissivity by as much as 20% cooler when compared to similar synthetic turf products.
