ChillSkyn Blog | Cooling by the Numbers: How Data Validates the Promise of Passive Radiative Technology
top of page
Passive Daytime Radiative Cooling is a phenomenon where a surface spontaneously cools by reflecting solar radiation back where it came from. Unlike HVAC systems, which have a net heating effect while also emitting hydrofluorocarbons, PDRC stands as an eco-friendly solution that will greatly reduce energy expenses and provide electricity-free cooling anywhere on the planet.
More than 80% of radiated energy escapes the earth's atmosphere within the infrared transparency window (8-13 μm).

PolyFrost™ Coating
PolyFrost™ is a revolutionary polymer coating formed via phase-inversion that exhibits both outstanding solar reflectivity and infrared emittance. This versatile coating cools surfaces an average of 6° C below ambient temperature during peak hours. It is intrinsically hydrophobic and UV resistant, applicable on various surfaces including metals, fabrics, plastics, and wood, and can also be made free-standing.
