Passive Daytime Radiative Cooling is a phenomenon where a surface spontaneously cools down by reflecting sunlight and radiating heat back into outer space. Unlike HVAC systems, which have a net heating effect while also emitting hydrofluorocarbons, PDRC stands as an inexpensive and eco-friendly cooling 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 via
the atmosphere's infrared transparency window (8-13 μm)
INTO OUTER SPACE!
Unparalleled 24/7 Cooling
Standard cool surfaces can only achieve subambient temperatures during night-time. In contrast, PDRC surfaces remain colder than ambient even at peak solar radiance
Peak summer day with 32° C
PolyFrost™ is a revolutionary polymer coating formed via phase-inversion that exhibits both outstanding solar reflectivity and infrared emittance. It is intrinsically hydrophobic and UV resistant as well as tremendously versatile, being applicable on various surfaces including metals, fabrics, plastics, wood, and can also be made free-standing.
Cools surfaces an average of 6° C below ambient temperature during peak hours
