Radiative cooling is happening everywhere, all the time. SkyCool lets you control it.
Frost can form at night even when the air isn't freezing. The water is cooled by the ambient air, and cooled even more by radiating heat to space.

By reflecting nearly all the heat from the sun, and radiating more heat to space, SkyCool stays cooler than that air around it 24 hours a day. That cooling effect can be harnessed to cool buildings and systems.
The most important feature of SkyCool Film is its incredible reflectivity. That is what prevents it from getting hot in the sun. SkyCool Film reflects nearly all of the visible and UV light that makes other outdoor objects, like roofs or people, hot.
The big difference between SkyCool and regular reflective materials, is that SkyCool is also a “selective emitter”. Meaning, while all objects emit infrared radiation (heat), SkyCool emits infrared strongly in a specific band (8-13 microns) that isn’t absorbed by the gasses that make up our atmosphere.
This means that SkyCool radiates more heat to space than other materials. That keeps SkyCool cooler than other materials.
In addition to reflectivity and emissivity, SkyCool, like all objects, loses heat through convection (the cooling effect of a moving air).
However, when it is especially hot outside, convection isn’t a strong or efficient way of cooling. That's why SkyCool is better than a fan: We still provide cooling through reflection and radiation even when the air is too hot for convection.

Our paper describing Passive Daytime Radiative Cooling has become among the most cited in the field of Physics.
Through ongoing R&D, we continue to push performance, drive down cost, and expand applicability of this breakthrough idea.

SkyCool Film is the basis of both SkyCool Roof and SkyCool Panels.
SkyCool Film is created by laminating specialized plastics carefully selected for their radiance and reflectivity when deployed in combination with each other.
SkyCool Film, SkyCool Roof, and SkyCool panels are manufactured in the United States.

SkyCool harnesses a natural phenomenon that was first used thousands of years ago to make ice at night in the desert. Using materials science and mechanical engineering in a lab at Stanford, we created radiative cooling products that work 24 hours a day, without electricity. Our discovery led to one of the most cited papers in Physics, and a killer TED Talk.
Refrigeration was invented in 1834. The world has been waiting a long time for a new way to cool off.

what this COULD mean
Remember when it was called "Global Warming"? So do we.
When a SkyCool installation removes heat from a building, it also removes it from the planet. It doesn't blow it into the outside air like most cooling systems.
There are many ways to combat climate change, and we need most of them if we are going to keep our planet stable. SkyCool stands out by addressing heat directly, rather than indirectly by reducing emissions of heat trapping gasses. The more SkyCool, the cooler the planet.
The SkyCool team comes to work everyday to serve our customers, and to help our customers save our planet.
