We tested a shipping container in the Tucson desert, painting only the roof. The result was that the roof in direct sunlight was cooler than the side in shade, and the interior of the container was also cooler.
Image shows a sedan roof painted with CryoPaint. The thermal image demonstrates a significant reduction in surface temperature on the treated section of the vehicle, achieving sub-ambient temperatures.
Image depicts a control box on a 115°F day. The CryoPaint housing maintains a surface temperature approximately 15°F below air temperature, keeping internal components cool. The photo shows the box on a table, with grass in the background.
Image shows an early test using two mini car hoods. One was painted with CryoPaint, and the other with standard white automotive paint. This is the thermal comparison.
Image shows our hard hat prototype. We were able to demonstrate significant cooling on both the interior and exterior. *Painting a hard hat does not hurt the shell, but primer choice matters. See the hard hat FAQ for chemical compatibility and safety notes before applying.
Image shows our "space helmet" test using the Microclimate Air 3 positive pressure respirator. We painted the top portion of the helmet with CryoPaint and captured thermal images, which demonstrated significant temperature reductions on both the interior and exterior of the respirator.

"Painted the car roof - desert region, Cathedral City, CA."
Brian took CryoPaint to one of the hottest spots a car has - the roof - and put it to work in the full Cathedral City sun. One quart of CryoPaint, applied to the roof, earned a five-out-of-five verdict.
"The difference is amazing, you can clearly see the outline of what we painted."
Claire's 1920s Altadena house has almost no insulation. The back den was converted from a covered porch and, in her words, is "literally some wood with tar sheets on top." She had already tried a white cooling paint and reflective aluminum netting for shade, and the best she could get was a ceiling running 5°F to 10°F above outdoor air temperature with the air conditioning going full blast. She bought a quart of CryoPaint, coated a 5.5 foot square of the roof, then pointed a thermal camera at the ceiling from inside the house. The painted section reads 86.3°F while the untreated ceiling beside it climbs past 100°F in the same frame. She ordered a 5 gallon pail the same day to do the entire back section. As she put it, it is "a whole lot cheaper than replacing the roof."
"I had my doubts - but it worked as you promised. I got permanent voltage from my TEG, enough to keep a red LED blinking day and night. No battery needed."
Yauheni, an energy-harvesting enthusiast in Mannheim, Germany, set out to answer a question most people only theorize about: can radiative cooling alone make electricity? He coated his homemade thermoelectric-generator (TEG) panel with CryoPaint, pointed it at the open sky, and let the temperature difference between the cooled surface and the surrounding air do the work. Over two clear days and nights he measured continuous output - roughly 0.1 mW from a small 0.125 m² panel - enough to keep a red LED blinking around the clock with no battery, just long-life ceramic capacitors. His takeaway: radiative cooling can generate power "anywhere you have access to the sky, day or night."
A ranch owner documented their full experience applying and testing CryoPaint on their property. The long-form video covers application, real-world conditions, and thermal results.
A customer in Texas applied CryoPaint to the top of a shipping container and was amazed by how cool the surface became - literally speechless at the result.
The Action Lab demonstrates how CryoPaint can drive a Stirling engine purely from the temperature difference between a radiatively cooled surface and the air temp.

"Learned about Cryo X from a big influencer on Youtube. I INSTANTLY ordered it. Of course Cryo ended up SWAMPED due to the size of the influencer and I had to wait an extra week. But the company was cordial and did all they could to soften the blow of waiting. It was worth the wait!!! I have a 20x16 tin roof covering a fish tank and wanted to slow down the heating due to radiation. I painted a 10x10 patch of the tin directly over the fish tank. The next day, I noticed that you could TOUCH the tin in the middle of the day and i was only warm. When I moved to the unpainted tin it would burn your fingers. VERY GOOD. I believe my fish tank warming has slowed. I'm fairly sure there are TWO forms of heating prevented/slowed down: 1) The radiation that you "feel" regardless of ambient temperature - that is remarkably less and 2) the radiated heat (not radiation though) of the HOT tin panel radiating *AND* heating the ambient temperature below the tin. It really has turned our fish tank area into a wonderful cool area to sit and enjoy. We sit and feed our blue cats all the time! I love the product and will finish the roof soon. My next project will be painting my outdoor "ranch jackery-ish" solar systems for telementry."
"This stuff is really amazing. I don’t understand how it actually feels cooler to the touch than the surrounding temps. Science. I will definitely be applying this to other projects soon. The auto test seems to be holding up well this season and the dune buggy and trailer and RV are all being considered. Great potentially energy saving product in this desert environment. I’m getting very curious as to what it can do for the airconditioning energy use. Probably do at least partial trailer next Spring and can begin comparing summer savings."
"I tested the paint on a ceramic tile. The effect is astonishing. The surface temperature stayed close to the ambiet temperature and 15-20°C below the reference temperature of an unpainted ceramic tile (clear sky). In the teststand the backside of the ceramic tile is isolated with 6cm PIR-insulation. The backside temperature of the tile was measured with PT1000 sensors and a putty with high heat transfer."
"Stunning results. CryoX advertises 15 degrees. I saw over 30 and have youtube videos that show it. Even more of a delta after 2nd coat. Crazy results, 30 degrees. I just did a 3x3 with the small bottle. A gallon is en route right now and I am excited to see what it does to the inside of the RV with those results on the roof."
"This stuff is impressive. Works. My gate controller box (black) was cooking my lithium battery, up to 140F in summer. CryoPaint dropped it 20 degrees in direct sun. This should give me quite a bit longer battery life. Wow."
"This paint Works! I have a friend with beehives, and he is painting them with CryoPaint to keep the cool in the summer."
Reviews are customers describing results on their own surfaces, not controlled tests. CryoPaint's published performance is up to 15°F below the air temperature, and real results vary with climate, sky view, surface, and how much paint goes down. These are a selection of the reviews left on cryox.us, shown in full and unedited.
RMI (Rocky Mountain Institute) is one of the leading organizations researching and deploying radiative cooling in the real world. Cryo X Co applied to and was accepted into two separate RMI pilot programs.
"We are excited to inform you that Cryo X Co has been selected to participate in our United States study. Our application pool was very strong, and your product displays the blend of performance, scalability, and cost we sought for this study."
