An object doesn’t have to be white to be cool… Two objects can be identical in visible colour, yet their infrared reflectance characteristics can be completely different. The object that reflects infrared light will remain cooler than the object that absorbs it. Because IR-light comprises fully half of sunlight, the IR-reflectivity of an object is even more important than its colour when it comes to heat build-up.

The IR heat signature was captured by an infrared camera from the rear of two panels during a Solar Radiation Exposure Test. Astec Energy Star^® Low Sheen was one panel and the other, a competitors premium exterior acrylic.

Both panels were identical in colour.
