Reflective Roofs on Shipping Containers & Trucks
March 14, 2022

Shipping containers are commonly painted blue, red, green, or other various monochrome colors on all sides. While this might make containers more distinguishable, these choices of paint lead to significant heat absorption, some of which is then conducted to the atmosphere. There is a simple solution to this problem. By painting the roofs of containers and truck trailers white, the object reflects more solar energy toward space and heats up less. This could also reduce the urban heat island effect around ports and other industrial facilities where shipping containers are common. Solar reflective paints have already been developed for other applications and are readily available commercially.  There is no extra cost to paid the roofs white rather than another color.
