In a matter of years, residential and commercial roofs may be coated in the whitest paint ever to reduce or possibly eliminate the need for air conditioning.
The paint, developed by researchers at Purdue University in Indiana, was certified by the Guinness World Records as the whitest paint in April. The paint reflects 98.1% of solar radiation at the same time as emitting infrared heat. This is an improvement on Purdue’s previous iteration that was 95.5% reflective.
