Roof coatings are a great benefit to commercial and residential roofing systems. They help your roof last longer by making them more durable, weather-resistant, and waterproof.
Behind elements like rain and wind, the sun is one of the leading destroyers of roofing systems. Prolonged sun exposure can lead to your roofing materials cracking, curling, and tearing.
During the summer, your energy bills increase due to increased air conditioning usage as a result of the rising temperatures outside. But what if we told you that there’s a way that you can protect your roof from the sun’s harmful UV rays as well as keep the temperatures inside your home moderate and cool.
An “ultra-white” paint capable of reflecting 98% of the sun’s rays has been developed by scientists at the University of Purdue in Indiana. The paint only absorbs 1.9% of the sun’s warmth, thus keeping your home cooler for longer. Previously developed “cool roof” coatings only reflected about 80% – 90% of the sun’s rays, making the “ultra-white” paint a major advancement in eco-friendly paint technology.
The “ultra white” paint development was part of a six-year project, lead by Xiulin Ruan, a mechanical engineer at the University of Purdue.
The paint consists of acrylic paint and barium sulfate. The barium sulfate particles assist in scattering the sun’s rays, thus reducing the amount of heat absorbed by the painted object. Ruan and his team believe that this paint can replace air conditioning systems in the future.
“If you were to use this paint to cover a roof area of about 1,000 square feet, we estimate that you could get a cooling power of 10 kilowatts,” said Ruan. “That’s more powerful than the central air conditioners used by most houses.”
The development of the paint marks a significant step in combating global warming. If used on an industrial scale, it could drastically reduce energy spent on air conditioning systems worldwide. The new coating can be applied to more than just roofs; homeowners can add it to their walls, decks, flooring, and more.
The study was published in the ACS Applied Materials and Interfaces journal.
