With typical applications preventing local air temperature increases and lowering peak electricity demands, cool roof systems are growing in popularity

 

Cool Roofs are made of a material that upgrades the exhibition of the rooftop by reflecting daylight, along these lines decreasing energy utilization. It is involved a level or finished material surface, which is built up by an unbending layer. The intelligent surface of the Cool Roof is made of a metal foil with a covering of intelligent material. A Cool Roof is an exceptional structure development measure, which offers various ecological benefits. The Cool Roof is additionally utilized in the business area to stretch out capacity regions to roofs that are not exactly standard.

Cool Roofs are made of durable water-resistant materials such as slate, acrylic, concrete, stone, and tile. These roofing materials are non-combustible, thus offering protection against fire. It can also reduce heat gain and energy consumption during the summer months. Cool Roofs are constructed with a variety of distinctive designs, from basic straight-line styles to elaborate multi-colored roofing materials with retro-reflective shingles. The most common type of Cool Roof is the textured one, which is also known as roof coatings. These are made from polyurethane foam or epoxy coating and are designed to provide added protection against ultraviolet light, rain, snow, hurricanes, and other harsh weather conditions. They are cost-effective, even for commercial and industrial buildings. The coatings also prevent the growth of mold and mildew in cooler climates.

For homes and offices that have single-ply membrane roofs, such as on the south and west side, Cool Roofs may be used to create additional savings. Roof coatings reduce the temperatures by up to twenty-five degrees. Even in the hottest climates, the coatings can prevent the summers from being too hot and reduce unbearable summertime temperatures. The secondary cooling effect created by the coating is made up for by the insulation and stormwater run-off. This means that while installing the Cool Roof, the building's energy efficiency is increased. Recently, in May 2020, Nouryon launched elastomeric cool roof coatings solution Expancel, which reflects light.
