Many houses in Switzerland are being painted white against heat

White lime houses are usually used to seeing in Mediterranean countries because of the great heat.

White houses are a practical solution to lowering the temperature inside buildings by 5 degrees.

White - limeed houses are a practical trick to lower home temperature by about five degrees. It is the cold roof, a technique widely used in the United States to combat heat waves and that is also slowly developing in Switzerland; a procedure that essentially includes the already known Mediterranean habit of whiteing houses against the typical heat of low latitudes.

The basic idea is simple: White reflects the sun's rays better. By doing so, roofs help to keep the lower layers of the colder atmosphere and to combat the phenomenon of heat islands in urban centers. It's a simple operation but with an extraordinary result. “At the sunset measured 60 degrees on the surface of the roof asphalt with a laser thermometer and slightly less than 30 degrees in the first layer of thermal ink applied right next to it”, explains Robin Liengme, director of a company in Geneva, for RTS microphones.

A change that is recorded within the walls of the house. After applying the ink, the interior is cooled on average <x0m 4 and 6 degrees at an external temperature of 25 ʹ30 large, and with 8 degrees 12 degrees by 30 degrees out of”.

A particular compound characterizes the dye made from the ceramic microsphera, or remains of the shell of the oysters. Currently, with the strong development sector, its price fluctuates between 45 and 60 cents per square metre and can be applied to many surfaces, such as the bitumenous roof, lymerine, and tiles. /Okinfo. ch
