Temperature Reducing Roof Paint

Reflective roof coatings increase your energy efficiency.

Temperature reducing roof paint.

If you haven t encountered reflective roof coatings these are coatings you apply to metal and rubber roofs to reduce heat from roof top. Most are not easy to apply to existing roofs and walls but a. It is a sun reflective paint and aims to reduce the roof temperature. Colder temperatures and moisture on the surface can also result in staining or mildew.

Usually the color of the roof is dark and it is a common knowledge that the sun heat upon the dar color has much more impact than that of the lighter color. The reason or logic behind the cooling roof paint to reduce the temperature is that it acts as a coating over the surface of the roof. This means that your cooling. The heat reflective paint lessens the urban heat islands effect which allows cooler buildings.

However the technological expertise of astec paints opens up colour options in black or deep tone for roofs and surfaces that would reflect solar heat and stay cool. Lo mit i is an energy star certified radiant barrier roof coating that is formulated to reduce roofing surface temperatures at low cost. Lo mit is a silver colored non thickness dependent low emissivity paint which may be used in almost any application where infrared heat reflectivity or diffuse light reflectivity is required. As for humidity levels the best drying will occur between 40 and 70 percent humidity.

First the coating reflects sunlight the moment it hits your roofing surface. Also called an evaporative cooling system a roof misting system lowers surface temperatures by spraying an extremely small amount of water across the roof allowing the water to cool the roof as it evaporates. Some manufacturers now claim that certain paints will cure in temperatures as low as 35 f. For latex based paints it s 50 to 85 degrees.

Researchers are building on that age old strategy with a new wave of passive radiative cooling materials that shed sunlight and heat. For an oil based paint the best temperature to apply is between 40 and 90 degrees fahrenheit. It is a thermal insulating roof coating and which minimises the solar heat coming to the roof. Coolroof is a high sri and high albedo coating which can be applied on all types of roofs.

Reflective coatings work one out of two ways. But by how much and are there downsides to doing it. If you d rather enjoy the benefits of a cool roof without the addition of new surface materials or coatings consider a roof mist cooling system.
