Heat Reflective Material For Roof

Reflective surfaces can deliver high solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the surface and high thermal emittance the ability to radiate absorbed or non reflected solar energy.

Heat reflective material for roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. In the case of air conditioned spaces the power consumption is reduced due to the lowered temperature gradient across the slab. The tex cote reflect tec coating system is a revolutionary field applied infrared heat reflective coating specifically designed for metal and tile roof and wall surfaces. Retrofit the roof with specialized heat reflective material.

Solar reflective shingles are designed specifically to reduce the absorption of the suns infrared radiation by reflecting ir rays off the surface of the roof thus not allowing the heat to be transferred to the interior of the structure i e. Building owners and roofing contractors have used cool roofing products for more than 20 years on commercial industrial and residential buildings. Some studies show that radiant barriers can reduce cooling costs 5 to 10 when used in a. Cool paint is a heat reflective paint and this paint has been designed to reflect more sunlight and absorb less heat than a standard roof.

Reflective roof coatings also known as albedo coatings are products applied to roofs to reduce solar heat especially in areas with hot sunny weather for a good part of the year. Reflective surfaces are a form of geoengineering. Re cover the roof with a new waterproofing surface such as tile coating replace the roof with a cool one. If your roof is in poor condition or near the end of its life it is usually best to re cover replace or retrofit the roof.

A high thermal emittance is preferable in warmer areas so that the heat is not held within the roof and therefore the building. Because they can reduce surface temperatures by up to 80 f about 45 c these products also have a big impact on cooling costs. Initial material costs are comparable with traditional roofing materials some cool roof products cost less than traditional materials some cost up to 20 more. Thermal emittance refers to a roof s ability to release absorbed heat.

By reducing the amount of this heat transfer solar reflective shingles and. Reflect tec combines industry leading kynar aquatec technology with patented heat reflective technology making it a superior one component coating. Its application reduces roof temperature and correspondingly reduces room temperature. Together these properties help roofs to absorb less heat and stay up to 50 60 f 28 33 c cooler than conventional materials during peak summer weather.

Meanwhile conventional roofing materials only reflect a mere 5 to 15 of this energy. The attic under the roof.
