Heat Reflective Material For Roof

The most well known type of reflective surface is the cool roof.

Heat reflective material for roof.

Re cover the roof with a new waterproofing surface such as tile coating replace the roof with a cool one. 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. The attic under the roof. By reducing the amount of this heat transfer solar reflective shingles and.

A high thermal emittance is preferable in warmer areas so that the heat is not held within the roof and therefore the building. Retrofit the roof with specialized heat reflective material. In the case of air conditioned spaces the power consumption is reduced due to the lowered temperature gradient across the slab. Cool protective coatings can be reapplied repeatedly every 10 to 15 years and will reduce and may eliminate the need for expensive tear offs.

Initial material costs are comparable with traditional roofing materials some cool roof products cost less than traditional materials some cost up to 20 more. 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. Its application reduces roof temperature and correspondingly reduces room temperature. Thermal emittance refers to a roof s ability to release absorbed heat.

Meanwhile conventional roofing materials only reflect a mere 5 to 15 of this energy. Building owners and roofing contractors have used cool roofing products for more than 20 years on commercial industrial and residential buildings. 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. Reflect tec combines industry leading kynar aquatec technology with patented heat reflective technology making it a superior one component coating.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. Some studies show that radiant barriers can reduce cooling costs 5 to 10 when used in a. Reflective surfaces are a form of geoengineering. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.

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. 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.
