Reflect Heat From Roof

The surface of a cool roof reflects more sunlight and releases more heat than a so called hot or dark roof.

Reflect heat from roof.

When a radiant barrier is placed between the roofing material and the insulation on the attic floor much of the heat radiated from the hot roof is reflected back toward the roof and the low emissivity of the underside of the radiant barrier means that very little radiant heat is emitted downwards. Metal roofs not only have 25 95 recycled content depending on the material used but are also 100 recyclable at the end of their life as a roof. Reflect tec combines industry leading kynar aquatec technology with patented heat reflective technology making it a superior one component coating. A cool roof is a roof designed to maintain a lower surface temperature in bright sunshine than a traditional roof source.

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. There are few green building choices smarter than a cool roof in hot climates. Not only that but white paints also reflect heat at infrared wavelengths which a human eye cannot see and. Use light color metal roof with overhangs to shade the walls on the south and west sides.

The attic under the roof. Infrared radiation is a spectrum of light that generates significant amounts of heat on roof surfaces. I can tell you that my experience is that any metal roof is cooler than asphalt shingles. The leed for homes rating system even rewards points for buildings who s roof surface meets a certain reflective criteria 29 sri solar reflective index what is new about this is that it is a doubled layer paint so it has heat reflective qualities but it is not limited to white.

The best way to beat the heat is to not absorb it in the first place. A radiant barrier is simply a sheet of aluminum foil with a paper backing. When installed correctly a radiant barrier can reduce heat gains through your ceiling by about 25 percent. 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.

Another way to reflect heat is to install a radiant barrier on the underside of your roof. Metal roofs reflect solar radiant heat which can reduce cooling costs by 10 25.
