    To do this it would need a very high SRI to eliminate all radiative heat gains in summer and losses in winter. High SRI roofs act as a radiant barrier, providing a thermos-bottle effect. High emissivity cool roofs carry a climate penalty due to winter radiative heat losses, which reflective bare metal roofs, such as stainless steel, do not.

  3. Roof coating - Wikipedia

    en.wikipedia.org/wiki/Roof_coating

    Many roof coatings are elastomeric, that is, they have elastic properties that allow them to stretch and return to their original shape without damage. Typical roof coating dry film thickness vary from paint film thickness (plus or minus 0.075 mm (3 dry mils) to more than 1 mm (40 dry mils). This means a roof coating actually becomes the top ...

    Terne metal can last 90 years or more if the paint is maintained. Terne-coated stainless steel (TCS II or Roofinox), or copper is commonly used to replace terne metal roofs as either material will outlast terne metal. Terne-coated stainless steel roofing can last 100 years or more unpainted; copper roofing can last 50 years or more unpainted.

    This effect can be seen in the elongation of the Airy disk in the direction perpendicular to the crest of the roof as this is a diffraction from the discontinuity at the roof crest. The unwanted interference effects are suppressed by vapour-depositing a special dielectric coating known as a phase-compensating coating on the roof surfaces of the ...

    According to EN 13523-0, a prepainted metal (or coil coated metal) is a ‘metal on which a coating material (e.g. paint, film…) has been applied by coil coating’.When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or other specific properties.

    en.wikipedia.org/wiki/Metal_roof

    A metal roof is a roofing system featuring metal pieces or tiles exhibiting corrosion resistance, impermeability to water, and long life. It is a component of the building envelope . The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets.
