  2. Roof coating - Wikipedia

    en.wikipedia.org/wiki/Roof_coating

    Prepping the seams on a Metal Roof Prior to the Application of a Roof Coating Top coating a commercial flat roof with a cool roof test. Roof coatings are easy to install. Smaller roofs in good, serviceable condition can be a weekend do-it-yourself (DIY) project. Larger roofs with leaks and ponding water issues should be coated by a qualified ...

  3. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    An existing (or new) roof can be made reflective by applying a solar reflective coating to its surface. The reflectivity and emissivity ratings for over 500 reflective coatings can be found in the Cool Roofs Rating Council. [26]

  4. Glossmeter - Wikipedia

    en.wikipedia.org/wiki/Glossmeter

    The surface has less reflective contrast and a shallow milky effect. Orange peel is caused by an uneven surface formation of large surface structures distorting the reflected light. Poor reflective contrast and shallow milky effect. Two high gloss surfaces can measure identically with a standard glossmeter but can be visually very different.

  5. Optical coating - Wikipedia

    en.wikipedia.org/wiki/Optical_coating

    One type of optical coating is an anti-reflective coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and camera lenses. Another type is the high-reflector coating , which can be used to produce mirrors that reflect greater than 99.99% of the light that falls on them.

  6. Metal roof - Wikipedia

    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.

  7. Emissivity - Wikipedia

    en.wikipedia.org/wiki/Emissivity

    This facilitates radiative cooling and protection of the underlying structure and is an alternative to ablative coatings, used in single-use reentry capsules. Passive daytime radiative cooling Daytime passive radiative coolers use the extremely cold temperature of outer space (~2.7 K) to emit heat and lower ambient temperatures while requiring ...

  8. Insulative paint - Wikipedia

    en.wikipedia.org/wiki/Insulative_paint

    Insulative paints, or insulating paints, are a specially designed type of paint in which can be used to coat a surface (e.g a wall) to reduce heat transfer as well as increase the thermal insulating property (R-value in order to aid cooling and heating efforts for example [1].

  9. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    An anti-reflective coating can be deposited on the inner and outer surfaces of such tubes to improve transparency. Both selective and anti-reflective coating (inner tube surface) will not degrade until the vacuum is lost. [8] A high vacuum-tight glass-metal seal is however required at one or both sides of each evacuated tube. This seal is ...
