2. Sarking - Wikipedia

   en.wikipedia.org/wiki/Sarking

   It acts as additional radiative (radiant barrier) and convective insulation and provides a condensation barrier. [1] In New Zealand, both corrugated metal and asbestos-cement shingle roofs were fitted directly over wooden sarking boards in the historical "bungalow" style of house construction. [2] [3]

3. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface. Radiant barriers are more effective in hot climates than in cooler/cold climates (especially when cooling air ducts are located in the attic). When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot ...

4. Interior radiation control coating - Wikipedia

   en.wikipedia.org/wiki/Interior_radiation_control...

   The energy conserving property has been defined as thermal emittance (the ability of a surface to release radiant energy that it has absorbed). Those coatings qualified as Interior Radiation Control Coatings must show a thermal emittance of 0.25 or less. This means that an IRCCS will block 75% or more of the radiant heat transfer. These low "E ...

5. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Radiant barriers prevent radiant heat transfer equally in both directions. However, heat flow to and from surfaces also occurs via convection, which in some geometries is different in different directions. Reflective aluminum foil is the most common material used as a radiant barrier. It has no significant mass to absorb and retain heat.

6. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   Some radiant barriers are spectrally selective and will preferentially reduce the flow of infra-red radiation in comparison to other wavelengths. For instance, low-emissivity (low-e) windows will transmit light and short-wave infra-red energy into a building but reflect the long-wave infra-red radiation generated by interior furnishings ...

7. Reflective surfaces (climate engineering) - Wikipedia

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

   A perfect roof would absorb no heat in the summer and lose no heat in the winter. 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 ...
