2. 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 ...

3. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   One sided radiant barrier may be attached to insulating materials, such as polyisocyanurate, rigid foam, bubble insulation, or oriented strand board (OSB). Reflective tape can be adhered to strips of radiant barrier to make it a contiguous vapor barrier or, alternatively, radiant barrier can be perforated for vapor transmittance.

4. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   Radiant barriers work in conjunction with an air space to reduce radiant heat transfer across the air space. Radiant or reflective insulation reflects heat instead of either absorbing it or letting it pass through. Radiant barriers are often seen used in reducing downward heat flow, because upward heat flow tends to be dominated by convection.

5. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.

6. 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 ...
