2. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   When radiant solar energy strikes a roof, heating the roofing material (shingles, tiles or roofing sheets) and roof sheathing by conduction, it causes the underside of the roof surface and the roof framing to radiate heat downward through the roof space (attic / ceiling cavity) toward the attic floor / upper ceiling surface.

3. 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.

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 - 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.

6. Reflective surfaces (climate engineering) - Wikipedia

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

   The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
