2. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   Another method of applying a radiant barrier to a roof in new construction is to use a radiant barrier that is pre-laminated to OSB panels or roof sheathing. Manufacturers of this installation method often tout the savings in labor costs in using a product that serves as roof decking and radiant barrier in one.

3. Sarking - Wikipedia

   en.wikipedia.org/wiki/Sarking

   In modern usage of the term in Australia, sarking refers to a laminated aluminium foil layer, or reflective foil laminate (RFL), that is installed on the roof trusses, beneath the battens, supporting a tile or metal deck roof. It acts as additional radiative (radiant barrier) and convective insulation and provides a condensation barrier. [1]

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. Oriented strand board - Wikipedia

   en.wikipedia.org/wiki/Oriented_strand_board

   The most common uses are as sheathing in walls, flooring, and roof decking. For exterior wall applications, panels are available with a radiant-barrier layer laminated to one side; this eases installation and increases energy performance of the building envelope. OSB is also used in furniture production.

6. 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.

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 ...
