   en.wikipedia.org/wiki/Cork_thermal_insulation

   The thermal efficiency and hygrothermal behaviour of timber frame walls with various external insulation layers were studied by Fu et al. [15] They observed that expanded cork panels provide better hygrothermal performance and building comfort than an anti-corrosion pine board.

5. External wall insulation - Wikipedia

   The brick slips usually have a size of about 210-240 x 50-71 x 20 mm (length x height x width). Simulated brick renders can also be replicated in coloured polymer to a high standard. Two coloured layers of polymer-modified external cementitious render are applied in 3 to 4 millimetres (0.12 to 0.16 in) layers onto a coloured backing.

6. R-value (insulation) - Wikipedia

   en.wikipedia.org/wiki/R-value_(insulation)

   Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value (in K⋅m 2 /W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction.
