3. List of insulation materials - Wikipedia

   en.wikipedia.org/wiki/List_of_insulation_materials

   This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

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

   R. -value (insulation) 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. [3]. R-value is the temperature difference per unit of heat flux needed to sustain one unit of ...

6. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, [1][2] especially when buildings are heated by oil, natural gas, or coal-based electricity.
