2. 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.

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.

   Class II, Semi-impermeable (0.1-1 US perm, or 5.7-57 SI perm) – such as unfaced expanded or extruded polystyrene, OSB, fiber-faced isocyanurate, 30 pound asphalt-impregnated building papers, exterior oil-based paints, unfaced expanded polystyrene, 30 pound asphalt coated paper, plywood, bitumen coated kraft paper;

5. Electrical insulation paper - Wikipedia

   en.wikipedia.org/wiki/Electrical_insulation_paper

   Electrical insulation papers are paper types that are used as electrical insulation in many applications due to pure cellulose having outstanding electrical properties. Cellulose is a good insulator and is also polar , having a dielectric constant significantly greater than one. [ 1 ]

7. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   The TVA study [12] also tested a double-sided radiant barrier with black plastic draped on top to simulate heavy dust accumulation, as well as a single-sided radiant barrier with heavy kraft paper on the top. The test indicated that the radiant barrier was not performing, and the small air spaces created between the peaks of the insulation were ...
