2. 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.

3. 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.

   en.wikipedia.org/wiki/Rockwool_International

   Rockwool was the world's largest maker of insulation materials in 2009, [6] but had fallen to the second largest by 2016. [7] As of 2009, 90% of the company's revenue came from the sale of insulation products, while 80% came from sales in Europe. [6]

5. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Sheep's wool insulation is a very efficient thermal insulator with a similar performance to fiberglass, approximately R13-R16 for a 4-inch-thick layer. [24] Sheep's wool has no reduction in performance even when condensation is present, but its fire retarding treatment can deteriorate through repeated moisture. [ 25 ]

6. External wall insulation - Wikipedia

   en.wikipedia.org/wiki/External_wall_insulation

   Types of External cromatic wall insulation systems (EWI Systems pictured above) An external wall insulation system (or EWIS) is a thermally insulated, protective, and decorative exterior cladding procedure involving the use of expanded polystyrene, mineral wool, polyurethane foam or phenolic foam, topped off with a reinforced cement based, mineral or synthetic finish and plaster.
