    en.wikipedia.org/wiki/Wool_insulation

    Natural wool insulation is effective for both thermal and acoustic insulation. The wool is often sourced from the less expensive black wools of the UK and Europe. [1] Batts are commonly used in the walls and ceilings of timber-frame buildings, rolls can be cut to size for lofts, and ropes can be used between the logs in log homes. Wool knops ...

    Common insulation applications in an apartment building. According to a mineral wool manufacturer, the first mineral wool intended for high-temperature applications was invented in the United States in 1942 but was not commercially viable until approximately 1953. More forms of mineral wool became available in the 1970s and 1980s. [4]

    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 ]

    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.
