Their drawbacks when compared to mineral wool are their substantially lower mold resistance, higher combustibility, and slightly higher thermal conductivity (hemp insulation: 0.040 Wm-1 k-1, mineral wool insulation: 0.030-0.045 Wm-1 k-1). [16]

Mineral wool insulation, 1600 dpi scan. Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. [1]
One example is AirKrete, [5] at R-3.9 (RSI-0.69) per inch and no restriction on depth of application. Non-hazardous. Being fireproof, it will not smoke at all upon direct contact with flame, and is a two-hour firewall at a 3.5 in (89 mm) (or normal 2 in × 4 in (51 mm × 102 mm) stud wall) application, per ASTM E-814 testing (UL 1479).
