The 2$\\omega$-method is used to measure the thermal diffusivity $D$ in [010] and [001] direction respectively and to determine the thermal conductivity values $\\lambda$ of the [100], [010] and [001] direction from the same insulating Mg doped $\\beta$-$\\mathrm{Ga_2O_3}$ single crystal. We detect a temperature independent anisotropy factor of both the thermal diffusivity and conductivity values of $D_{[010]}/D_{[001]}=\\lambda_{[010]}/\\lambda_{[001]}=1.4\\pm 0.1$.
