We consider thermal transport in low dimensional disordered harmonic networks of coupled masses Utilizing known results regarding Anderson localization we derive the actual dependence of the thermal conductance G on the length L of the sample This is required by nanotechnology implementations because for such networks Fourier s law G propto 1 L alpha with alpha 1 is violated In particular we consider glassy disorder in the coupling constants and find an anomaly which is related by duality to the Lifshitz tail regime in the standard Anderson model
