The structural and dynamical properties of densified sodium silicates are investigated using
molecular dynamics (MD) simulations. From the analysis of the first sharp diffraction peak
(FSDP) in the amorphous phase, it is shown that some of its characteristic parameters
(position, width) in partial structure factors display minima in a certain pressure interval
defining a window. The pressure window can be correlated with anomalies in transport
properties (diffusion, viscosity) and their activation barriers. The count of topological
