Observed FIR SEDs at $z\\gtrsim5$ are broad and shifted to bluer wavelengths when compared to galaxies at $z\\sim3$. By implementing an analytical model for dust emission from Pop II massive galaxies,we were able to reproduce the observed behaviour as a consequence of the high energy densities and silicate-rich dust composition of high-$z$ model galaxies.
