  We compute ghost and gluon propagators of Yang-Mills theory in the Landau
gauge at non-vanishing temperature within a functional renormalisation group
setting. We construct purely thermal flows, that project onto thermal
fluctuations only. For temperatures and momenta above the
confinement-deconfinement temperature Tc the electric propagator shows a
thermal suppression due to Debye screening. The magnetic gluon propagator shows
a thermal scaling and tends towards the three-dimensional one. In this region
both propagators match the lattice propagators. The thermal scaling is also
reflected in the infrared suppression of the ghost-gluon vertex. For
temperatures below Tc the electric propagator shows an enhancement which is in
qualitative agreement with the lattice behaviour.
