  We consider a scale symmetric extension of the Standard Model Higgs scalar
sector. The new sector, dilaton, is responsible for the generation of mass
scales and may have geometric origin in the Weyl gravity $\tilde{R}^2$ term. We
show how temperature as a mass scale breaks scale symmetry explicitly and
through a nonvanishing thermal vev. In addition we demonstrate that
cosmological evolution of the dilaton-Higgs system can lead to late time mass
scales, which agree with the Standard Model.
