  We study the phase transition in SU(2)-Higgs model on the lattice using the
3D dimensionally reduced formalism. The 3D formalism enables us to obtain
highly accurate Monte Carlo results, which we extrapolate both to the infinite
volume and to the continuum limit. Our formalism also provides for a
well-determined and unique way to relate the results to the perturbation
theory. We measure the critical temperature, latent heat and interface tension
for Higgs masses up to 70 GeV.
