We show that strong first-order phase transitions (FOPTs) can occur provided that appropriate source of $\\mathbb{Z}_2$ symmetry breaking between the twin and Standard Model (SM) sectors is present. We found FOPTs in two classes of models. First: with hard $\\mathbb{Z}_2$ breaking in the scalar potential allowing for FOPT. Second: with $\\mathbb{Z}_2$ broken by enhanced Yukawa couplings of twin leptons. We also considered supersymmetric UV completion of the second scenario with light sleptons.
