A subframe modal logic is a logic whose class of (general) frames is closed under the formation of subframes. The paper investigates the structure of various lattices of subframe uni- and polymodal logics (in particular, containing K, K4, polymodal \(\text{Alt}_n\), minimal tense extensions of unimodal logics). The main technical tool is the lattice-theoretic notion of splitting.
