A Georgian style insulating grid, comprising horizontal profiles (10) and vertical profiles (20) connected to one another to make any type of divider elements inside insulating glass units, each of said profiles (10, 20) comprising an elongated body (5) made in plastic material or the like, and at least one metal insert (6), which extends for at least one portion of the length of said elongated body (5), at least partially embedded in said elongated body (5), said elongated body (5) having a substantially tubular cross-section and defining at least one inner cavity (8), said grid (1) moreover comprising means (30) for connecting at least two opposite profiles (10, 20) to one another. The metal insert (6) of at least one of said profiles (10, 20) passes through said inner cavity (8) and has its ends (9) embedded in said elongated body (5), so as to define at least one seat (40;40,41) for inserting said reciprocal connection means (30).
