For uPVC windows with Georgian-style bars in Manchester, the technical sequence begins with sill level, so we coordinate the frame base with the internal sill or window board and the external weathering detail, with sill level kept as the lead check for this Georgian-style windows scope. We then use glass specification to coordinate pane proportions, bar layout, opening sections, sightlines and frame finish, and we match glazing type and pane configuration to the intended room use and project specification, with sill level kept as the lead check for this Georgian-style windows scope. Before closure, trims is reviewed and we coordinate internal or external trims with reveals, frame position and adjoining finishes, with sill level kept as the lead check for this Georgian-style windows scope. The handover also covers frame dimensions; we confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with sill level kept as the lead check for this Georgian-style windows scope. Together these checks support decorative glazing proportions coordinated consistently across the window.
