For this bow windows project in Prenton, opening checks, frame fitting and finishing are treated as one sequence. Head Interface leads the review, so we coordinate the frame head with the retained lintel, cavity closure and internal reveal, with head interface kept as the lead check for this bow windows scope. We use perimeter sealing and glazing beads around frame segmentation, connectors, sill line, head interface and internal finishing, ensuring we form a continuous weather-resistant seal around the external frame perimeter and check bead seating and corner joints after the glass is installed, with head interface kept as the lead check for this bow windows scope. The last technical check is removal sequence; we remove existing frames in a controlled order to protect the opening and adjoining finishes, with head interface kept as the lead check for this bow windows scope. This supports a multi-frame bow arrangement coordinated as one installation rather than separate windows.
