For picture windows in Buckshaw Village, the technical sequence begins with final checks, so we open, close, lock and inspect each installed window before the work is handed over, with final checks kept as the lead check for this picture windows scope. We then use sill level to coordinate opening dimensions, glass specification, frame support, drainage and perimeter sealing, and we coordinate the frame base with the internal sill or window board and the external weathering detail, with final checks kept as the lead check for this picture windows scope. Before closure, drainage paths is reviewed and we keep designed frame drainage routes clear through installation and external finishing, with final checks kept as the lead check for this picture windows scope. The handover also covers opening configuration; we confirm fixed and opening sections against ventilation, access and furniture or worktop positions, with final checks kept as the lead check for this picture windows scope. Together these checks support a broad glazed area with the frame and glass coordinated to the opening.
