For this fixed-pane windows project in Burnley, opening checks, frame fitting and finishing are treated as one sequence. Frame Dimensions leads the review, so we confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with frame dimensions kept as the lead check for this fixed-pane windows scope. We use fixing points and sealant joints around frame dimensions, glass size, sightlines, drainage and perimeter sealing, ensuring we position frame fixings to suit the opening, frame profile and surrounding substrate and allow a practical perimeter joint for movement and a neat external seal line, with frame dimensions kept as the lead check for this fixed-pane windows scope. The last technical check is handle positions; we check handle height and access against the room layout and opening style. This supports fixed glazing with a clean frame line and no unnecessary opening hardware.
