Kaizen Windows & Doors plans top-hung windows in Swinton around details that are harder to correct after finishing. The first control is trims, and we coordinate internal or external trims with reveals, frame position and adjoining finishes, with trims kept as the lead check for this top-hung windows scope. We then coordinate frame position through head clearance, hinge line, handle reach, restrictors and weather seals and set the new frame at a position that works with the reveals, sill and external finish, with trims kept as the lead check for this top-hung windows scope. Frame Alignment is checked before closure, while hinge positions is included in final handover. We check the frame for line, level and square before glazing and final tightening and set opening sashes so hinge direction and swing work with the adjoining room, keeping the installation focused on top-hung windows configured around ventilation and practical operation, with trims kept as the lead check for this top-hung windows scope.
