On this fixed-pane windows project in Penkridge, internal making good is the first installation control and we repair or finish internal reveals, sill zones and decoration interfaces around the new frame. Kaizen Windows & Doors links reveal dimensions to frame dimensions, glass size, sightlines, drainage and perimeter sealing, making sure we check internal and external reveal depths so trims, plaster and handle clearances can be coordinated, with internal making good kept as the lead check for this fixed-pane windows scope. We also review frame alignment before making good and check the frame for line, level and square before glazing and final tightening, with internal making good kept as the lead check for this fixed-pane windows scope. Finally, glass specification is checked so we can match glazing type and pane configuration to the intended room use and project specification, helping deliver fixed glazing with a clean frame line and no unnecessary opening hardware, with internal making good kept as the lead check for this fixed-pane windows scope.
