On this tilt-and-turn windows project in Crewe, restrictors is the first installation control and we configure restrictors where controlled opening forms part of the brief. Kaizen Windows & Doors links trims to frame size, opening clearance, handle position, restrictors and surrounding reveals, making sure we coordinate internal or external trims with reveals, frame position and adjoining finishes, with restrictors kept as the lead check for this tilt-and-turn windows scope. We also review frame position before making good and set the new frame at a position that works with the reveals, sill and external finish, with restrictors kept as the lead check for this tilt-and-turn windows scope. Finally, packers is checked so we can support the frame at suitable points so fixing does not pull it out of line, helping deliver tilt-and-turn windows with enough clearance for both operating modes, with restrictors kept as the lead check for this tilt-and-turn windows scope.
