On this mixed-window replacement project in Oxton, packers is the first installation control and we support the frame at suitable points so fixing does not pull it out of line, with packers kept as the lead check for this mixed-window replacement scope. Kaizen Windows & Doors links thermal junctions to frame dimensions, opening types, hardware, glazing and installation sequence, making sure we coordinate the frame perimeter with insulated reveals or cavity details to limit avoidable cold bridging, with packers kept as the lead check for this mixed-window replacement scope. We also review trims before making good and coordinate internal or external trims with reveals, frame position and adjoining finishes, with packers kept as the lead check for this mixed-window replacement scope. Finally, surface protection is checked so we can protect floors, worktops and nearby finishes while removal and installation work is carried out, helping deliver different window types installed through one coordinated replacement package, with packers kept as the lead check for this mixed-window replacement scope.
