On this thermal-upgrade windows project in Mold, gaskets is the first installation control and we check glazing and sash seals for continuous seating before final handover, with gaskets kept as the lead check for this thermal-upgrade windows scope. Kaizen Windows & Doors links trims to glass specification, frame perimeter, cavity interface, seals and internal reveals, making sure we coordinate internal or external trims with reveals, frame position and adjoining finishes, with gaskets kept as the lead check for this thermal-upgrade 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 gaskets kept as the lead check for this thermal-upgrade windows scope. Finally, frame alignment is checked so we can check the frame for line, level and square before glazing and final tightening, helping deliver replacement glazing with the frame perimeter and surrounding junctions coordinated for thermal continuity, with gaskets kept as the lead check for this thermal-upgrade windows scope.
