Window performance on this plastered-reveal windows installation in Oldham depends on more than the frame profile. We start with thermal junctions and coordinate the frame perimeter with insulated reveals or cavity details to limit avoidable cold bridging, with thermal junctions kept as the lead check for this plastered-reveal windows scope. final checks is then coordinated through frame position, plaster edge, corner protection, sill finish and drying sequence, so we open, close, lock and inspect each installed window before the work is handed over, with thermal junctions kept as the lead check for this plastered-reveal windows scope. Before final finishing, we review sill level and coordinate the frame base with the internal sill or window board and the external weathering detail, with thermal junctions kept as the lead check for this plastered-reveal windows scope. We finish with packers and support the frame at suitable points so fixing does not pull it out of line, supporting plastered reveals finished cleanly around the replacement frame, with thermal junctions kept as the lead check for this plastered-reveal windows scope.
