Window performance on this brick-reveal windows installation in Bryn depends on more than the frame profile. We start with sealant joints and allow a practical perimeter joint for movement and a neat external seal line. external making good is then coordinated through reveal dimensions, frame setback, fixing positions, sealant joint and sill line, so we finish external reveals, render or masonry interfaces around the installed frame, with sealant joints kept as the lead check for this brick-reveal windows scope. Before final finishing, we review frame position and set the new frame at a position that works with the reveals, sill and external finish, with sealant joints kept as the lead check for this brick-reveal windows scope. We finish with cavity closure and check the window perimeter where the opening meets cavity closers or insulated reveal construction, supporting a frame position coordinated with visible masonry reveals and external sealing, with sealant joints kept as the lead check for this brick-reveal windows scope.
