On this high-level windows project in Anfield, sealant joints is the first installation control and we allow a practical perimeter joint for movement and a neat external seal line, with sealant joints kept as the lead check for this high-level windows scope. Kaizen Windows & Doors links handle positions to handle position, restrictors, opening angle, installation access and internal reveal, making sure we check handle height and access against the room layout and opening style, with sealant joints kept as the lead check for this high-level windows scope. We also review internal making good before making good and repair or finish internal reveals, sill zones and decoration interfaces around the new frame, with sealant joints kept as the lead check for this high-level windows scope. Finally, reveal dimensions is checked so we can check internal and external reveal depths so trims, plaster and handle clearances can be coordinated, helping deliver high-level glazing configured for practical controlled ventilation, with sealant joints kept as the lead check for this high-level windows scope.
