Flush Doors at a glance
Flush sash exterior doors offer a sleek finish that suits both traditional and modern homes. Available in PVCu or aluminium, they combine low maintenance with excellent durability, security, and energy efficiency.
Traditional Charm, Contemporary benefits
Both PVCu and aluminium flush doors are available with a foiled finish, and a variety of welding options perfect for replicating a traditional timber appearance - with the performance benefits of modern materials.
Resurgence - double rebated design
Our 80mm Resurgence flush sash system is double-rebated. Because the sash seals on both the outer and inner rebates of the frame, the system delivers enhanced weather protection, improved airtightness, and excellent thermal efficiency.
