The automotive industry is witnessing a transition in vehicle design to a preferred styling trend known as flush glass (or flush glazing), alongside the shift to hybrid and electric vehicles. This trend creates a sleek and aerodynamic appearance down the side glass of the vehicle which traditionally is only capable with frameless door architectures. Cooper Standard introduced FlushSeal™ to bridge the gap between traditional door and frameless door architectures, while still meeting performance requirements. This side-door sealing system gives the appearance of a seamless flush-side glass, with the ability to fit around the structure of a traditional doorframe.




FlushSeal™ Sealing System’s seamless integration gives vehicles a clean, modern look. It merges style with cutting-edge technology to improve both vehicle appearance and performance. With a patented design, this solution uses special rails to provide robust glass positioning, with the combination of easy sliding of the regulator for the smooth transition of the B-Pillar glass. The technology can be created using different materials for customers looking for specific styling or sustainable alternatives, including our Fortrex™ material family.
Features & Benefits:
- Smooth glass body surface transition
- ~5 kg door weight reduction compared to frameless doors
- Superior window positioning with optimized clearance
- Versatile design and assembly
