CF68 / CF77

​The Concept Folding (CF) series of folding sliding doors from Reynaers aluminium consists of two separate systems, each with their own characteristics designed for different scenarios.

The CF68 bi-folding door is a more domestic system designed with slimmer frames, allowing more glass to be on show which creates a slightly lower U-value. The CF77 system has slightly larger frames which allows for large panels and robust mechanisms making it ideal for commercial, as well as domestic, applications.
