Invite nature into your building

From 2 to 8 vents, opening any way you want
ConceptFolding 77 is Reynaers aluminium folding door system that turns whole walls into openings. Slim, insulated 77 mm profiles carry large glass panels up to three metres high, in layouts from two to eight leaves, opening in or out on smooth floor rollers for a clean indoor outdoor connection.
Thermal breaks and tight seals deliver strong insulation and weather performance, helping keep interiors comfortable and energy use down. Four threshold solutions cover everything from high performance weathered sills to flat, barrier free floors for busy entrances.
Two design lines – Functional and the even slimmer CF 77 Slim Line – keep sightlines lean while meeting RC2 security requirements. The lead leaf can work as a daily use door, so you get a practical entrance most of the time and a full opening when the space needs to breathe.
The MasterPatio at a glance:
ConceptFolding 77 comes in two design lines with the same performance but a different look: Functional for a clean, robust profile and SlimLine for even slimmer sightlines and a lighter feel. Both offer standard or high insulation for comfort in any climate, with a burglar resistant variant for added security.

Functional
The standard product offers a Functional design, which means it will fit any building style.

SlimLine
The SlimLine design creates a lighter visual appearance when the door is closed.
