Ecoline Flexa
Slim sightlines - maximum transparency
Flexa Ecoline internal bi-folding door
Incredibly slim sightlines, patented technology
The Ecoline Flexa bi-folding door system provides maximum natural light and excellent sound insulation (R = 45 dB), with the option of visual privacy thanks to wholly or partly matted glass panes without sacrificing light.
Moving panels can be parked within the track on the right, left or in the middle, making it equally suitable for flexible glazing of shop entrances where a large opening is required, and for flexible interiors where acoustic separation matters.
The system is intuitive to use, needing no instruction, and swing doors can be planned in where required.
