Regarding bi-fold doors, which, in your opinion is better, top hung or bottom roller?
Top hung refers to the door being supported by hanging from the track, bottom hung refers to rollers on a bottom track, ‘EcoEco’ is top hung.
Top hung does not suffer from dirty tracks, and bottom hung does not need lintel support.
Our bifold doors are second to none, height to 3000mm, width to 6000mm+, all silicon glazed. Never drop or need adjustment except for building movement. Our bifold window is the same design as the bifold door.
EcoEco EcoTech range: Fixed window and bifold door in colour silver
