Manufacturers of bi-folding doors since 2003, SunSeeker Doors began developing a double-glazed version of Frame-less Glass Curtains two years ago. Frameless Glass Doors comply with British Standards and have demonstrated greater thermal values than bi-folds. There are two basic differences:
- Frameless Glass Doors have better sightlines - more glass where frames used to be;
- Unlike bifolding doors, Frameless Glass Doors slide and pivot individually.
