Benefits of FoldFlat® Technology on a Space

Clear Circulation

Occupants are able to walk fully around openings, which is helpful for crowded spaces that need free flowing traffic and clear walkways.

Maximizes Space

Use every inch of a space for its original purpose. Doors that fold entirely against the wall allow full use of spaces or conference rooms.

Expands Views

Folded panels, whether in a window or wall, disappear completely out of the line of sight to create broadened views.

Increases Counter Space

Apply FoldFlat technology to bifolding windows – or the Kitchen Transition – to create extra counter space.
