Bi-fold Gretch-Unitas doors
Bi-fold doors offer the ultimate in living space flexibility. Effectively creating a glass wall that you can slide out of the way to open your living area completely, folding doors offer unrivalled flexibility in how you blend the space between the inside and outside of your home. Folding sliding doors ensure the entire opening is completely clear, with no fixed sections.
