Marvin Ultimate Bi-Fold Doors

Marvin Bi-fold

Bifold doors, aka folding or accordion doors have two or more hinged panels that when open stack on the side of the opening. Designed with narrow profiles for less frame and more view, Marvin Bifold doors are well made, energy efficient and a popular style for patio doors.

The floor to ceiling glass panels are hung from above for effortless operation to open or close. Because bifolds stack to the side, out of the way, they are a good choice for high traffic areas. And if space allows, adding a swing door for passage is a nice addition.

Design options include finish, glass, screens and hardware. Available in Elevate and Ultimate product lines.

Marvin Multi-Slide Doors

Marvin Multi-slide Doors

From a kitchen pass through for a deck to a wide open expanse of space, these multi slide doors bring the inside outside. Doors slide or glide with one or more panels aligned in a row and when open stack side by side or disappear into a wall pocket, taking minimal floor space.

When closed the stile of one panel overlaps the stile of the next panel creating a weather tight seal while providing narrow sightlines. Marvin Multi-slide doors can cover huge openings up to 12ft tall and over 50ft wide with floor to ceiling expanse of glass.

Design options include finish, glass, screens and hardware. Available in Signature Modern and Ultimate product lines.
