Bi-Fold & Accordion Doors

A guide to bi-fold and accordion doors

Bi-fold doors, also called accordion or folding doors, are made of glass panels that fold against each other and stack to one side of the opening. PINKYS builds bifold doors in steel with large glass panels, for patios, gardens and indoor rooms. The guide below covers how they work, where they fit and what they are made of.

Folding patio doors and exterior bifold doors

As patio doors, bi-fold doors open almost the full width of the opening, connecting a living room, kitchen or covered patio to the outdoors. Folded open, they make a wide, uninterrupted passage for people, air and light; closed, the slim steel frames and expansive glass keep the view. Bi-fold doors are also a popular choice for garage conversions and ADUs, where a wall of glass makes a smaller space feel brighter and more connected to the outdoors.

Indoor folding doors

Inside the home, bi-fold doors are installed in a framed opening between two rooms, such as a living room and a home office or a kitchen and a dining room. Closed, they separate the spaces while the glass keeps light moving between them; folded open, the two rooms work as one.

Materials and glass

Every PINKYS bi-fold door is built with cold-rolled galvanized steel and comes standard with Low-E dual-pane tempered glass. Choose clear or textured glass to suit the room, and a finish to match the home. Custom colors are available for an added cost.

Care and finish

Every PINKYS door is protected by an eight-stage coating system. Do not repaint a PINKYS door; any repainting voids the warranty. PINKYS offers touch-up paint for minor scuffs and chips.
