A Door You Feel Every Day
Bi-Fold Patio Door Advantages — Wider Opening and More Flexible Everyday Use
Alu Fold Plus aluminum bi-fold patio doors are designed to open the space wider while still feeling practical, controlled, and comfortable in everyday use.
How aluminum bi-fold patio doors work
Unlike a standard sliding patio door, a bi-fold patio door does not leave one large fixed glass panel in place. Instead, the glass panels fold and stack to the side, allowing a much larger portion of the opening to be cleared.
More open space when you want it
Alu Fold Plus is ideal when the goal is to turn a patio opening into a wider folding glass wall. These aluminum bi-fold doors let you enjoy a wide, open transition during warm weather, entertaining, or everyday family life — then close everything back into a secure, weather-tight aluminum glass wall.
A low-threshold option for easier walk-through
A low-threshold option also helps create a cleaner, easier walk-through, and the bi-fold patio door can be planned with an embedded threshold for a more seamless transition between inside and outside.
WHY IT STANDS OUT:
Alu Fold Plus gives you the open-wall feel of premium aluminum bi-fold patio doors, while keeping everyday access clean, practical, and comfortable.

Bi-Fold Patio Door Configurations for Wide and Corner Openings
The right aluminum bi-fold patio door should adapt to the opening — from compact patio doors to wide folding glass walls and advanced corner layouts.
Multiple panel layouts, not limited to four panels
Alu Fold Plus bi-fold patio doors are not limited to just 2-panel, 3-panel, or 4-panel configurations. Depending on the project, they can be planned with a wide range of panel counts, from smaller folding patio doors to large multi-panel glass openings.
Daily swing door for everyday access
For better everyday usability, Alu Fold Plus can include a swing traffic door. This allows comfortable passage to a patio, terrace, deck, or backyard without opening the entire bi-fold patio door.
Inswing, outswing, and 90° corner opening
Alu Fold Plus aluminum bi-fold patio doors can be planned for inward or outward opening, depending on interior space, exterior conditions, stacking direction, and architectural goals. For more advanced projects, these aluminum folding patio doors can also create a 90° corner opening without a fixed mullion, allowing two sides of the corner to open for a stronger open-space effect.
WHAT YOU GET:
Flexible aluminum bi-fold patio door configurations with multiple panels, daily swing-door access, inswing or outswing operation, and optional 90° corner opening without a fixed mullion.

Energy Efficiency with Thermally Broken Aluminum and Low-E Glass
Large aluminum bi-fold patio doors should bring in light and openness — without giving up comfort when the doors are closed.
Thermally broken aluminum frame
Alu Fold Plus uses a thermally broken aluminum frame designed to help reduce heat transfer while maintaining the clean, modern look expected from premium aluminum bi-fold patio doors.
Tempered Low-E insulated glass
Combined with tempered Low-E insulated glass, Alu Fold Plus helps improve year-round comfort, support more stable indoor temperatures, and reduce the uncomfortable hot or cold feeling near large glass areas.
Tight closing and weather protection
When closed, the folding patio door panels lock into position to help improve air tightness, water resistance, security, and overall comfort. The result is a serious aluminum bi-fold patio door for everyday living — not just a decorative glass opening.
WHAT YOU GET:
Modern aluminum bi-fold patio doors with strong thermal performance, Low-E insulated glass, better comfort near the opening, and a tighter, more weather-protected close.

Design Freedom with Colors, Handles, and Architectural Details
A premium aluminum bi-fold patio door should feel fully integrated into the architecture — not like a standard add-on product.
Wide range of finishes
Alu Fold Plus aluminum bi-fold patio doors are available in a wide range of finish options, making it easier to coordinate the door with the style of the home. Whether the project calls for classic White, Matte Black, or a more distinctive custom architectural tone, the door offers strong design flexibility. Interior and exterior colors can also be different, helping the bi-fold patio door work visually with both the exterior facade and the interior palette.
Handle and hardware details
Handle options help refine the final look while improving everyday usability. Depending on the layout, the aluminum bi-fold patio door can include a daily traffic door, different access solutions, and hardware selected around the way the door will actually function in daily life.
THE RESULT:
Alu Fold Plus delivers the open-wall effect of aluminum bi-fold patio doors with finish, handle, and configuration options that feel intentionally matched to the architecture.
