Bi-fold doors are now a hallmark of modern architecture, loved for their ability to connect indoor and outdoor spaces while filling interiors with natural light. But behind their elegance, one important question often comes up: Are bi-fold doors secure?
At Eris Home Products, we believe style should never come at the expense of safety. That’s why our bi-fold doors are built with advanced security features, durable materials, and professional installation practices to give homeowners peace of mind.
Let’s explore the features that make Eris bi-fold doors a strong and reliable choice.
Multi-Point Locking Mechanism
Every Eris bi-fold door includes a multi-point locking system, the cornerstone of our security design. Instead of relying on a single latch, multiple locks are engaged along the frame.
This system uses a cylinder lock with a pin-and-tumbler mechanism, securing the door at several points to resist prying or forced entry.
Tailored Security Options
Security isn’t one-size-fits-all. Depending on door size and configuration, Eris bi-folds can be fitted with 6-point or 8-point locking systems, ensuring that each panel is fortified appropriately with no weak spots.
Twinpoint Locks
For additional reinforcement, our doors feature twinpoint locks operated from a central handle. These anchor the door at both the top and bottom, locking panels firmly into place while keeping operation simple and stylish.
Dropbolts and Deadbolts
Dropbolts, positioned at the top and bottom of the doors, add another layer of defense. We also integrate deadbolts—either keyed or internal—which act as a final safeguard against intrusion.
The materials used in a bi-fold door frame directly impact both its strength and resistance to tampering. Eris offers designs built from durable, low-maintenance materials that resist wear and protect your home over the long term.
Bi-fold doors maximize natural light with wide glass surfaces, but that doesn’t mean compromising security. At Eris, we use impact-resistant glass options that hold strong against breakage.
Along with robust seals and gaskets, our glass panels fit tightly into frames, preventing removal or tampering. These seals also improve insulation, keeping interiors comfortable.
Even the strongest doors need proper installation to perform at their best. That’s why Eris recommends expert fitting by trained installers.
Some homeowners worry bi-fold doors might be less secure than sliding or French doors. The reality is quite the opposite.
Sliding doors often rely on a single lock at the handle. Over time, they can develop alignment issues, creating gaps intruders can exploit. Bi-fold doors, with multiple locking points across the frame, distribute pressure evenly, making them far harder to force open.
French doors usually secure with bolts at the top and bottom, but their central seam can still be vulnerable. In contrast, bi-fold doors have overlapping panels that interlock when closed, creating a stronger, layered barrier. Advanced seals further reduce any weak points.
The interlocking panel design of bi-fold doors means every section reinforces the next. Add multi-point locking, laminated glass, and high-strength frames, and the result is a barrier that’s not only stylish but extremely difficult to breach.
In security, time is critical—and Eris bi-fold doors are built to delay and deter intruders long enough that most abandon the attempt.
For those who want even more peace of mind, Eris bi-fold doors can be enhanced with advanced security technology:
At Eris Home Products, we design bi-fold doors that are as secure as they are stylish. From advanced locking systems and reinforced glass to durable frames and smart upgrades, every detail is engineered for protection.
With proper installation and maintenance, Eris bi-fold doors deliver lasting security for homes and businesses alike.
With Eris, elegance meets protection—giving you the freedom to enjoy open, light-filled spaces without compromising peace of mind.
What is the strongest material for bi-fold door frames?
Aluminum and composite frames provide the best balance of durability, security, and low maintenance.
Do multi-point locks improve security?
Yes. By fastening the door at multiple points, they make it much harder for intruders to pry open.
Which glass is best for security?
Laminated and tempered glass both offer superior resistance to impacts compared to standard glass.
Should I hire professionals for installation?
Absolutely. Proper alignment and secure hardware installation are critical to door security.
How often should I service my bi-fold doors?
Check locks, hinges, and seals at least twice a year for smooth operation and maximum security.
