Common Security Myths About Bifold Doors: What You Need to Know
Bifold doors are a popular choice for modern homes, offering light-filled interiors, seamless indoor-outdoor living, and a stylish aesthetic. Despite their growing popularity, many homeowners are concerned about bifold door security. Unfortunately, these concerns are often based on misconceptions.
In this blog, we debunk the most common security myths about bifold doors and explain how you can enjoy their style without compromising home security.
Myth 1: Bifold Doors Are Always Less Secure Than Standard Doors
This is simply not true. Modern bifold doors can be just as secure—or even more secure—than traditional doors when properly installed. The key is the locking system, handles, and glass type:
- Multi-point locks secure the door at multiple points along the frame
- Reinforced handles resist tampering and forced entry
- Laminated or toughened glass adds strength and durability
Older bifold doors or poorly installed doors are usually the source of this misconception. With the right security features, a modern bifold door is extremely safe.
Myth 2: Glass Doors Are Easy to Break Into
It’s true that any glass door is a potential entry point. However, modern bifold doors use high-security glass options:
- Toughened glass is five times stronger than standard glass
- Laminated glass contains a plastic interlayer that holds shards together even if broken
These measures make it very difficult for intruders to gain access through the glass, significantly reducing the risk of break-ins.
Myth 3: Locking the Door Is Unnecessary If It’s Visible
Some homeowners assume that a door in plain view of the street or garden doesn’t need locking. This is a mistake. Unlocked doors are an easy target for opportunist burglars, regardless of visibility. In fact, 10% of all burglaries gain access through an open door!
Always:
- Lock your bifold doors when not in use
- Consider additional deterrents such as motion-sensor lighting, outdoor security cameras, or smart door sensors
Visibility alone is not a substitute for proper security.
Myth 4: Aluminium Doors Don’t Need Extra Protection
Aluminium doors are strong and durable but relying solely on the material is not enough. Even aluminium doors benefit from additional security measures, including:
- High-security cylinder locks, such as British Standard or Anti-Snap
- Internal beading to prevent glass removal
- Reinforced handles
Security is about the complete system, not just the door material. Combining strong construction with modern security features provides the best protection.
Myth 5: DIY Upgrades Are Always Enough
While DIY security improvements can help, they often don’t meet professional standards. Professional installation of locks, glazing, and reinforcement devices ensures your bifold doors are fully secure.
Improper installation, loose locks, or poorly fitted glass can create vulnerabilities that DIY solutions can’t fix. For maximum protection, it’s best to consult a professional locksmith.
Takeaway: Bifold Doors Are Safe When Properly Secured
Modern bifold doors are safe, stylish, and highly secure when fitted with:
- Multi-point locking systems
- Laminated or toughened glass
- Reinforced handles and internal beading
- Professional installation and regular maintenance
Understanding these myths helps homeowners make informed decisions and enjoy the full benefits of bifold doors without compromising security.
