Aluminium bifold doors are a stunning way to open up your living space, but how do they measure up when it comes to home security? With sleek sightlines and expansive glazing, it’s natural to wonder whether style compromises safety. The good news: modern aluminium bifold systems—especially those from trusted brands like Cortizo and Sheerline—are engineered with security at their core.
Here’s what makes them a robust choice for peace of mind:
Multi-Point Locking Systems
Security starts with the locking mechanism. Both Cortizo and Sheerline bifold doors feature advanced multi-point locking systems that secure the door at several points along the track, making it significantly harder to force open than single-point locks. These systems engage top, bottom, and side bolts simultaneously, offering comprehensive protection against intrusion.
Professional Installation Matters
Even the most secure door can be compromised by poor installation. A properly fitted bifold door ensures that all locking points align perfectly and that the frame is anchored securely to the surrounding structure.
High-Security Cylinders
The cylinder is often the weakest link in any door system. That’s why upgrading to a high-security cylinder like Ultion is a smart move. These cylinders are designed to resist snapping, drilling, and picking, and some come with a £2,000 guarantee against break-ins. Ultion cylinders also feature lock-down mode, which activates if forced entry is detected.
Aluminium: Strong, Rigid, and Durable
Unlike timber or uPVC, aluminium offers exceptional rigidity and resistance to warping. Cortizo and Sheerline frames are made from thermally broken aluminium profiles that combine strength with energy efficiency. Their robust construction ensures that the doors remain secure and aligned over time, even with frequent use.
Glazing That Guards
Security glazing is another key layer of protection. Both Cortizo and Sheerline systems can be upgraded to meet PAS24 standards, which include laminated glass—a toughened interlayer that holds the pane together even if shattered. This makes it far more difficult for intruders to gain access through the glass.
PAS24 Certification and Laminated Glass
For homeowners seeking enhanced security, PAS24-certified bifold doors are the gold standard. This certification confirms that the door has passed rigorous testing for resistance to physical attack. Cortizo and Sheerline systems can be specified with PAS24 upgrades, including laminated glass and reinforced hardware, ensuring compliance with building regulations and insurance requirements.
Aluminium bifold doors from Cortizo and Sheerline don’t just look good—they’re built to protect. With multi-point locks, premium cylinders, and PAS24 upgrade options, they offer a reassuring blend of elegance and security. Whether you’re renovating or building new, investing in a secure bifold system means you won’t have to choose between style and safety.
