Why French doors need extra security

French doors, also known as double doors, are a beautiful addition to any home, offering elegance, natural light, and easy access to outdoor spaces. But while they enhance your home’s aesthetic, French doors can present a security risk if not properly protected. Here’s why:



  • Large glass panels – the most obvious weak point is the large expanse of glass. A burglar can potentially shatter a pane to reach in and unlock the door from the inside, or simply create a large enough opening to enter.

  • The central meeting point – unlike a single solid door, French doors have two panels that meet in the middle. If this central seam is not properly secured, it can be a weak point that can be pried or kicked open.

  • Exposed hinges – if the French doors open outward, their hinges are on the outside of the house. An intruder with the right tools could potentially remove the hinge pins to lift the door off its frame.

  • Older or Poorly Installed Doors – older French doors or those that were not installed correctly may have loose-fitting hardware, weak frames, or gaps that a burglar can exploit.


A robust security door acts as a physical barrier, deterring intruders and providing peace of mind. By investing in a high-quality security door for your French doors, you can enjoy elegance and charm without compromising your home’s safety.

FAQ's

Common questions about purchasing and installing a security door for your French doors.

The best option is a custom-made, hinged security screen door with high-tensile stainless steel mesh and a multi-point locking system. Crimsafe doors are ideal because they combine strength, durability, and professional installation:

  • High-tensile mesh: Made from woven stainless steel, it resists cutting, shearing, and forceful impact, making it extremely difficult for intruders to break through.
  • Custom fit & professional installation: French doors vary in size and shape. A custom-made door ensures a snug, gap-free fit, while expert installation guarantees structural integrity and proper lock alignment.
  • Multi-point locks: Locks engage at the top, bottom, and middle of the door, eliminating the central weak point where the two doors meet and making it nearly impossible to pry open.
  • Strong frame & hardware: The mesh is securely clamped into an aluminum frame using Crimsafe’s patented Screw-Clamp™ technology, preventing it from being removed or tampered with.

Crimsafe doors meet Australian Standards, providing maximum security while maintaining the elegance, ventilation, and visibility of your French doors.

Yes, Crimsafe has designed security doors specifically designed to address the specific vulnerabilities of French doors, while maintaining aesthetic appeal. Here’s how their system works and what makes it a popular choice:

  • Triple Locking Mechanism: prevents the doors from being pried open and is a massive deterrent to burglars.
  • Bolted for Strength: the system is designed with two doors: one is bolted top and bottom to provide a rigid, secure anchor. The other door then locks into it with the multi-point mechanism, creating a single, formidable barrier.
  • Patented Screw-Clamp™ Technology: designed to withstand incredible force and prevents the mesh from being kicked out of the frame.
  • Custom-Made for a Perfect Fit: crucial for a secure fit, as it eliminates any gaps that an intruder could exploit.

Crimsafe’s French door security solution is a complete system designed to turn a potential weak point into an incredibly strong and stylish entry. It allows you to use your French doors as they were intended—to enjoy the outdoors and fresh air—while providing a high level of protection.

A multi-point lock secures a security door at several points along the frame—typically the top, middle, and bottom—rather than just a single central lock. When you turn the key or lift the handle, all locking points engage simultaneously, making it extremely difficult for intruders to force entry. A burglar can’t simply pry the door open at the single weak point; they would have to defeat multiple locks at once.

This distributed locking system also strengthens the door, prevents warping or sagging over time, and improves insulation against drafts, noise, and weather.

Crimsafe security doors are the ideal solution, featuring Lockwood 8654 locks with three-point stainless steel hook latches and anti-bump technology. They combine enhanced security, durability, and peace of mind. Find out more about our Crimsafe security doors.
