When it comes to home security, your garden entrance is just as important as your front door. Whether you are looking for a sliding patio door with a lock for a new installation or wanting to upgrade your current sliding door security, understanding your options is the first step toward peace of mind.
A glass sliding door with a lock offers a perfect blend of natural light and safety, but not all locking mechanisms are created equal. In this guide, we’ll break down the best ways to protect your home.
Understanding Patio Door Lock Types
Standard latches are a start, but for true security, you should consider a variety of patio door lock types. Depending on your door style, you might encounter:
- Multi-Point Locks: These engage at several points along the frame, making it incredibly difficult for intruders to jemmy the door open.
- Patio Door Slide Locks: Often mounted at the top or bottom of the door, a patio door slider lock acts as a secondary defence.
- Slide Bolt Locks: A heavy-duty slide bolt lock provides a physical barrier that prevents the door from being lifted off its tracks.
- Sliding Glass Door Lock Bars: These are adjustable bars that sit in the track, physically stopping the door from sliding open even if the primary lock is compromised.
How to Secure a Patio Sliding Door
If you’re wondering how to secure a patio sliding door effectively, it’s all about layers. A lockable sliding glass door is most effective when combined with high-quality hardware.
Replacing basic door handles for sliding patio doors with ergonomic, reinforced handles can prevent forced entry. Furthermore, choosing a sliding patio door lock with a key ensures that even if a window is broken, the door cannot be easily opened from the inside to move large items out of the home.
Specialised Solutions: From Rollers to Wardrobes
Security isn’t just for the backyard. Different doors require different hardware:
- Roller door locks: Essential for garages or commercial shutters to ensure the mechanism is pinned securely.
- Lockable sliding wardrobe doors: Perfect for home offices or shared living spaces where you want to keep valuables or sensitive documents private.
