Burglar bars have been standard home security in South Africa for decades, but a growing number of homeowners are questioning whether bolting steel across every window is still the best approach. The cost runs to R12,000 or more for a typical home. The bars block ventilation, reduce natural light and create a fire safety risk. And the prison-like aesthetic can reduce kerb appeal rather than enhance it. A new category of window security — locks that hold windows open at a fixed, secure gap — is changing how people think about the trade-off between security and liveability.
The Real Cost of Burglar Bars
In South Africa, standard fixed steel burglar bars cost between R770 and R1,320 per square metre installed. A standard bedroom window costs R1,800 to R2,400. A large lounge window can reach R4,500 to R6,000. For a three-bedroom house with eight to ten windows, the total runs between R12,000 and R24,000 — before considering removable, transparent or decorative options that cost considerably more.
Professional installation is required. The work involves welding, drilling into masonry or window frames, and custom fabrication for each opening. It typically takes a full day to complete an average home.
By comparison, a LockLatch® window lock costs a fraction of one window’s worth of bars. Installation takes 15 minutes per window with a household drill — four screw or rivet holes and it is done. No tradesman required.
The Ventilation Problem Most Homeowners Overlook
Burglar bars secure a closed window. But they do nothing to address the most common entry method used in opportunistic burglaries — an open or unlocked window. Homeowners face a choice: close the window for security and lose airflow, or open it for ventilation and accept the risk.
LockLatch® eliminates that trade-off. It locks any window or door in the open position at an adjustable gap of 9 to 17 centimetres — wide enough for full airflow, too narrow for an intruder to pass through. The window is secured with a lockable pin that cannot be released from outside. It delivers secure ventilation without sacrificing security.
Fire Safety: A Risk That Goes Unmentioned
Data from the United States National Fire Protection Association shows that approximately 25 civilians are injured or killed annually in fires where escape is blocked by window bars or security gates. The actual figure is likely higher due to underreporting. Most jurisdictions now require quick-release mechanisms on barred sleeping room windows, but the majority of installed bars do not comply.
A window secured with a LockLatch® opens fully and instantly when the pin is released from inside. In an emergency, every second matters.
What Happens to Property Value
In high-crime areas, buyers may expect security bars and view them as necessary. But in suburban and urban markets, bars signal danger. Multiple estate agents have noted that visible bars can reduce kerb appeal and make prospective buyers uncomfortable. The aesthetic of a barred home is, by any measure, institutional rather than welcoming.
LockLatch® is virtually invisible once installed. It sits flush against the window frame and does not alter the appearance of the property from inside or outside.
How the Two Options Compare
Burglar bars are a physical barrier over a closed window. They prevent forced entry through glass but do not address an open window. They require professional installation, ongoing maintenance to prevent rust and corrosion, and they permanently alter the look of a home.
LockLatch® is a different approach. It restricts the opening distance of a window or door to a secure gap, preventing entry while allowing full ventilation. It is made from C304 rust-resistant stainless steel with a lifetime guarantee and requires only minimal maintenance. It fits any window or door type including aluminium, uPVC, timber and steel.
Which Option Is Right for Your Home
For high-risk ground-floor windows in areas with frequent forced-entry burglaries, bars remain effective. But for the majority of homes — where the risk is an open window left unattended, where ventilation and natural light matter, where aesthetics count and where the budget does not stretch to R20,000 — a window lock that secures the opening is the more practical solution.
