When it comes to home security, choosing the right burglar bars is one of the most important decisions a homeowner can make. Whether you are securing a family home, a rental property, a holiday house, or an estate residence, the type of burglar bars you choose will directly impact your safety, comfort, and the look of your home.
With so many options available — from traditional steel bars to modern clear polycarbonate solutions — knowing what to select can feel overwhelming. The right burglar bars should offer a balance of strength, aesthetics, and long-term durability, while fitting the style and security needs of your home.
This guide breaks down the key differences to help you make an informed, confident decision.
1. Material Matters
Steel Burglar Bars
Traditional steel bars remain a common choice for many households in South Africa. They are strong and widely available, but they come with several limitations:
- They can rust or corrode, especially in coastal regions, high maintenance.
- They may make a home feel closed-in or prison-like
- They reduce natural light
- They are visually intrusive and can devalue modern aesthetics
Modern clear burglar bars offer a clean, elegant security solution — especially for homes with scenic views, large windows, or architectural features you want to preserve.
Clear Polycarbonate Burglar Bars
However, not all polycarbonate bars are created equal.
Suppliers to retail hardware stores are typically cheaper polycarbonate that use regrind in the production line to curb expenses:
- Yellow in the sun
- Become brittle over time
- Warp or weaken within a few years
This is why the quality of the polycarbonate is critical.
2. EXOLON® vs Generic Polycarbonate
At SheerGuard, our Clear Burglar Bars are manufactured from EXOLON®/Makrolon® polycarbonate — the same advanced material used in aircraft windows and high-security applications.
This premium material ensures:
- Exceptional impact resistance
- Near 100% optical clarity
- UV stability
- Outstanding performance in harsh sunlight or coastal weather
Very few clear burglar bars on the market combine this high-grade polycarbonate with a purpose-designed installation system, and this is what sets SheerGuard apart in the South African security market.
3. The Importance of Professional Installation
Even the strongest material is only as secure as its installation method.
DIY clear bars from retail stores are typically fitted using:
- Aluminium pop rivets which are easy to drill out
- Silicone
- Adhesive glue
- Basic screws
These fixes can be removed quickly and are not insurance-compliant.
SheerGuard Clear Burglar Bars are installed using stainless-steel, tamper-proof compression rivets, providing:
- Maximum holding strength
- No weak points around the frame
- Proper spacing and alignment
- Full compliance with insurance standards
- Cannot be drilled out
This precision installation is essential for real home and business security.
4. Aesthetic Impact
Today’s homeowners want security without compromising on their home’s design.
- Steel burglar bars can darken a room and significantly impact the aesthetic of your home
- Clear burglar bars provide invisible, modern protection while maintaining natural light and beautiful views
If you are upgrading, renovating, or preparing a home for rental or sale, clear polycarbonate bars offer the perfect balance of style and safety.
5. Longevity & Maintenance
Lower-quality clear burglar bars may look acceptable at first, but they degrade quickly.
EXOLON® polycarbonate:
- Stays optically clear for life
- Self-extinguishing properties
- Does not weaken in UV exposure
- Requires minimal maintenance
SheerGuard provides a Lifetime UV Warranty, ensuring long-term value and peace of mind.
6. Cost vs Value
While DIY burglar bars may appear cheaper upfront, they often cost more over time due to:
- Replacements
- Poor durability
- Premature failure
- Lack of insurance compliance
- Reduced property value
- No guarantee
A professionally installed, premium solution offers far better value in the long run — and significantly better protection.
Conclusion: Security without compromise
Choosing the right burglar bars is about more than simply securing a window — it’s about protecting your home with a solution that is strong, durable, aesthetically pleasing, and trusted.
