Polycarbonate Explained

Not All Clear Bars Are Created Equal

At first glance, all transparent burglar bars look identical. But beneath the surface, there is a massive difference between cheap, amateur plastics and premium, engineered security structures.

To understand why HomeGuard Security barriers deliver unparalleled protection, you need to understand the science behind the material we use, and why we refuse to compromise on quality.

What is Polycarbonate?

Polycarbonate is an advanced, naturally transparent amorphous thermoplastic. It is an engineering-grade material utilized when absolute optical clarity must be paired with extreme, heavy-duty impact resistance.

To put its raw strength into perspective: high-quality polycarbonate has an impact strength 250 times greater than glass and 30 times greater than acrylic. It is the exact shatterproof material trusted worldwide for:

  • Police riot shields and tactical protective gear

  • Bullet-resistant security enclosures

  • High-altitude airplane windows

The Industry Secret: The Danger of Cheap Imitations

Because transparent bars have become highly sought after by architects and premium property developers, the market has been flooded with low-cost, amateur alternatives. Many generic installers use low-grade plastics or non-regulated, recycled polycarbonates to cut down costs.

In a harsh climate like South Africa's, these inferior materials fail rapidly. Under intense UV radiation, cheap plastics turn brittle, yellow, and lose their structural integrity within months—allowing them to be easily cracked, broken, or kicked out by an intruder.

The HomeGuard Standard: Powered by View Protect

We believe that security is an absolute commitment. That is why HomeGuard Security operates as a premier certified installer in exclusive partnership with ViewProtect, utilizing only the absolute highest tier of internationally regulated, ISO-certified polycarbonate sheet materials:

1. LEXAN™ Polycarbonate (The Gold Standard)

Manufactured by SABIC from 100% virgin raw materials, LEXAN™ is globally recognized as the most robust polycarbonate available.

  • Dual-Sided UV Protection: Our LEXAN™ bars feature advanced UV-stabilized coating on both sides. It is scientifically proven to endure intense sunlight and weather extremes without losing its strength.

  • Flawless Optical Clarity: It looks indistinguishable from premium glass, ensuring your property maintains its architectural aesthetic.

  • 10-Year Written Warranty: HomeGuard proudly backs our LEXAN™ installations with a limited 10-year factory warranty against discoloration.

2. NAXEL™ Polycarbonate (The Performance Alternative)

For projects requiring an exceptional cost-to-performance ratio without sacrificing raw security, we offer NAXEL™ polycarbonate.

  • Reliable Security: It retains the signature high impact resistance and heat deflection properties of virgin polycarbonate.

  • Engineered Value: Optimized to deliver elite physical defense at a highly competitive investment level for large-scale developments.

The Ultimate Evolution: From Passive Material to Smart Sensor

Even the strongest raw material can eventually be compromised if a criminal is given enough time in the dark. That is where the synergy between HomeGuard's master installation and View Protect's engineering completely changes the game.

We don't just fix plastic to your windows. We take the world's strongest polycarbonate and integrate internationally patented Smart Bar Technology. By weaving an invisible, in-series electrical pulse wire through the grooves of these ultra-tough bars, HomeGuard transforms a physically unbreakable shield into a 24/7 active alarm sensor.

If it is cut, melted, or tampered with, the wire breaks and triggers your alarm instantly—long before an intruder ever steps foot inside your home.

Precision Touches 

Every single bar prepared for a HomeGuard installation features mechanically rounded edges straight from the factory. This ensures that while the system stands as a brutal physical barrier against criminals, it remains completely safe to the touch for your family, your children, and your pets.
