Transparent burglar bars have changed the way South Africans think about residential security.
In 2004, forward-thinking pioneers in the South African security industry began experimenting with polycarbonate thermoplastic as a burglar bar solution. One of the earliest innovators, Martin Nauta, a mechanical engineer, recognised the potential of using crystal-clear polycarbonate strips instead of steel.
Homeowners wanted protection — but without blocking natural light, architectural lines, and scenic views. This demand led to the development of clear burglar bars manufactured from high-impact polycarbonate. At the time, this was a radical idea because steel had always been the go-to for security bars.
Steel came with compromises:
- Rust over time
- Heavy visual obstruction
- Reduced natural light
- Estate design restrictions
The concept of “invisible” or transparent burglar bars introduced a new category of security. Brands such as Multisafe were among the early adopters, helping to bring polycarbonate security solutions into the South African residential market. Their introduction of clear security bars, better known as ClearBars®, helped create awareness and acceptance of this modern alternative. This period marked the birth of what is now a well-established industry.
Polycarbonate was not a decorative material, because it was already widely used in:
- Riot shields
- Bullet-resistant glazing
- Aircraft windows
- Machine guards
Unlike Perspex (acrylic), polycarbonate:
- Absorbs impact instead of shattering
- Can be drilled and anchored securely
- Has higher heat resistance
- Offers long-term durability
This made it ideal for transparent burglar bars designed for real security — not just appearance. The introduction of UV-treated polycarbonate strips allowed homeowners to maintain crystal-clear views while gaining strong impact resistance.
As awareness grew, transparent burglar bars gained popularity across:
- Johannesburg
- Cape Town
- Pretoria
- Durban
Security estates and complexes nationwide
Security estates increasingly preferred clear burglar bars because they:
- Maintain architectural uniformity
- Preserve property value
- Allow natural light
- Avoid the “prison-bar” aesthetic
The industry evolved from niche innovation to a mainstream security solution.
Today, transparent burglar bars are widely accepted as a modern alternative to traditional steel bars.
High-quality polycarbonate burglar bars, as made available by ClearBars®, are:
- UV-treated to resist yellowing
- Professionally installed for structural integrity
- Accepted by many insurance providers
- Suitable for aluminium, wooden and uPVC windows
What began as an experimental idea in the early 2000s has become a recognised category in South African home security.
