Is uPVC Windows Safe in South Africa? Here’s the Truth.

The Ultimate Guide to uPVC Window Security

Keeping your home safe starts with secure uPVC doors and windows, designed for durability and protection.

Weak, outdated windows are often the first point of entry for intruders. Modern window technology makes high-quality uPVC windows a top choice for homeowners who want style and security.

At uPVC.co.za, security is at the heart of our window designs. Our uPVC doors and windows do more than enhance your home’s look—they protect your family and valuables. But how secure are they? Let’s take a closer look at the security features that make them a top choice for South African homes.

Why Are Windows a Target for Intruders?

Intruders often look for the weakest point of entry in a home, and windows are typically at the top of their list. Why?

Easy to Break or Force Open – Outdated windows with weak security locks are an easy target.
Out of Sight, Out of Mind – Back windows or bathroom windows are often in less visible areas.
Quick Entry/Exit – Windows provide fast access for intruders to enter and escape.

This is why investing in secure, modern polyvinyl chloride (uPVC) windows is essential for home safety.

Are uPVC Windows Secure?

The short answer is yes! But not all uPVC doors and windows offer the same level of security.

The level of security depends on the features, multi-point locking mechanism, and glazing options. At uPVC.co.za, we provide extra protection with laminated glass, double or triple glazing, and impact-resistant frames.

Here’s what makes uPVC windows from uPVC.co.za a superior choice for home security:

1. Multi-Point Locking System

One of the biggest security advantages of high-quality uPVC windows is the multi-point locking mechanism. Instead of relying on a single latch, this system locks the window at multiple points along the frame. This adds an extra layer of security, making it extremely difficult for intruders to force the window open.

How it works:

When you turn the handle, multiple locking points (top, bottom, and sides) engage.
Even if an intruder tries to pry the window open at one point, the other locking points stay secure.

Our Ranges:
Ecoline– Basic security with single latch.
Ultraline – Advanced multi-point locking mechanisms for superior security.

2. Shatter-Resistant Glass

Another critical component of uPVC door and window security is the type of glass used. Intruders can smash weak glass in seconds and break into your home.

That’s why our uPVC ranges offer double or triple glazed glass options with improved resistance to break.

How it works:

Double glazing adds a second layer of glass, making it harder to break. If the first pane breaks, the second pane stays intact.
Laminated glass provides additional resistance to break, making it even harder for intruders to gain entry.

Our Ranges:

Econoline – Single glazing (standard) but double glazing is available in this range.
Ultraline – Double or triple glazed options available for maximum strength and security.

Pro Tip: If security is a top priority, choose laminated glass with double or triple glazed options.

How Strong is Laminted Glass? 

Here’s how different types of laminated glass or shatter resistant glass compare in resistance to break:

Normal Strength Glass (6.38mm, 3 Blows): Suitable for basic security, broken in 3 hammer blows.

High Penetration Resistance Glass (6.76mm, 8 Blows): Recommended for mid-level security and requires 8 hammer blows to break.

High Impact Glass (7.52mm, 24 Blows): Adds an extra layer of security, making it nearly impossible to break.

Pro Tip: For peace of mind, choose High Impact Glass for the strongest resistance to break-ins.

3. Reinforced uPVC Frames

A secure window frame is just as important as security locks and shatter-resistant glass. Older wooden frames rot, and metal frames rust, but uPVC frames stay strong, weatherproof, and impact-resistant.

uPVC frames use custom profiles. This method helps seal them well. It prevents leaks and drafts. This is different from wood and aluminum frames. You can’t install a uPVC window in a wooden or aluminium frame because they use different profiles and systems.

Why it matters:

uPVC does not rot, rust, or weaken over time.
Reinforced polyvinyl chloride (uPVC) frames are more resistant to break, making them harder to force open. Our premium ranges have thicker profiles, offering enhanced security against intruders.

Our Ranges:

All ranges (Ecoline and Ultraline) have durable, reinforced polyvinyl chloride (uPVC) frames. At uPVC.co.za, we make Ecoline using Rehau’s Pureline range and Ultraline from the Ecotech range.

💡 Pro Tip: Choose Ultraline for the strongest, most impact-resistant frames.

4. Anti-Lift Technology

Standard sliding windows can be vulnerable to “lifting” attacks, where intruders lift the window off its track. But not with uPVC.co.za sliding windows. Our sliding windows have anti-lift technology. This prevents intruders from lifting the window off the track from outside.

How it works:

The sliding track includes a special anti-lift safety feature. Even if someone tries to lift the window from the outside, it stays locked in position.

💡 Pro Tip: If you’re considering sliding windows, make sure they have anti-lift protection. Our Ultraline range offer enhanced security with this feature.

5. Child-Safe Locking Systems

If you have children at home, safety features are a key concern. uPVC.co.za windows offer optional child-safety window locks to stop children from opening windows too wide while still allowing ventilation.

How it works:

The window can only open to a limited position for safe ventilation. Parents can unlock it for a full swing-open position when needed.

Our Ranges:

Available as an optional extra for all uPVC door and window ranges.
