European Windows Security Standards: Basic, WK1, and WK2
Most of us think about windows in terms of looks — the style, the view, the light — but very few people think about how safe they actually are. This is where European window security standards such as Basic, WK1, and WK2 become important.
Your windows might be letting in the sun just fine, but if they’re easy to open from the outside, they’re not doing much to keep your home safe. That’s where European security standards come in. You’ve probably seen terms like Basic, WK1, and WK2 floating around and wondered what they really mean. Don’t worry — you’re not alone. Let’s break it down in plain, friendly language, so you know exactly what each level of protection means for your home.
Many modern European tilt and turn windows are designed specifically to meet these standards while offering superior functionality and design.
Why European Window Security Standards Matter
Here’s the deal: windows are your home’s first line of defense. Sure, locks on doors matter, but if a burglar can get in through a window in seconds, all the fancy locks in the world won’t help.
European security standards were developed to make sure windows can actually hold up against someone trying to break in. When a window is labeled WK1 or WK2, that means it has been tested under real-world conditions with different tools and methods. Basically, it’s a promise that your windows aren’t just decorative — they’re keeping you and your family safe.
At Hawkeye Windows, we not only care about security but also care about looks and energy efficiency. Because let’s be honest, a beautiful window is good and all… but a secure one? That’s priceless.
Windows Basic Security: Your Everyday Peace of Mind
Basic security represents the minimum level found in modern windows and serves mainly as a comparison point for higher security classes.
These windows come with normal locks and handles and are perfect for rooms that aren’t super accessible or for homes in low-risk areas. They won’t stop someone with time and tools, but they do make it a lot harder for someone to just “push it open.”
Think of basic security as the first layer of protection — like a friendly neighbor who keeps an eye on your house. It’s simple, functional, and gives you peace of mind without going overboard.
WK1: A Step Up
Next up, we have WK1. This is short for Resistance Class 1.
These windows are made to withstand break-in attempts with simple tools like screwdrivers or pliers. They have reinforced frames, strong locks, and sturdy hinges designed to slow anyone down. And let’s be real — that’s often enough to make a burglar say, “Nah, not worth it,” and move on.
WK1 is ideal if your windows are easily reachable — like ground-floor windows — or if you just want a bit more peace of mind without spending a fortune. Most homeowners find it’s the perfect balance of safety and practicality.
However, WK1 is typically recommended only for moderately accessible windows and is not intended for higher-risk locations.
WK2: When You Want Top-notch Security
Now, if you’re someone who wants a high level of protection, WK2 is your answer.
WK2 (Resistance Class 2 under EN 1627) is one of the most commonly recommended security levels for European windows.
These windows are tested against heavier tools like crowbars and hammers. They’re built with multi-point locks, reinforced frames, and really strong hardware. Basically, breaking in is going to take serious time — and no burglar wants to spend that long at your house.
This level of protection is commonly found in windows with WK2 security, making them ideal for ground-floor installations and high-risk locations.
WK2 windows are perfect for high-risk areas, ground-floor windows in busy neighborhoods, or anytime you just want extra reassurance. It’s like having a security guard built into your window.
For this reason, WK2 is the security level most commonly specified in European window systems supplied by Hawkeye.
How They Test These Windows
Curious how they figure out if a window is WK1 or WK2?
Testing is performed according to standardized EN 1627 procedures using defined tool sets and attack durations.
For a broader comparison between European and American approaches to window testing, see our detailed guide on ASTM vs EN 1627 standards.
They basically try to break it using a set of tools for a certain amount of time. If the window is able to withstand that, it earns the certification:
- WK1: This resists simple tools like screwdrivers and pliers.
- WK2: Made to resist more aggressive tools like crowbars and hammers.
So whenever you see a certification, it’s not just marketing — it’s a real-world guarantee.
How Do You Choose the Right Security Level for Your Home
Here’s an easy way to figure it out:
- Upper floors or low-risk places: Basic may be sufficient as a baseline level of protection.
- Average residential areas or ground-floor rooms: WK1 provides an extra layer of safety.
- High-risk areas, easily accessible windows, or just absolute peace of mind: WK2 is the way to go.
All these options are part of European window systems tested under EN 1627, where every component contributes to overall performance.
And remember, it’s not just the type of glass that matters. High-quality window and door hardware—including locks, handles, and hinges—also plays a critical role in overall window security. At Hawkeye, we make sure that every component meets the correct standard and is supported by proper installation, because even the best window system can underperform if it is not installed correctly.
Extra Tips for Making Your Windows Even Safer
- Keep locks and handles in good condition.
- Consider adding a security screen for extra resistance.
- Add window sensors or alarms, especially on ground-floor windows.
- Make sure doors are just as secure as your windows.
While these measures can help, the foundation of window security always starts with certified hardware, glazing, and proper installation.
