The most important facts in brief

  • Burglar-proof windows are anchored several times at different points in the masonry via their frames. In addition, they are usually equipped with lockable handles as well as burglar-resistant or partially breakthrough-resistant glazing.
  • You can install burglar-proof windows from scratch or have them retrofitted. New windows are usually installed by a specialist company, which guarantees a professional result. On the other hand, this installation involves a lot of effort and high costs.
  • There are different resistance classes which are defined in the European DIN EN 1627 test standard. The higher the resistance class, the better the burglary protection.

Burglar-proof windows: the ranking

1st place: ABUS lockable window handle FG200

With the ABUS lockable window handles, you can retrofit existing windows, so that you achieve a higher level of protection against burglary. These window handles are childproof, which means that they are equipped with a pressure cylinder.

They can be easily installed in a few minutes. You also need a single key for all your windows, which makes daily use effortless. The lockable handles fit all types of windows: windows, balcony or patio doors made of aluminium, wood or plastic.

2nd place: Thustar alarm system

The Thustar alarm system is a wireless alarm system. It can be mounted on the windows with a magnetic safe detector, so that the perpetrator is detected when trying to open the windows.

This wireless alarm system supports six preset alarm numbers and two help SMS numbers. In the event of an alarm, the device dials the preset number and automatically sends a message.

The built-in emergency battery can continue working for about six to eight hours in the event of a power failure. This system also includes a configurable wired siren of up to 110 dB volume to deter potential intruders.

3rd place: ABUS automatic hinge side securing

The FAS 97 automatic hinge side securing system from ABUS is suitable for inward opening windows and French doors.

The window lock must be activated by operating the frame rail before tilting the window. The window is locked automatically during closing.

This is an effective protection against levering. The advantage is also that the automatic hinge side lock can be operated without a key.

Advisor: Questions that you should deal with before you install burglar-proof windows

How do burglar-proof windows work?

A burglary protection system is usually intended to withstand the attack of burglars for a few minutes. In most cases, this time is sufficient either to notice the perpetrator or to demotivate him.

Burglar-proof windows cannot be visually distinguished from other windows.

The difference lies in the fact that the frames are anchored several times at different points in the masonry. The internal fittings contain mushroom head pins that provide good resistance to lifting.

In addition, these windows are usually equipped with lockable handles and burglar-resistant or partially breakthrough-resistant glazing.

Where can I buy burglar-proof windows?

Burglar-proof windows are usually installed by a specialist company. Often the decision for burglar-resistant windows is made during the construction of the house.
This is more practical because the wall can be made to measure of the windows.
The specialist companies usually also offer their services online on their websites. If you want to retrofit the burglar protection without a company, you can buy various window locks on the Internet and install them yourself.
According to our research, most of the window locks for retrofitting burglar-proof windows are sold via these online shops:

Amazon.com
Bauhaus.info
Obi.de
Hornbach.de

How much do burglar-proof windows cost?

There is a wide price range between the different burglar-proof windows. Nevertheless, each company makes customer-specific offers depending on the conditions in the house.
Depending on the type of windows or doors and the desired security, the price varies greatly.

A new plastic window with burglary protection usually costs from 300 to 400 euros. However, there is still a lot of room for improvement. The corresponding equipment can also easily cost 1,000 euros and more.

What classes of burglar-proof windows are there?

Basically, the different resistance classes indicate how long a product can withstand the burglary attempt of a certain type of offender. The higher the class, the better the burglary protection.
The police recommend products that are at least class RC2.

Always close all windows and doors when you leave the house. Even tilted windows should be locked.

The resistance classes of burglar-proof windows are now marked with the abbreviation RC for Resistance Class (formerly WK). This results from the DIN EN 1627 test standard.

There are various European and national standards for burglary resistance. These regulate requirements, test methods and classification of resistance.

The European standards series EN 1627-1630 defines requirements and classifications and describes the static and dynamic loads. It specifies the possible manual break-in attempts.

The standard “DIN EN 1627: Test standard for windows, doors, curtain walls, lattice elements, closures” defines resistance classes, resistance times (time during which the product withstands a burglary), types of offender and the modus operandi.

What alternatives are there to burglar-proof windows?

Burglaries are a big issue. Just a few easy to follow tips can help prevent them. Burglars often profit from the carelessness of the house owner.

There are various products and retrofits that you can consider as alternatives to burglar-proof windows.

Grille: Especially for windows on the ground floor or in the basement, a window grille is a common and cost-effective solution.

Tape side protection: The tapes of windows are often a weak point for burglaries. If not additionally secured, they can be levered inwards. Lateral hinge securing, also known as back gripping hooks and positive locking, is intended to minimise this risk.

Lockable window handles: Lockable window handles are a simple solution not only for burglary protection but also for child protection.

Anti-burglary film: A film is a tested solution for the subsequent coating of window glass to protect against break-ins.

Glass breakage detector: The glass breakage detector gives an acoustic signal if the window has been damaged.

Decision: What types of burglar-proof windows are there and which one is right for you?

If you want to get burglar-proof windows, there are two alternatives you can choose between:

  • You can buy brand new burglar-proof windows or
  • retrofit your existing windows.

You can have new burglar-proof windows installed by a professional company. This ensures the best result when it comes to professional installation. Moreover, the product in this case is tailor-made for your house.

On the other hand, you can also increase the security of your windows with much less effort if you opt for an easier retrofit. This can also be done by a specialist company.

What distinguishes burglar-proof windows and what are their advantages and disadvantages?

A correctly installed window offers increased protection against burglary, as unwanted guests are not only prevented from breaking the window, but also from drilling the window handle.

You can order such windows from a specialist company that will install the appropriate anti-burglary elements in your house individually.

It is even easier if you think of the security measures already during the construction of the house, so that the walls and frames can also be built to fit.

Advantages

Increased security
Technical advice
Suitable size

Disadvantages

Costly
More effort
Expensive, if damaged

However, installation is more complicated than retrofitting. You have to get completely new burglar-proof windows and often also convert the walls/floor (for example with patio doors).

However, it is true that this variant often offers a higher level of general safety than retrofitting individual parts to existing windows. As a rule, specialist companies use DIN-certified products that guarantee a certain level of security.

What distinguishes the retrofitting of burglar-proof windows and what are their advantages and disadvantages?

To protect your home from burglary, it is not always necessary to equip the house with completely new windows. You can also do this by retrofitting existing windows with burglar-proof elements.

This involves dismantling the existing parts of the window and installing new burglar-resistant variants. Which elements can be replaced?

  • Lockable handles
  • Verglasung
  • Burglar-resistant window fittings / mushroom head locking
  • Window catch
  • Window grille
  • Safety film

Windows are more often used as an entrance for burglars than front doors or patio doors. Therefore you should not do without burglar-proof windows!

The installation of burglar-proof windows, however, involves a great deal of effort and relatively high costs. Therefore, retrofitting is a popular choice for window burglary protection.

Advantages

Less effort
Cheaper
Self-assembly

Disadvantages

Lower security
Products often not DIN-certified
Existing windows not always suitable

In case of a retrofit, your windows do not have to be replaced completely, you only have to retrofit your existing windows.

With a correct installation, you can obtain the same level of window security as when installing a completely new burglar-proof window.

Purchase criteria: You can compare and evaluate burglar-proof windows based on these factors

In the following we would like to show you which factors you can use to compare and evaluate burglar-proof windows. This will make it easier for you to decide whether a particular burglar-proof window is suitable for you or not.

In summary, these are:

  • Resistance class (RC)
  • Verglasung
  • Material of the frame

Resistance class (RC)

When buying windows, the customer can choose between different security levels for the fittings. The higher the resistance class, the better the burglar-resistant effect of the hardware.

The resistance classes are marked with RC (Resistance Classes). There are six levels, which are defined in the DIN EN 1627 test standard. These classes explain how long a product can withstand the burglary attempt of a certain type of offender.

The higher the class, the better the burglary protection. The police recommend using products that are at least class RC2.

You can find out more about resistance classes in the guide section under “What classes of burglar-proof windows are there?

Verglasung

Burglar-resistant glazing is characterised by the fact that, in comparison with ordinary clear glass, it stops glass breakage by external impact as long as possible.

The Association of Non-Life Insurers (VdS), in turn, implements a relative gradation of the breakthrough and penetration inhibition:

To give you a better idea, we have selected a suitable video about glazing for burglar-proof windows:

Material of the frame

Usually you can choose between these materials when it comes to the window frame:

  • Plastic windows: These frames mainly provide excellent thermal insulation and durability. Thanks to the easy workability of PVC, these models can be made with profiles tailored to your needs.
  • PVC-aluminium windows: The PVC-aluminium windows provide both thermal insulation and reliable protection against weathering and break-in attempts.
  • Wooden windows: Wooden window frames contribute greatly to a warm and homely atmosphere in your home. Most of the time you have the choice between oak, pine, meranti, spruce, larch and eucalyptus. With burglar-resistant glazing, these windows offer optimal sound insulation and protection against burglary.
  • Wood-aluminium windows: This combination offers the respective advantages of the two building materials. It is energy-saving and safe. From the outside, an aluminium shell acts and protects, while the wood provides thermal insulation from the inside.

Trivia: Worth knowing facts about burglar-proof windows

Collapse statistics in Germany

For the first time in about two decades, the number of burglaries has fallen below the 100,000 mark. This is according to the nationwide police crime statistics (PKS) for 2018.

Source: Police crime statistics (PKS)

In 2018, 97,504 break-ins were registered. This is a reduction of 16.3 percent compared to 2017, with burglars causing losses of around 260 million euros.

Attempted burglaries are also classified as “domestic burglary”. This means that even if the perpetrator did not make it into the apartment or house, it is still considered an attempt. And whether it stays that way depends primarily on how well the house is secured.
