Guide: Questions you should ask yourself before buying lockable window handles
What do lockable window handles do?
Lockable window handles are mainly used for security against danger, as they can be used to lock windows securely.
With the corresponding key, they can be locked like an outside door.
This distinguishes them from conventional window handles, as these generally do not have a lock to lock them. This makes them particularly useful as burglar or child protection.
So if you are thinking about protecting your house or your children from danger, lockable window handles are a very useful tool.
Some handles even have a built-in alarm function that emits an acoustic signal in the event of a possible burglary, for example, to scare away potential burglars from their plans.
How useful are lockable window handles?
If you live in an area where there are a lot of burglaries, you will be better protected with a lockable window handle.
These can also have a built-in alarm function. In these places, it makes most sense to install lockable window handles:
- Ground floor windows
- Balcony doors
- Patio doors
It is also important to install burglar protection on front doors.
How secure are lockable window handles?
Note: It is important to realise that lockable window handles cannot guarantee absolute security against burglary.
They can mainly be used to reduce the risk, but not to completely exclude it. This applies mainly to burglaries. This is why they are considered more of an anti-burglary instrument.
Why? Windows could still be smashed, but most burglars want to cause as little commotion as possible.
Loud noises would immediately be heard by neighbours. The burglary attempt would immediately fail.
That is why a so-called glass penetration is usually used for burglaries.
In this process, only a small area of the glass pane near the window handle is smashed in order to get to the window handle.
Many windows have been opened this way. A locked handle would prevent this.
On the other hand, they are excellent child protection, provided that children do not get their hands on the key for the lock.
Especially if you live on a higher floor than the ground floor.
Why? If left unattended, children could open the window and, in the worst case, fall out of it. The resulting consequences could be devastating.
The most important thing to remember is that you should keep the key safe. So that the children cannot find it by accident.
What should you look for in lockable window handles?
In addition to lockable window handles, there are two other tools that further increase window security.
Mushroom head pins and window security film. These are also two other efficient tools that should be retrofitted to further optimise security.
A normal window does not normally have a resistance class. With these additional measures besides the lockable window handles, you can increase your security even further, to the standard of class RC2.
Further resistance classes are listed below for overview purposes.
The number of minutes is a guideline of how long a burglar needs on average at the respective resistance class to open the window from the outside.
A resistance class of a window indicates how well it is secured on the lock and hinge side. RC stands for resistance class.
The higher the number, the more secure the class is against burglars. The classification of resistance classes has been Europeanised since 2011.
When you search for windows online, you can usually find the RC value in the article description.
In the following video, which was produced by the company Aldra, you can watch an example of an attempt to lever open an RC2 window.
It shows how difficult it is to crack a class 2 security window:
How much do lockable window handles cost?
The following comparison shows how the costs differ depending on the material of the window handle.
Lockable window handles are often offered in sets, therefore the individual price was taken into account here in order to better compare the two materials.
|Aluminium||approx. 8-40 €|
|Stainless steel||approx. 15-120 €|
For materials made of aluminium, the prices start in a very affordable single-digit range (approx. 8€).
On average, handles made of stainless steel are a little more expensive than the aluminium version. Nevertheless, they start in the low 2-digit price segment (approx. 15).
In addition to their appearance, both materials also differ in their weight, as aluminium is on average a third lighter than stainless steel.
Nevertheless, both materials have a long durability. In the question about alternatives to lockable window handles, the differences between the two types of material will be discussed in more detail.
What alternatives are there to lockable window handles?
But there are also lockable window handles that have an additional alarm function, which cost a little more than the normal version.
If you live in a flat that is higher than the ground floor, there are also alternatives to lockable handles.
You can also have a grille installed from the outside to protect your children. This should reduce the chance of an accident.
Decision: What types of lockable window handles are there and which is the right one for you?
If you want to buy a lockable window handle, there are usually two types you can choose from.
- Lockable window handle in aluminium
- Lockable window handle in stainless steel
There are also lockable window handles made of brass, but these are not as numerous as the other two types on the market.
The different types each have advantages and disadvantages. Depending on what you prefer, a different type is suitable for you. In the following section, we would like to make your decision easier.
What are the advantages and disadvantages of lockable window handles made of aluminium?
A handle made of aluminium is usually cheaper than all other materials because it is a light metal. They are most often offered for security windows in the trade.
In tests, the aluminium variant often comes out on top and does not rust, so you are on the safe side when you buy it.
However, there is the possibility that condensation can accumulate on the handle. Also, the handle often does not look very classy.
What are the advantages and disadvantages of lockable stainless steel window handles?
A stainless steel handle is usually more expensive than aluminium. They are also often offered for security windows in the trade.
They usually have a higher quality design than the aluminium version. In tests, the stainless steel variant is also less successful than lockable window handles made of aluminium.
Stainless steel can be more susceptible to rust. In addition, the weight can cause problems when mounting the handle.
Buying criteria: You can use these factors to compare and evaluate lockable window handles
Now we would like to show you which criteria can be decisive for you when buying a lockable window handle.
You can use the following criteria concerning the product to better compare the handles with each other:
- The alarm function
- The resistance
- The material
- The length of the square pin
- The child lock
- The colour
In the following, we will explain what you should look for in the individual criteria mentioned.
The alarm function
First and foremost, lockable window handles provide mechanical security. However, a very useful addition is an alarm function.
Not every lockable window handle has such a function. It offers an additional deterrent effect against possible burglars.
Loud noises help to drive burglars away because they would otherwise be discovered more quickly.
Since Abus is apparently the only manufacturer to offer devices with alarm protection, such handles are not very widespread on the market.
In addition, such a function is likely to incur an additional price surcharge.
The most important criterion that should serve the purpose of lockable window handles in the first place is resistance.
What is the point of a great design if the actual function cannot be fulfilled?
You can recognise the quality of a lockable window handle by the resistance class already mentioned.
A resistance of 100Nm is generally recommended.
Of course, there are also higher resistances such as 200Nm, which result in a higher protection factor than lower values.
You should also look at the tests and consider what is the best price-performance ratio for your budget.
A particularly high burglar resistance can also have an impact on the price.
Lockable window handles can be made of different materials, each of which can have advantages and disadvantages for the product.
In the following, we would like to present these so that you have a better overview of whether and how important the material of a lockable window handle could be for you.
In addition to the most common materials such as aluminium and stainless steel, there are also lockable window handles that are also made of brass.
In addition to their appearance, they also differ in terms of wear and tear.
|Aluminium||One essential property is that it does not rust. Due to its composition, it protects itself through oxidation.|
|Stainless steel||Is heavier than aluminium and even more susceptible to corrosion.|
|Brass||Is much heavier aluminium and a bit heavier than stainless steel. Its susceptibility to corrosion is also, like stainless steel, somewhat given.|
It turns out that the lockable window handle made of aluminium is superior in properties such as weight and susceptibility to corrosion.
The robustness, i.e. the resistance to external force, can be attributed more to the manufacturer's production quality than to the material.
The length of the square peg
In Germany, there are 4 different formats of square spindles. In addition to window handles, they are also used in room, house and fire doors.
A common square spindle format for window handles is 7mm, which may differ in other countries.
However, since not every square spindle necessarily fits every window, there are also lockable window handles that have a universally adjustable square spindle.
This means that the pin adapts individually to each window. This means that there are fewer difficulties during installation.
The child safety lock
Lockable window handles are also often used as child safety devices.
Since it is no longer possible to open the window after it has been locked, such a handle can be used as such a safety device.
This is particularly useful if you live in a flat on a higher floor, for example.
But of course there is one thing you should keep in mind. It is important not to leave your keys lying around.
Otherwise, children could try to open the window with the key they found.
If you want to know more about how to store the key, you can read the trivia section below, which answers the question "Where to put the key?
Lockable window handles are also available in a variety of different colours.
If you have a particular window frame design, there is also a matching colour, just like with conventional window handles.
This applies if you want to attach importance to the appearance of your windows. The most common colours are:
There are also colours such as black, brown or gold. However, these are not as common as the colours mentioned above.
Facts worth knowing about lockable window handles
How do you install lockable window handles?
A lockable window handle is very popular as protection against burglars.
The fairly simple installation makes it easy to install even for people who are not very handy.
To make this a little clearer for you, here is a video from the company tectake showing what the components of a lockable window handle are.
Since you usually replace a conventional window handle with a lockable window handle, here is a brief description of how to install it:
- Turn the cover plate behind the handle by 90 degrees.
- Using a screwdriver, loosen the screws of the previous window handle.
- Pull off the old handle.
- Put on the new handle and screw it on again
- Turn the cover plate to the old position
After successful installation, nothing else needs to be done except locking the handle with the corresponding key, as required.
Where to put the key?
One thing you should ask yourself is how to store the key. Because this is still a problem if you have particularly young children.
Ideally, the key should be stored near the lock, out of the reach and sight of children.
There is no general solution, because every household is different. So you can let your creativity run free.
