Burglary protection


More than 1/3 of all burglaries are likely to take place during the day. Break-ins occur most often (2/3) via easily reachable windows, window doors (such as balcony or terrace doors) and doors.


Time plays a crucial role in break-ins. To protect effectively against burglary, one must envisage the model according to which most burglaries occur: most perpetrators look for the simplest and fastest access to minimise the risk of discovery. If burglars take too long, they often abandon their plans. Often just a few minutes are enough to ensure that burglars have no chance. Of course this is a rough generalisation - high risks require significantly greater delay. It is all about the individual circumstances. The corresponding safety technology, such as door and window security, can prevent burglaries if they delay the attacker for long enough.


The most important rule of building security is: The basic mechanical security of a property is the basis of the security concept. Electronic monitoring and alarm systems can only supplement mechanical security, not replace it. Because mechanical protection imposes a massive delay on attackers. For that reason police experts recommend securing a building mechanically first of all. Areas where burglars can penetrate the building are especially at risk. That means: windows, terrace doors, entrance doors, side entrance doors or cellar doors, garage doors and cellar windows.


Terrace doors / Balcony doors: a terrace door or balcony door is actually not a door in the traditional sense. It's a big window. If they are not secured, burglars can open them within a few seconds. For that reason they are especially popular with burglars. Balcony doors are also often difficult to see and easy to reach.

Do not leave windows or terrace doors tilted open when you are absent and ensure new windows and doors have at least resistance class WK2 / RC2. The classification WK3 / RC3 offers significantly more burglary protection and, in our experience, is ideal for the protection of private houses.


In principle the following applies: older wood and metal windows can generally be secured retroactively if the substance of the windows and the age of the fittings allows this. We must have a look at the window frame to make an assessment of this. You can send photos to us in advance if you wish.


Don't help burglars by leaving ladders, garden frames or other climbing aids lying around freely, as burglars will gladly also use windows and doors in the upper floors. The same applies for tools. Don't leave them lying around. There are often lots of tools and ladders in gardens and sheds, too.

Don't forget your side entrances, garages and cellar windows. Areas that are barely visible are at especially high risk.

For example, is there scaffolding around your building due to construction work, making it easily accessible or obscured from view? You should definitely report this to your insurer and take additional safety measures. In any case, heightened caution is appropriate.

Avoid anything that indicates you are absent or on holiday: does your postbox overflow when you are on holiday? Are your shutters normally open and only closed when you are on holiday? Is the garage door always open and only closed during holidays? And, of course, you should think critically about notifications of your holiday plans on social media - have you also made your children aware of this?
