What makes the anti-burglary door safe?

According to statistics, more than a half of all burglaries to houses and flats take place through doors. The intruders usually do not attempt to undertake any sophisticated and more complex methods, while we, having not earlier considered to have a robust, anti-burglary, outside door, may only facilitate their job. Therefore, with regard to our personal safety and to safety of our close ones, as well as of our material goods, it is a good idea to invest in a good, anti-burglary door. And what specifically makes such a door really safe?

First, their proper size, weight and appearance.iary, waga i wygląd drzwi

While selecting anti-burglary doors, we may choose many interesting and very elegant models, which perfectly fulfil their protection function, while not necessarily looking like an armoured door. The factors, which make the anti-burglary doors safe, include also their weight and size. The anti-burglary doors are now available in standard and non-standard sizes, however, the height of a door leaf in the doorframe opening should never be below 2 m. In turn, the width of such doors should never be below 90 cm. Regarding the door weight, we should not expect that we can bring an anti-burglary door home under our arm. The weight of anti-burglary doors usually varies between 60 and 90 kg but there are models, weighing between 120 and 140 kg! Why such a door weight range? The weight of doors results from the thickness of metal sheet and trusses, the applied finish material and, of course, the door size.

Second, the doorframes, hinges, inserts

In order to ensure that anti-burglary doors will accomplish their expected task, the doorframes should be made of metal. It is also important that the doorframes were deeply anchored in a wall – best if they are embedded or screwed into the wall. The door should, in this case, have, at least, three hinges. The modern hinges of GERDA doors allow for a precise and free adjustment of the door leaf with regards to the doorframe. But it is not only the door structure, which is important for safety level. A major role is also played in this aspect by an insert to the lock, which has to comply with numerous requirements, confirmed by appropriate safety certificates. Keep also in mind that the more bolts our doors have, the safer they are. It will simply be more difficult for burglars to force such a door.

Third, the resistance to burglary

In order to make doors qualified as anti-burglary, they have to meet very strict structural requirements and be in line with the guidelines, regarding the applied materials. In turn, such achieved resistance to burglary is then submitted to verification and properly classified, according to applicable European resistance classes, i.e. from 1 to 6. Before we decide to purchase an outside door to our flat or house, the risk of burglary should be considered and defined. If the risk is high, as there have been several burglary incidents around, we should consider buying a door in burglary resistance class 3 or 4. In other cases, if the risk of burglary is low, it is enough to have an anti-burglary door in resistance class 2.
