As the face of a private house or apartment, the front door, of course, must be beautiful, with a high-quality outer coating. However, when buying a door to enter a house, the first thing owners think about is protection from burglars. Our advice site decided to find out which doors with what degree of protection are best to choose.
The portal wrote in detail about what kind of burglar-proof hardware for windows exists. It is also divided into reliability classes, there are only six of them. According to GOST R 51242–98 “Protective mechanical and electromechanical structures for door and window openings”, there are four classes of entrance doors, differing in the degree of protection against unauthorized intrusions.
First class doors
The most simple, inexpensive, but will not protect against robbers. According to the GOST specified by us, doors of this class must withstand only destruction and deformation by heavy objects (rods and stones), as well as deformation with a hand tool, as the document “jack type” says. And that’s all. doors of the first class of protection are easy to open without any equipment or mechanical tools. We immediately dismiss such an option as unsafe, which does not guarantee the safety of personal property.
Second class doors
Already a much more reliable option, the choice of which should be thought about. The second class provides protection against burglary using cutting and destructive tools, piercing-cutting weapons, punching from a crossbow and pneumatic weapons. But you can open such a door with an electromechanical tool in 10 minutes..
Doors of the third class of protection
Provide a reliable level of security. They have armored inserts in some places, stiffening ribs, locking crossbars located on different sides of the canvas. It is difficult to open them, you only need a powerful electric tool or an experienced burglar who will be able to cope with the locks.
Important! In any case, your front door should have two locks, and of different types – cylinder and lever, that is, safe. The first one can be used if, for example, you ran out to the store for a short time. And the second – when you need to close the house for a longer period.
Doors of the fourth class of protection
This is already an option for banks and premises that contain something very valuable. They are armored and capable of withstanding bullets and even destruction by a small charge explosion. Behind the door of IV class of protection, you can wait out the siege, waiting for help. The question is, is it necessary to overpay for such a heavy and expensive door? We are sure not! If you have an ordinary private house or cottage, you don’t need this level of protection. And from the wall of a light frame or a house made of foam blocks it will be easier for a robber to “pull out with meat”.
Most manufacturers assure that for a private house you need to choose a door with a protection class of at least III. However, according to security experts, this option may also be overkill. For example, if we are talking about a dacha that is uninhabited for the whole winter, there is no alarm, the neighbors have also left, then the burglar will be able to enter the house in other ways. Even breaking down the wall. And the door will not be a hindrance to him. The front door of the third class of protection, of course, will make the burglar tinker, but the measures to protect the house must be comprehensive.
There is no point in an expensive door with armored inserts, if you have the most ordinary windows without protective shutters and special fittings, there is no alarm, you can enter the house through the attic using an attached staircase, and so on. Therefore, you can often save money by buying a door with II class of protection. From accidental vandalism and an inexperienced amateur burglar, it will completely protect.
