Each owner of the apartment sooner or later is necessary to choose the front door. It would seem that there is nothing complicated here, but in fact this is not so, before buying the door, you need to choose it, while it should be in a state to protect the apartment from undesirable penetration. This article will propose some tips that will help you choose a reliable design.
A reliable door should have the following qualities:
– Reliability – it must guarantee that the door will not be hacked;
– The presence of a door eye;
– Sound insulation – it should prevent the hits of sounds from the street and entrance;
– Thermal insulation – it should not be pulled from it with cold, especially in winter.
The most important quality is reliability, because it is the calm and safety of the whole house that depends on it. If you choose between an iron, wooden and steel door, then only the door that is made of steel can guarantee the highest safety. This design cannot be broken or broken, even with the help of gross physical efforts. This design is quite simple, but reliable. It consists of their two steel sheets, the minimum thickness of which is 1.5 mm, and the maximum, if necessary, can be convened and 4 mm. In addition, a really reliable front door to the apartment should have stiffener ribs, the so -called spar. In addition to the fact that they significantly enhance the hacking resistance, so they still do not allow to bend the steel sheets during the load.
The second, what reliability depends on is the door box. In most cases, it is performed in two types: simple – consists of several steel profiles, and complex – such a profile is more reliable, because it is one whole -bent profile. Of course, for greater reliability, the second option should be chosen, because it does not have welds, and they, as you know, are a weak link.
Castles and loops – are important elements of protection. For optimal protection, it is recommended to install two locks. SUVALLE – it performs a power function, and it is difficult to knock it out. Cylinder – this castle guarantees protection against intellectual hacking, it is impossible to open such a castle with a master key or selection of a key, because in such a lock there are up to 3 million combinations.
But the castle will not protect the apartment if the loops on which the door holds will cut down, and then remove the door itself. In order to avoid such a situation, you need to install anti -removable pins. When the door closes, they will enter the door box’s nests and fix it, thanks to this, the design will not work to open.
Finally, I want to give advice: even the most reliable door can ruin the wrong installation, so trust this business only to professionals.
