Doors have entered European culture since ancient times. Their purpose is to protect people from the environment and outside interference. At the same time, they were made of strong wood and upholstered in iron. Nowadays, a quality product of this type can be characterized by the words: metal entrance doors insulated street. Modern safety requirements relate in a completely new way to the appearance and material of manufacture, which naturally affects the design. However, there are several degrees of protection that are designed for a specific direction.
Cold protection
One of the main functions of the door is to protect a person from the influence of the external environment. In the generally accepted concept, this is ordinary insulation, which protects the room from subzero temperatures. The insulated street entrance door is made in such a way that special material can be placed inside it to hold the temperature. Typically, foam or mineral wool is used for this . When laying the insulation, it is recommended to place the material in a tight cavity in order to further improve sound insulation.
Penetration protection
The most important function of the door can be called protection against penetration and burglary. For this, the entrance street door is made of special steel, which can withstand significant mechanical stress. Also, special attention is paid to the hinges, which mask inside the metal box and reinforce with additional pins. It should be noted that the entrance street door should be equipped with a good and reliable lock. It should block the structure at four points of the perimeter and have a unique system of protection against burglary. It is not recommended to use cheap locks that are made of low-quality material and can be easily opened with a master key.
Vandal Protection
Recently, cases of vandalism have become more frequent when expensive and beautiful things come under attack. That is why the entrance street door is usually made of a sheet of metal, which is painted for beauty. However, thanks to new technologies, unique materials have become available to mankind that perfectly tolerate mechanical damage and are perfectly cleaned of chemical dyes of various classifications. Of these, special linings are made that are installed outside the structure. Thus, the street entrance door can withstand various degrees of damage, and thanks to special manufacturing and processing technology, it gets a stunning appearance.
Installation
Installation of doors is a very important process. The lifetime of the structure and its quality depend on it. The door should not be rubbed in, should not be skewed, open or close arbitrarily, and also contain gaps in the closed state.
Conclusion
The choice of door should be approached thoroughly. The health and well-being of the inhabitants of the house may depend on this device, which means it must be reliable and of high quality.
