Doors are of great importance in a person’s life; we can say that this is the very part of the house with which a person comes into contact most often. What we mean here is, first of all, active contact. Of course, speaking of doors, we must immediately separate the interior and entrance doors, since they perform slightly different functions, as has been discussed more than once on the pages of our website bloomhuff.com.
What's in this section
The section “Doors and everything about them” contains a large number of articles that are devoted to door structures. Our website is no longer young, so we can boast of a serious assortment of articles, including an assortment that specifically concerns doors. We have no special labor By the way, there is a search for this; you can find the information you are interested in on any type of door, both interior and exterior. We talk a lot and thoroughly about steel and wooden entrance doors, as well as door designs that are not used so often, for example, plastic doors and doors from aluminum profile. Interior doors are presented in our section no less than entrance doors. Anyone can find information on wooden, plastic and other interior doors that are used in the world. When writing articles, we take into account the fact that modern doors, moreover, this applies to doors of all types, they have a fairly serious cost, and therefore their purchase is a very responsible matter. Whenever pointing out positive or negative sides For any specific type of door, we approach this as responsibly as possible, checking the information, including in practice. And if we talk about the installation, as well as the repair of doors, then all the articles that relate to these topics are written by our specialists, who have installed hundreds of door structures with their own hands.Finding a reliable front door can be a difficult task, as most often you have to solve the “price or quality” dilemma. From the right choice design depends on the safety of not only the property, but also the owners of the premises.
First, you need to decide on the door material. IN modern world wood will not provide adequate protection, so there is only one choice - metal. Finishing is a matter of taste, but do not forget that the door will become a kind of “calling card” of the home. Study the photos of the entrance doors so as not to make a mistake with the appearance.
Secondly, good door will provide sound and heat insulation, which is especially important in northern latitudes.
Entrance door design
When selecting safety characteristics, one can be guided by the principle “the more the merrier”, but this can lead to an unjustified increase in the price and weight of the structure. Also pay attention to the ratings of entrance door manufacturers in your price segment.
The door frame is made solid, including a threshold, or U-shaped without it. The no-threshold design provides a lower level of security and is used in economy doors.
The metal part made of cold-rolled steel is more expensive than hot-rolled steel, but is of better quality: the design is durable, light and strong.
A door made of steel angle is the most a budget option, however, it is easily deformed. In a private house or entrance without an intercom, this option is the last thing you should look at.
A square profile with installed stiffeners and a sheet of steel of at least 2 mm will provide higher strength. This design can be installed in a private house.
The door leaf must be made of steel sheet with a thickness of more than 1.8 mm. Purchasing a door that is too thin is not in your interests, no matter how tempting the price may seem: opening it is as easy as shelling pears.
A high-quality door must have vertical and horizontal stiffeners. Insulation is laid between them. The more ribs, the better, but this will affect the weight of the structure. They must be evenly distributed to ensure proper reliability.
Loops
The choice is between overhead hinges, attached externally, and internal hinges, installed inside the frame.
The first type must necessarily include anti-removal bolts that prevent the door from being removed even with the hinges cut off.
Hidden hinges cannot be cut or unscrewed and are not visible from the outside. Unfortunately, there is a chance of a wedge, and then even the owner of the apartment will not be able to get home.
The loops are heavy, massive doors must have support bearings to facilitate opening and closing.
Locks
Using two locks at once will significantly increase reliability different designs: level and cylinder. One of the advantages of this approach is that if one lock breaks, you can temporarily use another. If possible, install a custom-made lock.
When installing the front door, make sure that the crab lock is installed correctly - otherwise it may jam.
The cylinder lock should be additionally reinforced with an armored lining. If the design involves a latch from the inside, this is another layer of protection.
An important point: the locks should not be closer than 25 cm to each other in order to minimize the chances of cutting them out simultaneously with a grinder.
Seals
They provide heat and sound insulation, as well as odor protection. Doors equipped with seals fit more tightly to the ledge and close more quietly.
It is not without reason that rubber is considered the best material: it is durable, hardy, and withstands various impacts. If necessary, the seal can be easily replaced with another one. Fixation occurs on an adhesive strip.
Some magnetic seals are too strong, which can make the door difficult to open.
IN apartment building One layer is enough; in particular, at least two are needed to protect against the cold.
Insulation materials
Typically used polystyrene foam, polyurethane foam and mineral wool. It should fit snugly against the stiffening ribs and frame. Cavities metal profiles are also insulated.
In a private house, polyurethane foam will serve the role of insulation better, in an apartment - basalt wool. Polystyrene foam is usually used in conjunction with polyurethane foam, which fills the resulting gaps.
Price segment
Of course, not everyone can afford an option that fully satisfies all requirements. We suggest you figure out how to choose an entrance door in different price categories.
Economy
Budget models are usually made in China, but can also be found from domestic manufacturer. The price varies between 7-10 thousand rubles.
The design provides for one sheet of steel up to 1 mm thick with a door leaf thickness of 6-7 cm. Stiffening ribs do not include additional reinforcements. The finishing is made of MDF or plywood. They can provide an attractive appearance, but the safety of such a door is quite questionable.
Average
The price can be 10-20 thousand rubles. Along with the cost, the quality of the design also increases. The middle segment door performs a better protective function.
Includes 2 sheets of steel more than a millimeter thick, the sheet itself is more than 8 cm. There are additional seals and thermal insulation. The locks are equipped with tamper-evident protection. You can choose a finish from a wide variety of more options.
Upper
The next price segment includes doors costing from 20 to 30 thousand. They provide maximum safety and reliability. They can be called the best entrance doors to an apartment.
The door locks receive enhanced protection, there are anti-removal hinges and additional stiffening ribs. When the thickness of the canvas is 8-10 cm, they are used steel sheets up to 2 mm. Good noise and heat insulation is required.
Elite
This category includes doors that cost more than 30,000 and are made according to individual order. Their main difference from the doors of the upper segment is a higher quality finish made of natural wood or stone, and the presence of forging.
This also includes armored doors, the steel thickness of which can reach 5 mm. They will withstand even a strong blow.
Some models can be controlled using a remote control.
Photo of the entrance doors to the apartment
The need to protect your home has existed since time immemorial. Historically, people saw iron as something hard and durable that could be used to protect themselves. Throughout the history of mankind, the technologies for manufacturing door structures, as well as the materials from which they were made, have changed many times. We will talk about such ordinary entrance metal doors, but as it turns out, with a huge number of interesting facts and a non-standard history. 
Interesting fact #1: In 2010, in Zurich (Switzerland), archaeologists discovered an entrance door whose age is about 5 thousand years. Thus, this find is the same age as the British Stonehenge. According to scientists, the door structure has survived to this day due to the fact that at that time the harsh climatic conditions forced people to build their houses around lakes, and this required strong wood. 
Interesting fact #2: the oldest wooden door, still in use, is located in Westminster Abbey (UK). It is reliably established that it is made of oak, felled in the 11th century. Thus, the approximate age door design is about 10 centuries. 
Interesting fact #3: All over the world, metal entrance doors are divided into 13 security classes. And if doors of 6-7 security class are found everywhere in bank vaults, then a steel door system of 13 security class is only available in Fort Knox (USA). Fort Knox is a storage facility for US gold reserves. The steel product, which reliably guards the gold reserves of the United States of America, weighs 22 tons and is 1 meter thick. It is made of seven layers of steel, and it was welded using a secret technology. 
Interesting fact #4: The tallest door in the world is located in the workshop spaceships in Florida (USA). It has a height of 140 meters, and 45 minutes is the approximate closing/opening time. 
Interesting fact #5: the heaviest door system rightfully considered metal structure, installed at the Lawrence Laboratory in California. Its weight is about 320 tons, and its thickness is almost 2.5 meters. And although it seems that with such a mass only remote opening/closing is possible, but thanks to special door hinges the system also opens manually.
Interesting fact #6: fastest closing door products installed in laboratories that work with explosives. In case of danger, they close in 0.3 seconds. Such a high speed is ensured by nitrogen compressed to 1000 atmospheres.

2. Laminated
Laminated doors are made from economical wood ( coniferous trees) with lamination applied to the surface. Laminate is a wood-cut decoration plastic film. She can imitate various breeds trees. The lamination option is considered more economical than veneering, as it is inferior in wear resistance to the coating and is less environmentally friendly.
TYPES OF DOORS ACCORDING TO THE INTERNAL FILLING
