- a fixed door frame of a frame structure, consisting of two vertical slopes and one cross member;
- opening door leaf;
- hinges providing door movement (at least 2 pieces);
- anti-removable pins that exclude the removal of the canvas (the number is equal to the number of loops);
- accessories (eyes, handles);
- technological elements (heaters, seals, stiffeners).
Criteria for choosing entrance doors
Many owners of city apartments or country houses face the question of competent purchase of entrance doors. Before dwelling on a specific model, it is necessary to formulate the requirements for a future front door .

High-quality door is not deformed during operation. Its coating is resistant to scratches and chips.
Types of entrance doors
The classification of entrance arch doors is based on the type of material used, the method and direction of opening, the purpose of the door . According to the material, metal, glass, wooden, plastic and veneered structures are distinguished. Each has its pros and cons, which must be considered when buying a door.
Table: the pros and cons of the materials from which the doors are made
| Door type | |
| Advantages | Flaws |
| Wooden door | |
| environmental friendliness of the material;ability to withstand significant loads;durability;a door made of a dense, homogeneous array has good sound insulation; | high cost of hardwood products (maple, mahogany, oak);combustibility;does not tolerate changes in humidity;susceptible to attack by pests and rot. |
| Steel door | |
| thick-sheet door (metal thickness more than 2 mm) withstands serious impacts without deforming;depending on the quality of the metal, the service life of the door is 10–40 years;fire resistance;not subject to rotting and attacks of insect pests;high level of heat and sound insulation;availability of models with special properties (bulletproof, chemical resistant); | the surface is scratched;low-quality polymer coating can lead to rust;limited possibilities for decoration and decoration. |
| Glass door | |
| tolerates high humidity;transmits sunlight;glass makes the room visually larger;modern models with tempered glass have good strength; | low strength in comparison with metal, wooden doors;the price is higher than that of plastic or veneered doors;gets dirty quickly: any touch leaves an imprint, and water drops leave stains. |
| plastic door | |
| low cost;not subject to corrosion, rotting and attack by insect pests;does not absorb moisture, provides good sealing;ease of care;light weight; | PVC product turns yellow over time;under the action of high temperatures, the plastic is melted;does not look as presentable as a wooden or glass door. |
| Veneered door | |
| with proper care, it lasts up to 15 years;acceptable sound insulation (slightly worse than solid wood doors);varnished product does not absorb moisture; | under the influence of sunlight, the veneer fades;veneer is difficult to cover curved surfaces and doors of complex configuration. |
Door assignment
By appointment, all entrance doors are usually divided into the following types:
- armored (anti-vandal) structures, which are installed in order to exclude unauthorized access to residential or public premises;
- fire doors that do not allow the spread of open flames are found in chemical laboratories, storage of flammable substances;
- bulletproof front doors – a great choice for banks, financial institutions, currency exchange offices;
- noise-absorbing structures that are used in operating rooms, recording studios.
Door opening method
According to the method of opening the valves, the products are divided into 2 types:
- Swing doors. These are the most common products. The principle of operation is to rotate the movable door leaf 180 about around hinges or hinges. A door that opens from itself to the right is considered “right”, and to the left – “left”. Products that open outward have the best heat resistance. They are safer than those that swing open inside the room. There are 2 types of swing doors:
- An interesting type of swing leaf is a pendulum, or swinging, door. The device works by rotating around its axis with the same angle of rotation in both directions. This becomes possible due to the presence of special hinges and the low weight of the door leaf. The design requires significant space, so the scope is limited to the design of the entrance to offices and shops. There are single-leaf and double-leaf models;
Entrance door dimensions
The dimensions of standard entrance doors must comply with the requirements of GOST. The following dimensions are taken as the main parameters:
- Height. Varies in the range of 2070–2370 mm. A certain value is chosen depending on the height of the ceiling.
- Width. It is determined by the number of leaves: for single-leaf products it is 1010 mm, for doors with two leaves – 1910 or 1950 mm.
- Thickness. The specific value is not regulated. It is selected based on the thickness of the walls and the purpose of the room. For metal doors, the thickness of sheet metal should be at least 1.5–2 mm.
Installation, operation and maintenance of entrance doors
The quality of the door is affected not only by the design and technology of bespoke bedside table manufacture, but also by installation . The quality of sound absorption and thermal insulation of the room depend on the installation performed.
