Production of entrance doors in modern world has received very widespread development thanks to mass construction apartment buildings megacities and other cities of regional and district significance. Owners of their own houses and cottages do not lag behind apartment owners. The development here is very dense, and many owners of private houses pay special attention to the issue of choosing an entrance door. Wooden, plastic and metal doors for private country house enrich the market with new and improved models, and the openings that occur over time force us to constantly improve the technical quality of the security of the front door.
In order to correctly determine how to choose an entrance door for your home, let’s look at the main features of different types of street doors. Exists fundamental difference between the external door to a private house, cottage or any administrative premises and internal door to an office or apartment. The external entrance door to a house or building represents a kind of barrier separating the street from the interior of the house. As a result, the doors are exposed to solar radiation, various precipitation, changes in humidity and temperature. It is recommended to choose doors for a wooden country house based on the weight of the door itself. Let's talk about metal, wooden and plastic entrance doors in relation to the analysis of their burglary resistance and others technical characteristics.
Wooden entrance doors
Traditional wooden entrance doors for a private house are made of wood different breeds, with blank (or glass) frames or panel sheets. External wooden doors have increased weather resistance, i.e. reliably resist solar radiation, moisture and sudden temperature changes.
The thermal conductivity coefficient of wood λ = 0.15-0.25 W/m*K (depending on humidity and wood type) provides wooden doors with high heat transfer resistance. IN winter time year, the front door does not become covered with frost from the inside, does not freeze and does not allow the lock to freeze, which many metal doors cannot boast of. Since metal conducts cold well into the house from the street, frost forms on the inside of the metal door, causing the lock and door frame to freeze. An array of wood successfully bypasses this obstacle. But during sudden changes, condensation often forms on doors with glass inserts. The insert, like a window, sweats, saturating the door leaf with moisture and creating additional stress on the wood.
wooden street door
Wooden entrance doors of type DN (GOST 24698) are installed in a standard type doorway in the walls of buildings. They have the following dimensions:
opening height(in mm):
- 2070;
- 2370;
doorway width(mm):
- 910;
- 1310;
- 1010;
- 1550;
- 1510;
- 1910;
- 1950.
Plastic doors
Plastic entrance doors to a private house are mostly made of glazed PVC profiles in accordance with GOST 30673-99. To glaze the door, a single- or double-chamber double-glazed unit is used, with a heat transfer resistance of 0.32 m²*°C/W for a single-chamber package and from 0.49 m²*°C/W for a double-chamber package. Reduced heat transfer resistance door block made of plastic at least 0.8 m²*°C/W. Which doors to install, with or without glass, depends on the features of your home and individual preferences.
plastic street door
Installing a plastic entrance door with high thermal insulation qualities will be an ideal option for an office or a small private house or administrative premises that are not equipped with a cold vestibule. Good external doors made of plastic prevent frost, ice or condensation from falling out. To ensure that the room does not freeze, it is recommended to provide insulation for the front door in advance.
Metal doors to the house
With regard to metal doors, the main indicator of strength is the material used for their manufacture. According to the main production component, metal entrance doors to a house are divided into:
- steel;
- aluminum.
The aluminum entrance door leaf is extruded profiles aluminum alloys. A steel door is characterized by cold-rolled or hot-rolled steel, combined with bent steel profiles.
A metal door is always cold by definition, because... this material conducts heat well. Thermal insulation values for steel are approximately 60 times lower than those of plastic or wood, and 3 times lower than aluminum.
metal street door
Those. Moisture inevitably condenses on a metal door leaf, especially when high humidity outside air. Street doors equipped decorative panels, prevent freezing. But condensation still forms. Steel door, insulated with polyurethane foam, allows to increase thermal insulation to some extent, which will prevent the formation of large amounts of moisture. To eliminate the problem of freezing of a metal door, profiles with thermal inserts are used in their production. This is a thermal break - a material with low thermal conductivity. We'll talk about this in more detail later.
Table: comparison of characteristics of different types of doors
Metal, plastic and wooden external doors differ in a number of quality and technical characteristics. If the buyer is wondering how to install an entrance door so that it is protected from the outside and serves for many years, then it is more convenient to compare the general properties of all three types of products. Below are comparative analysis doors made of different materials.
| Characteristic | Metal | Wood | Plastic |
| Burglary resistance | the most reliable in terms of burglary resistance | has a medium burglary resistance class | not a very hack-resistant option |
| Noise insulation | on the highest level | slightly lower than metal, but higher than a plastic box | significantly isolates from extraneous sounds with additional inserts |
| Thermal insulation | lets in the cold a lot | highest thermal insulation rate | mid-level thermal insulation |
| Accessories | Door locks and handles are elegant and durable | it is possible to install the most luxurious fittings, suitable different types | there is an opportunity to experiment with the most different options accessories |
| Door frame | made of one or two sheets of metal with stiffeners | solid or hollow box adds, prevents moisture formation | door frame made of plastic or metal-plastic, it is possible to hide the hinges |
| Aesthetics | strict and seasoned design | the most elegant external doors in appearance | the canvas is usually made in strict lines |
Safety
The issue of outdoor door security is in first place in reviews of any manufacturer, so it is very important to take seriously such door elements as locks, hinges, stiffeners, and burglary resistance class. When choosing an external door, it is advisable for the homeowner to give priority to the degree of protection. Let's take a closer look at the main security components of an external street door.
Burglar resistance classes
According to GOST R 51072-97, there are a total of 13 classes of burglary resistance of the entrance door. Of these 13 classes, only the first 4 belong to external street household doors. Classes from 5 to 13 are related to heavy armored doors not intended for residential buildings– safe and bank doors.
The table below clearly demonstrates the burglary resistance classes. The main indicator of strength is the resistance coefficient of the entrance door, taking into account the application various kinds opening tools. Partial access is the opening of a door leaf with a template (hole) diameter from 12.5 to 35 cm. Full access is an opening with a template diameter of 35 cm.
Door locks
Door locks are very diverse in their design, fastening and features of use. The main indicator of the difference between locks is the cylinder mechanism, i.e. a sign of an internal locking mechanism. Based on this quality, door locks are divided into:
- cylinder;
- pin;
- disk;
- electromechanical.
Cylinder mechanism quite widespread - used on entrance and, in some cases, interior doors. The principle of operation is the presence of a rotary cylinder with small secretions (protrusions) that form a non-repeating combination. Only a native key with the necessary serifs can move such secrets. Therefore, each lock has an individual set of projections. In order to prevent drilling of such a mechanism and further hacking, cylinder locks are additionally equipped with an armor plate on the other side.
door lock
Level types mechanisms assume the presence of a metal plate inside the lock - a lever. The key of such a lock with code notches makes it possible to position the locking components in the right place to open the lock. It is almost impossible to pick a lever lock using a master key.
Pin lock often used in metal entrance doors. The principle of its operation is the presence of non-spring bolts that block access to the house. These bolts are driven by a key that pulls back the pins on the reverse side. If you need to enter the house without a key, it is possible to saw the crossbars visible between the door and frame. Since such a lock is not sufficiently reliable, it is appropriate to combine it with one of the above types locking mechanisms.
pin lock
Secrets disk mechanism consist of wraparound discs. When the lock is opened, they are brought to a coded position. It is very difficult to open it with a master key. In addition, if you try to drill out its cylinder, the disks of the mechanism will begin to rotate along with the drill.
Electromechanical- the most modern type of castle. Its mechanism is based on interaction internal system secret combinations with electrical impulses. The mechanism is activated to unlock the door by issuing a coded signal. The key fob, magnetic card, code combination and button on the back serve as the key for this lock. An important disadvantage of the lock is its dependence on the power supply.
To visually familiarize yourself with the capabilities of modern locking mechanisms, we invite you to see photos and prices various types door locks.

Loops
An equally important part of an external street door is its hinges. By type of design door hinges are classified So:
- invoices;
- mortise;
- corner;
- screw-in;
- hidden;
- double sided
hinges for front door
GOST 5088-2005 does not indicate differences between overhead and mortise hinges. Both types are card hinges that scroll to the door leaf and frame. The difference stands for preliminary preparation opening and surface of the canvas:
- installation of overhead hinges does not require special training;
- mortise models will require cutting a recess in the door frame and the end of the leaf in order to recess the card plate there.
Difference corner hinges from invoices consists of a design in terms of fastening. To the axial rod corner hinges not two flat plates are attached, but two profile angles. This form of cards makes it possible to install them on doors with a vestibule. The loop is attached to the end of the canvas using a mortise method. They are convenient to place in the opening, but they stand out against the background of the overall design.
Screw-in hinges– these are two symmetrically located cylindrical parts with holes for screws. Two such cylinders replace flat cards on mortise hinges. That is, one cylinder is fixed with screws on the frame, and the other on the door leaf. The advantage of these hinges is their versatility: there is no need to select right or left hinges. But they are installed only on doors with a European door. It is impossible to attach a domestic door leaf to them.
Hidden hinges give the front door a special aesthetic appearance. When the door is locked, such hinges cannot be seen. They are not divided into right or left. The hinge design has at least three rotary axes. Due to the complexity of their installation, it is recommended to seek installation assistance from specialists.
Double-sided loop belongs to the category of card canopies. Its main purpose is to ensure easy opening/closing of the door leaves in both directions - outward or inward. For ordinary housing, such designs have not found popularity, because In essence, they are more suitable for installation in conference rooms or formal living rooms.

Narthexes and platbands
A door vestibule is a design of the ends of the door leaf when part of it covers a certain portion of the door frame. The porch is often also called a “quarter”, because its thickness is equal to a quarter of the thickness of the door leaf. The advantage of a rebated door:
- thermal insulation;
- soundproofing;
- aesthetics;
- masks gaps.
door ledges
The outer door trim is a decorative strip that covers the junction of the wall and the door frame. A modern manufacturer very often adds a platband to his product. But often homeowners prefer to make the trim for the front door with their own hands. Platbands (or extensions) will perfectly complete the image of any design.
Additional protection systems
Here we note that in addition to the main means of protecting the street door, deviators. These are additional vertical crossbars, closed and opened using the same lock. The manufacturer often adds stiffening ribs to the design of a metal door to prevent breaking (bending) of the door leaf. The box design itself is, as a rule, solid-bent (not boiled), i.e. consists of solid metal bent at four corners.
deviator
To prevent the door from being removed from its hinges, anti-removal pins are used, located in the hinge area of the door leaf in areas that are difficult to reach. cutting tool places. Additional pads on the locks make it difficult to knock out or drill out the lock. The internal filling of the lock also prevents it from being broken into. It is not uncommon to use double or triple rebates, completely eliminating the excess gap.
Video: front door safety class
We present to your attention the following video clip, clearly demonstrating how the burglary resistance class of an external door affects the time it takes to open it. The video shows an example of breaking into an entrance door, taking into account many of the features and structural protection systems mentioned above.
Doors with a thermal break: to prevent freezing
Door thermal break is ensured by the presence of an insulating layer with a low degree of thermal conductivity. Basically, it consists of a polyamide layer of different thicknesses. The material spreads over the entire area inner surface canvases. The side of the insulation layer faces the street. A layer of insulation on the street side helps reduce thermal conductivity between adjacent materials. Entrance doors with a thermal break for a country house, a closed steel profile is used. This reduces the likelihood of heat loss.

Designs with glass
Recently, external doors with glass inserts have become increasingly popular. This protected double glazed windows like a triplex on a car. It is possible to have decorative grilles that enhance the safety of doors with glass. Often, entrance doors with glass for a country house use a special protective film for glass class in accordance with GOST R 51136-98. Installing such a film significantly increases the burglary resistance class of a door with glass, which is confirmed by Order of the Ministry of Internal Affairs of Russia No. 78 148-94.

Finnish doors for a country house
Finnish entrance doors for a country house are made according to a special concept of a “warm entrance door”, combining stable heat and sound insulation, aesthetics and durability. The door is mainly frame type. Its frame is made of dense pine timber. Then a two-layer sandwich panel is sewn on both sides to form the door leaf.
Finnish street door
First layer The surface of the Finnish entrance door is a durable HDF sheet with a high density. Second layer– aluminum sheet that repels moisture and maintains the integrity of the structure. The filling used is environmentally friendly foam insulation – freon-free polystyrene foam. The canvas turns out to be much lighter than a massive door. Experts noted that Finnish doors are extremely resistant to temperature changes on both sides of the door leaf up to 60 degrees.
Entrance door device
Entrance street doors- quite heavy structures. For a metal door, the average weight is about 100 kg. In addition, locks, escutcheons and metal trims. A well-protected structure reaches a weight of 150 kg or more. A standard iron door weighs 60-80 kg.
Let us note the main design characteristics entrance metal door:
- door steel frame;
- anchors for attaching the box to the wall;
- seal around the door perimeter;
- door leaf made of profile, makes up the door frame;
- stiffening ribs to provide additional strength;
- two mortise locks;
- insulation and sound insulation;
- outer steel sheet;
- inner steel sheet;
- anti-removal locks (pins);

Do-it-yourself door installation: installation rules
Entrance door installation Doing it yourself is always a responsible task, and in most cases new for the home owner. Let us outline in order the general basic rules for installing entrance wooden, metal or plastic doors.
- Before work startsIt is strongly recommended to clean the installation area by removing furniture, electrical appliances and other items home interior. Some (non-removable) nodes protect plastic film. Wiring and other cables are removed during installation. The door frame is covered on three sides with special masking tape to preserve the paintwork.
- Along the contour door frame, the mineral plate included in the door delivery kit is installed.
- Installation mounting eyelets. The box itself, on linings, is carefully inserted into the opening. The level indicates the horizontal alignment of the lintel and threshold, the vertical position of the door frame pillars. Holes for fasteners are drilled.
- Installation of the door leaf. It is hung on the door frame. It is important to ensure that the locks and handles are working properly. If something is wrong, the door frame lock post is adjusted using shims.
- The void between the wall and the box filled with polyurethane foam or sand-cement mortar.
- For street doors without entrances (in Vacation home, to the dacha) you need to make a canopy or construct a vestibule.
The task of how to make a high-quality installation of an entrance door is always an option; it requires increased attention from homeowners and consideration of small installation details.
Where to buy and how much it costs
On the question of how to buy a reliable street door at reasonable price are treated with an inherent sense of skepticism. Many companies offer doors at unreasonably high prices that do not meet the required security standards. Average prices for good quality entrance doors from:
- metal – 55,000 ₽;
- wood – 30,000 ₽;
- plastic – 20,000 ₽.
When choosing an entrance door, proceed, first of all, from the purpose of its acquisition. Your choice – country house or apartment, office or production room– the individuality and technical features of each model are important everywhere. It is very useful to take into account reviews from owners of specific models. In order to better reflect the described qualities of entrance doors, here are several photos of different types of door components.
Such manufacturers, as Guardian, Forpost, Granit, Torex and a number of others are able to offer customers quality products at affordable prices.
When choosing a door, the customer also decides on its configuration. The complete set of metal doors is divided into regular, that is, standard, which is initially provided for in the price list, and additional (which the client can order in addition to the door, for an additional cost).
The usual configuration of metal doors involves
- door frame;
- door leaf;
- one or more stiffeners (depending on the type of door);
Additional equipment can be agreed with the client, it may include:
- closer;
- main and additional locks;
- decoration;
- door knob.
Thus, when purchasing a metal door, it is necessary to proceed from what functionality it will carry. And based on this, determine it technical indicators and appearance.

When choosing perfect door There are a few things to pay attention to:
- the material that formed the basis of the door leaf;
- dimensions of the entrance structure;
- style and design.
Wooden doors
Doors made of natural wood remain the most popular - they are reliable, durable and look presentable. Solid wood is used for their manufacture, wooden boards or wood and metal panels. Depending on the source material, the structure may be strengthened by inserting sheet metal.
Entrance doors from natural wood They perfectly protect the house from heat loss and last a long time.
Plastic doors
The basis of plastic entrance structures is plastic sheets, which are additionally insulated to increase thermal insulation properties. In addition to preserving heat in a living space, plastic doors have such advantages as good sound insulation and resistance to corrosion. Such doors have a low cost and are easy to install.
Metal doors
Due to their performance properties, metal doors to private homes are gaining increasing popularity. To ensure high strength and burglary resistance, manufacturers use steel sheets with a thickness of 1.2 to 2 mm. Doors must be equipped with stiffeners - transverse, longitudinal or combined.
If the highest strength is required, then you should pay attention to armored models. They are made using a special safe technology, when concrete is poured inside the frame.
Types of doors
Depending on the size, all entrance doors are divided into:
- single-leaf;
- one-and-a-half, consisting of a narrow part (about 30 cm) and a wide part (about 90 cm);
- bivalve.
Single leaf doors are much more often used in ordinary apartments, while for the equipment of the entrance area in a private house, one-and-a-half or double-leaf structures are chosen. The difference between double doors is not just the larger width of the door leaf, but also the presence of two hinges and a connecting locking mechanism.
How to order a door?
