What types of plastic doors are there?
The main load-bearing part of the doors is a powerful steel frame located inside the structure and rigidly connected to an external plastic profile. They also produce plastic-aluminum and plastic-wooden entrance doors for private homes. As a rule, aluminum panels are fixed on the outside of the door leaf, and wooden panels on the inside.

A feature of any design is the presence of several air chambers inside the profile that retain heat. The more there are, the better the heat saving effect.
Such doors can be equipped with any locks - mechanical single- and multi-point, special anti-burglary, automatic.
Plastic door profiles can be given any shape - regular rectangular, arched, with a beveled top edge.
In addition to standard single-leaf doors, you can order double-leaf doors with the same or different widths of the doors, and the door can be built into a frame of double-glazed windows. Unlike plastic windows, double-leaf doors are made with a hinge - instead of a fixed vertical jumper between the sashes, they are equipped with a movable profile attached to the sash, which remains closed (passive) during normal operation. The active sash is equipped with a lock and handle; it can not only open, but also recline.

The filling of the canvases can be transparent, opaque or a combination. Regardless of the type of filling, insulation of plastic doors is not required.
- The opaque filling is warm insert sandwich panels; additionally, overlay panels of various designs can be used.
- Transparent filling is a single- or double-glazed unit with triplex, mirror, tinted or embossed glass.

How to choose high-quality plastic doors?
Pay attention to well-known brands (Veka, KBE and others). Their products are of higher quality, have a long warranty and many reviews on the Internet.
Companies care about their reputation and if the product is dissatisfied or defective, they calmly replace it. Often, along with the door, installation and maintenance and periodic adjustment of the doors are included.
Profile. Choose a four-chamber or five-chamber profile for the front door and balcony. The higher the number, the better the sound insulation will be. Plastic doors for a private house must contain at least five cameras. For interiors, any option is suitable, but remember that the number of cameras also affects sound insulation.
The fittings must be of high quality. By saving, you will only get paint that quickly falls off, squeaking and eternal breakdowns.
Advantages of plastic doors and their disadvantages
If you compare metal-plastic entrance doors for a private house with metal and wooden ones in terms of characteristics, you can find many differences. Some of them are better, others are worse, so when choosing a particular design, those that are most important for each home owner are compared.
Advantages
Perhaps the main advantage of plastic doors is their aesthetics and varied design. The vast majority of private houses are equipped with plastic windows, which, despite all their advantages, do not always look harmonious in an ensemble with an entrance door made of other materials.

For reference! By ordering doors and windows as a set, you can save not only money at a decent discount, but also time searching for or ordering doors from another company.
In addition to the standard white profile, doors can be made of painted in any color or laminated, imitating different types of wood. And the internal filling can be continuous or divided by imposts (partitions) into segments of different sizes and shapes.
In addition to unique external parameters, plastic structures also have improved performance characteristics.
- They do not release heat, do not freeze, and condensation does not form on them.
Insulation for the entrance door is not needed; its functions are performed by the air chambers inside the profile and double-glazed window, seals that ensure tight pressing of the panel to the frame, and a “warm” threshold.

- Allows sunlight to enter the hallway.
The hallway or vestibule usually has no windows and is artificially lit. Glazed doors solve this problem and visually expand the space.
- They isolate noise from the street well.
This is facilitated by a double sealing circuit with a multi-layer threshold, and the presence of several air chambers in which sounds are dampened.
- They serve for a very long time.
Entrance doors made of solid wood for a private home can swell and deform when the weather changes and the building shrinks. Metal ones are susceptible to corrosion. Both require regular repairs and renewal of the protective coating. This does not threaten plastic structures.
- They are easy to care for using regular detergents.
- The canvas is adjustable.
Any house, especially a new one, is subject to shrinkage, during which the doors may stop working properly due to misalignment with the frame. In metal-plastic structures, both hinges and locking fittings are easily adjustable, and the blade can be shifted both vertically and horizontally, as well as change the degree of pressure.

- You can install it yourself by removing the sashes and leveling the frames without unnecessary load.
On a note! Plastic has a high coefficient of thermal expansion, which could cause an increase in the dimensions of the canvas and problems with its entry into the frame. But the internal steel frame, fastened to the profile with self-tapping screws, does not allow it to change dimensions with temperature changes, eliminating this problem.

Flaws
The main disadvantage of plastic structures is the instability of the outer surface to mechanical damage, the appearance of dents and scratches if used insufficiently carefully.
In addition, the PVC entrance door to a private house can be deformed under uneven load. For example, when blocking in the open position without disconnecting the closer, trying to close the door.
But the main problem is related to poor quality execution. During an external inspection of products, it is difficult to determine the thickness of the plastic and the reinforcing frame, and the strength of the connection of the internal elements. Therefore, you need to order them only from manufacturers with an impeccable reputation.
Interior doors
Interior plastic doors are characterized by all possible sizes, shapes, inserts made of glass and other materials. Due to the variety of colors and the ability to imitate any texture, the material Interior doors made of plastic has become widespread.
Their popularity is influenced by their easy care. It is enough to wipe the plastic with a damp cloth for light stains. For severe cases, liquid soap or dish soap will suffice. They do not require constant painting or varnish.
They have excellent noise-canceling properties. If you have children or are planning to, then plastic doors will help provide them with a comfortable sleep.

What to look for when choosing
If you don’t want to think about how to insulate an iron door or protect a wooden one from rotting and drying out, consider installing a modern metal-plastic structure at the entrance to the house. To ensure that it is of high quality and meets all your requirements, when choosing, pay attention to the following points.
Design Features
The main structural elements of the front door are a plastic profile of frames and sashes and a steel reinforcing frame. It is better not to skimp on their quality and choose profiles from leading manufacturers with a well-known name. Only in this case can you be sure that they will be durable and reliable, and the coating will not lose its attractiveness.
The most important criterion is the thickness of the door profile, which should be greater than that of the window profile, since plastic entrance doors for a private home experience much greater loads than window sashes.
- The minimum thickness is 70 mm; such doors are installed as backup doors in the vestibule or at the exit to a closed veranda.
- The profile of the door facing the façade of the house must be at least 90 mm.

The number of air chambers is of great importance for heat and sound insulation, of which there should be at least five in the profile of the front door.
Strength, rigidity and reliability of the structure are ensured by the internal steel frame. The thickness of the steel used to reinforce the entrance doors must be at least 2 mm, and the frame itself must have a closed rectangular or square cross-section. Some manufacturers use L-shaped or U-shaped reinforcement to reduce costs. It is difficult to verify this, which is why confidence in the good reputation of the seller is necessary.

Equipment
The degree of performance and burglary resistance that a plastic door to a private home will have depends on the quality and functionality of the fittings and locks. Therefore, you need to pay attention to the type, quantity and adjustment capabilities of door hinges, and choose suitable locking mechanisms.
Types of plastic entrance doors
When starting to choose doors, the first thing you should do is get acquainted with the range of these products on the market:
- metal door blocks are unrivaled . These doors can be classified into several classes based on the characteristics of the material used for their manufacture and the locking mechanisms. Based on these parameters, models are distinguished, starting with those that are characterized by maximum accessibility, and ending with blocks with a bulletproof coating.
- Wooden products attract attention primarily due to the beauty of the material from which they are made. However, in terms of security, they cannot meet the needs of the buyer. Therefore, the best solution seems to be to purchase a metal door with wood lining. You can think about installing wooden entrance doors if you plan to use them in a country house, where the main protective functions will be performed by other types of devices, which can be an alarm system, a fence, etc.
- In modern conditions, there is a tendency to increase the market share, which falls on plastic entrance doors . These doors are in demand primarily due to their low price and beautiful design. Such blocks, which include double-glazed windows in the design, have become widespread primarily in office buildings. Plastic can compete on equal terms and even surpass metal in a number of characteristics. Thus, among its advantages, excellent heat and sound insulation characteristics should be highlighted. When purchasing such a door block, the owner will be spared the need to insulate the door. In addition, the design of plastic entrance doors copes well with temperature fluctuations, the influence of precipitation and other external factors that can have a negative impact on the external elements of the house.
Briefly about the main thing
With the advent of modern metal-plastic profiles for the manufacture of sealed door and window blocks, there is no longer a need to think about how to insulate a metal entrance door or maintain a wooden door in good condition. Plastic structures do not have many of the disadvantages of their steel and wooden counterparts - they perfectly insulate heat and noise, are adjustable if necessary, are characterized by a long service life and ease of maintenance, and a huge number of design solutions. But all their advantages appear only if they are manufactured with high quality and installed correctly.
