Often when studying quality characteristics, features and parameters of doors, you may encounter incomprehensible abbreviations and abbreviations that make it difficult to understand the material presented by the manufacturer. To understand the essence of what is written, it is not necessary to become an expert in the field of the door industry or try to take the place of the manufacturer. This article will help you figure it all out.
Many standard meanings are used to shorten long words. For example, in documents on certification, standardization, as well as in the catalogs of many manufacturers, you can find the following abbreviations:
DG– the door is solid;
DHF- solid paneled door;
BEFORE- glazed door;
DLO\DOL- glazed laminated door;
DFO\DFO- paneled glazed door;
DN– external door;
DU– reinforced or insulated door;
DSH– panel door (with prefix U – reinforced);
DS– service door;
DK- a door on which the canvas swings.
Many words are not clear in their meaning, as they have foreign origin or unclear definitions. Let's look at some of them using an example:
Mold– if the doors are paneled or glazed, these elements are enclosed in a profile with an edge shape.
Knobset– handle-knob.
Layouts– profile slats that hold the glass in the door.
Block- a structure that already consists of interconnected door frame (door jamb) and door leaf with fittings.
Doviator– a mechanism for locking doors on all sides.
Dormas, backset– the distance from the front of the lock to the keyhole.
Fusing– stained glass decorative element decorating the door instead of glass.
Panel– thin frames in the door leaf stand out as a decorative element.
In the descriptions of doors from the DoorExpo company and other manufacturers, there is often an indication of the materials that are used for their production. The most common for doors and door fittings are:
Antipyrine– impregnation, which increases the fire-resistant properties of the door leaf.
MDF– wood-fiber board, which is used for cladding or making elements of interior doors.
Powder paint- is polymer material, providing protection metal elements or the entire steel door.
Silumin– silicon-aluminum alloy, from which fasteners, handles, and locks are made.
Veneer– cut, felling of natural wood.
TsAM– an alloy of 3 steels: zinc, aluminum, copper.
The next time you see these words and abbreviations, you will be able to understand what characteristics the manufacturer has endowed with its doors.
Today there is no person who has not heard of PVC doors, also called metal-plastic or simply plastic. Using them in Everyday life, how often have we wondered what it is?
Such doors are usually made from polyvinyl chloride (PVC) material reinforced inside aluminum structures. Hence the name - metal-plastic. PVC is a difficult to ignite and self-extinguishing material, resistant to atmospheric influences, as well as the destructive effects of alkalis and acids, and not subject to rapid wear. It is these characteristics that allow it to be used for the manufacture of door frames. Also, a PVC door is much cheaper and often more beautiful, as evidenced by customer reviews.
Anyone who buys a PVC door should know that the opportunity to choose a truly high-quality product is regulated by law. Since 2002, the State Standard for metal-plastic doors has been in use. It is called “Door blocks made of polyvinyl chloride profiles” (GOST 30970–2002).
This standard describes the main types of metal-plastic doors and their technical characteristics required by production. GOST obliges manufacturers to adhere to all quality standards described in it. Therefore, when purchasing a metal-plastic door, in order not to blindly trust the seller, it is important to understand the basic concepts of GOST.
Typology of PVC doors according to GOST
In accordance with GOST 30970–2002, metal plastic doors share:
- Regarding the purpose, the door can be external or internal. An internal door can be an interior door, an entrance door to an apartment or for a bathroom;
- Regarding the type of filling of the door frame:
- glazed PVC door, into the frame of which a double-glazed window or transparent glass of any type is inserted;
- a blind door whose door leaf is opaque. It can also be: light (when the lower part of the door is not transparent, but the upper part allows light to pass through) and decorative (when the PVC door leaf is equipped with an architectural pattern);
- Regarding its design, a metal-plastic door can be:
- with one canvas (right or left) and with two canvases (the same or different widths);
- with a fixed sash or one that opens;
- with or without a threshold, with or without a frame box;
- regarding the type of PVC profile.
Here the classification is based on the number of cameras profile system, from which the door is made. Profiles come with two, three or big amount cameras;
- Regarding the profile finishing option, the PVC door can be white or another color, covered with a laminating film or with a co-extruded front covering.
Technical requirements for PVC doors according to GOST 30970–2002
The state standard quite strictly regulates the parameters that the production of plastic doors can afford - these are dimensions, filling of the canvas, permissible deviations during manufacturing. Accordingly, requirements are put forward in relation to fittings. also in this document measures for quality control of products, standards for their packaging, transportation and storage are prescribed.
Operating characteristics of a plastic door
To ensure that the door you buy satisfies your needs and maintains the necessary microclimate in the house, when choosing, you need to pay attention to its main characteristics:
- Heat transfer resistance may depend on thickness insulation material, but should not go beyond 0.8-1.2 m²xC/W.
- Air permeability is no more than 3.5 m³/(hm2).
- Insulation from sound waves is not less than 26 dBA
- The state standard also establishes that the number of years of use for a PVC profile must be at least 40, for a double-glazed window - at least 20, for a seal - at least 10. The number of openings and closings during this period can be at least 500,000 times.
Strength groups of metal-plastic doors
When purchasing, the strength group of the door is also an important indicator. There are only three of them: A, B, C. The strongest, according to this GOST classification, are the doors of group A. You can also find out about this by reading customer reviews.
What deviations can be considered a defect in the production of PVC doors?
Manufacturing in violation of requirements State standard, occurs in cases where:
- There is a difference in the dimensions of the finished product and the dimensions indicated in project documentation. The difference should not be more than 2 mm and less than 1 mm. The difference in diagonal length for PVC doors should not exceed 2 mm for a door leaf measuring 1.5 sq.m and 3 mm for larger doors.
- Scratches, chips and other deformations are found on the door leaf, as well as differences in color or gloss that are visible to the naked eye.
- The door opens and closes with strain and force.
- There are deviations technical specifications, from the one stated in the documentation.
- Deviations from GOST requirements during installation.
When purchasing a PVC door, do not forget that you have the right to demand compliance with the requirements of the State Standard from any company operating in the Russian Federation.
All applicants to mass production Standardized construction doors must be marked, which clearly states the type of door leaf, its dimensions and data on the relevant GOST. However, it is quite difficult for a consumer who is not privy to the intricacies of deciphering door brands to understand all these letters, numbers and hyphens.
Structure symbol, And full transcript they are presented below.
So, the marking has the following (conditionally designated) form:
XY2-1ZG.
It should be noted that the full decoding of the marking will differ depending on whether we mean an external or internal door.
X - first position points to product type. In the case of a door, there will always be one of two letters:
- The letter D, which will indicate that you are dealing specifically with the door block, and not with anything else.
- The letter P indicates that in front of you is a separate leaf that is not equipped with a door frame.
Y is the letter that is on second position, denotes type outer door . There are 3 options:
- N - wooden vestibule doors.
- C - service doors.
- L - hatch doors and manhole doors.
In case of internal doors in the second position(Y) will be one of the following letters:
- G-blocks with a blank canvas.
- O-blocks with glazed sheet.
- K - door blocks with glazed swinging panel.
- U-block with continuous internal filling.
So, next to the H marking you can see ranges with a height of 21 dm and a width of 9, 10, 13 or 19 dm. Next to the C marking there are ranges 16-19, 19-9, 21-13, next to L - 10-10,13-13, 13-15.
Brand types O and K may have standard sizes: with a height of 21 dm and a width of 8,9,10, 13 dm; height 24 dm and width - 10,12,15,19 dm.
Types of brands G and U - can have one of the above-mentioned (typical for O and K) sizes, and also meet the dimensions: 21-7 and 21-12.
Z - the letter immediately following the numbers indicates various characteristics of the door. Here you can find the following symbols, the full decoding of which is given below:
- B - has the characteristics of increased moisture resistance.
- L - left.
- N - with float.
- P - with a threshold.
- C - with continuous filling of the canvas.
- T - difficult to burn.
- Ts - with internal continuous filling of the panel using wooden slats, equipped with a threshold, an embedded cylinder-type lock and a sealed rebate.
- Shch - panel type door.
- O1, O2, O3 - options for outer door upholstery.
G - the last position in the row of markings contains the name of the current GOST.
An excellent illustration of the complete decoding of the markings can be examples:
- DO24-15P. Double glazed door, height 24 dm and width 15 dm, right, with threshold.
- DG21-7LP. Solid single-leaf door for an opening 21 dm high and 7 dm wide, left, with a threshold.
- DN21-19PSCHO2. External vestibule door and input type for size 21*19, right with threshold, panel with second upholstery option.
- DS16-19GU. External service door for opening with dimensions 16*19, solid, insulated.
As you can see, a complete decoding of door brands is not accompanied by any particular difficulties. Be sure to pay attention to the markings - and you are guaranteed to choose the door you need! Read the details for ordering door blocks and all the necessary information on the main page.
Components door block: canvas, frame box, fittings.
Plastic entrance doors have a U-shaped welded PVC frame with an aluminum (low) threshold. Balcony doors are framed around the perimeter.
We produce single-leaf doors (left/right-hand version), double-leaf doors (with a mullioned or mullion-free rebate, including with leaves of different widths), with a vertical impost, adjacent blind or translucent frame filling - in accordance with GOST 30970 "Door blocks made of polyvinyl chloride profiles".
According to design options, door blocks are divided into:
- single-leaf doors (left and right opening), double-leaf doors (including with leaves of different widths), with a vertical impost and adjacent blind or translucent frame filling;
- doors with a transom (opening or non-opening);
- doors with a threshold on mechanical connections (for example, aluminum), without a threshold, with a closed frame frame (threshold from the same frame profile).
Door blocks are divided into internal and external.
Marking:
- “DPV” is an internal door block made of PVC profiles (intended for use inside a building: interior doors, for plumbing units, apartment entrances, etc.) door blocks,
- "DPN" is an external door block made of PVC profiles (entrance to buildings, structures, as well as vestibules).
By type of filling, door blocks are divided into:
- glazed (filled with double-glazed windows or various types sheet glass: patterned, tempered, multilayer, reinforced, etc.);

Today, in the construction products market, PVC doors (made of polyvinyl chloride) - external, interior and balcony - have confidently consolidated their positions. Production synthetic materials presents durable and wear-resistant doors, especially since their cost is pleasantly surprising compared to other analogues.
PVC doors are increasingly being chosen for door filling interior openings In public, industrial and residential premises, as external ones, plastic products are used somewhat less frequently.
All enterprises specializing in the production and installation of plastic doors base their work on a specific GOST 30970 “Door blocks made of polyvinyl chloride profiles”. It was developed in 2002 as the State Standard of the Russian Federation. This GOST regulates the production of doors and door blocks from polyvinyl chloride profiles.
The current GOST 30970 governs the production of DPV and DPN doors for buildings and premises for various purposes. It is important to consider that balcony blocks, as well as units with increased operating requirements, cannot be manufactured based on this GOST.
Thus, plastic doors made of PVC profiles are used in sanitary institutions, laboratories, and enterprises Catering, educational and medical organizations. No less often they are used to fill openings interior partitions offices and residential premises (for bathrooms and toilets).
Positive features of plastic doors
Manufacturers of PVC doors claim that such products are natural and safe, since only high-quality substances are used in their manufacture. This is especially true for those who plan to install a plastic door in a children's room.
It is worth noting that the frame of a PVC product is much lighter than one-piece designs. And all because under a thin polyvinyl chloride film there is a dense MDF flooring, which sets the shape of the structure, obtaining the effect of elasticity and reducing the main load on the doorway.
One of the most attractive properties plastic products is not only the simplicity of the design, but also a high degree of sound insulation. The fabrics and the structure as a whole do not transmit heat well and they are moisture resistant, which leads to resistance to high temperatures, and therefore the product does not deform - it does not reduce its dimensions and does not shrink.
Ease of operation lies in the possibility of frequent processing of the door block detergents. Wide range color range and the possibility of applying a pattern to the canvas, make appearance products even more attractive.
What types of plastic doors are there?
According to the prescribed standards GOST 30970-2002, doors made of polyvinyl chloride profiles are classified according to several main characteristics, namely: purpose, core material, design solution, types of finishing.
Important to remember! Balcony doors and doors in areas of high flammability are not regulated in accordance with GOST 30970-2002, and cannot be classified.
Classification by purpose
By type of destination, plastic blocks are divided into:
- Outdoor units acting as entrance doors in buildings and structures (especially moisture-resistant) and vestibules.
- Internal door products, which are designed to fill interior openings, for bathrooms and other entrance doors used for use inside the building.
Classification by type of door leaf filler
Based on the type of filler, the blocks can be glazed with patterned, tempered, multilayer, reinforced, etc. double-glazed windows inside the panel, and blind, which are characterized by continuous filling of the panel, without the use of transparent materials.
Door leaves are called light when they combine glass and opaque filler. Decorative plastic products are distinguished by the presence of complex architectural patterns on the surface of the product.
Classification by type of construction
Based on constructive solution, plastic doors are divided into single-leaf and double-leaf, respectively, they can be with the doors opening to the right and left, or with different widths of the leaves.
The presence or absence of a threshold and transoms also refers to a sign of a design solution.
Classification by type of finish
Based on the criterion for dividing PVC doors by type of finish, the blocks are:
- white;
- colored;
- laminated ( decorative cladding film);
- with paint coating.
Design features
Production and operation door products made of plastic is carried out entirely in accordance with GOST 30970-2002. The block box acts as frame structure, welded from PVC profiles, which are reinforced with steel liners.
For a more durable connection of each box profile, the best option is welding. The threshold may be either absent or in the form of a metal overlay.
The current GOST applies to external and interior doors area up to 6 square meters, at the same time, the area of each separately opening leaf should not exceed 2.5 square meters.
A prerequisite for the production of a structure is to equip it with functional holes that serve for drying the cavities between the canvases and other elements. Without them, if necessary, it will be extremely difficult to drain water from the structure. Thus, plastic doors are moisture-resistant and ventilated.
The most important! Facade surface The product sheets and boxes must be covered with a protective self-adhesive film.
Accessories
The finished product kit includes: profiles, double-glazed windows, gaskets for sealing, door fittings.
PVC profiles are made from rigid weather-resistant polyvinyl chloride, they are durable, moisture-resistant and geometrically unchanged. The double-glazed window must be mounted from durable and anti-nuclear glass that meets all requirements. Sealing gaskets run along the entire perimeter of the box and fit tightly to avoid drafts and distortions of the structure.
An elegant and aesthetic look to doors, can give wide choose accessories. As with balcony doors, products according to this standard are equipped with similar hinges and locking mechanisms.
Finally
The popularity of plastic products is explained by the affordability of prices combined with the compliance of all necessary requirements according to GOST 30970-2002. Cheap material PVC provides the opportunity to create a high quality, reliable and attractive product. This is perfect combination prices and quality.
