The popularity of Chinese metal doors on Russian market input structures are explained quite simply. The fact is that such products have a cost that is much lower than the price of products of domestic enterprises. However, quite often this way of saving is achieved by significantly reducing the level of operational and technical characteristics. steel structure, as a result of which it is often necessary to insulate the Chinese front door... For this, several options for performing work are used, and the choice of a particular one largely depends on design features products.

Insulation of Chinese doors with a collapsible sash

The easiest way is to insulate the Chinese metal door in the event that its design provides for a collapsible sash. In this case, the steel sheet, which is located on the inner side of the product, is attached to the frame of the web or to the outer metal using self-tapping screws or other similar fasteners. Insulation work in this case is carried out in the following order.

First, the inner sheet of metal is removed, after which the old filler is dismantled. In most cases, it turns out to be cellular corrugated cardboard. In its place, a more modern and efficient thermal insulation material should be laid, for example, foam plastic, basalt mineral wool or expanded polystyrene. Often, polyethylene foam, ordinary or with a reflective foil coating, is used as an additional layer, which makes it possible to even more noticeably increase the insulating parameters of the structure.

In order for the insulation of the Chinese iron door, performed by the considered method, to be as effective as possible, the thermal insulation material should be laid tightly and without gaps. Bonding of joints with sealing tapes is allowed. At the end of the work a metal sheet is installed in place and carefully fixed with self-tapping screws. Naturally, all the operations described above are in most cases carried out by hand, which allows the home owner to significantly save money.

Insulation of the entrance structure from China with a non-separable canvas

It is somewhat more difficult to insulate a cheap one chinese door if it does not have a collapsible sash structure. In this case, two options apply. The first one is simpler and faster, but less effective. It involves making holes in the upper part of the web through which any free-flowing filler is poured into the inner cavity. In this role, vermiculite or polystyrene in granules can be used, as well as crushed mineral wool or other heat-insulating materials with similar characteristics.

The second option involves insulating the entrance Chinese door by performing the following actions:

• the sash is removed from the hinges;
• after that, using an angle grinder, the tacks are carefully cut off, with which the inner sheet of metal is connected to the frame steel door;
• the layer of glue located between the metal sheets and also holding them together is cut off with a knife;
• the inner steel sheet is dismantled or gently bent, after which the filler is replaced with a more efficient one;
• if the owner wishes, an additional layer can also be mounted thermal insulation material in the form of the already mentioned foamed foamed polyethylene;
• at the end of the above works, the inner sheet of metal is installed in place and attached to glue or, which is much more reliable and stronger, by welding using a semiautomatic device and a wire, the diameter of which is selected based on the thickness of the steel.

It is important to note that it is not uncommon for reverse installation steel sheet not produced. Instead, the insulation is sheathed with some decorative material or ordinary plywood. This allows a thicker filler layer to be used than was originally intended. input structure... At the same time, such an option for performing work will require the replacement of a part of the fittings, since it will lead to a change in such product parameters as the thickness of the sash.

Other options for insulating steel doors from Chinese manufacturers

In practice, there are several more options for answering the question of how to heat a Chinese front door. This can be done in the following ways:

• Execution of the outer layer of insulation, which is attached to the outer or inner side of the sash with glue or self-tapping screws. Sheathing of heat-insulating material with leatherette, vinyl leather or other leatherette is also allowed;
• Insulation of the slopes of the entrance structure and the space between the box and the opening. This method the production of work is very effective, however, it requires quite serious labor costs;
• Replacement of the seals installed around the perimeter of the Chinese steel door. In most cases, manufacturers save on purchasing high-quality rubber profiles. As a result, seals fail quickly. Work on their replacement does not require serious financial investments and large labor costs.

Do not forget about such options for solving problems with an insufficient level of insulating parameters of a Chinese product, such as installing a second door in the opening or installing a vestibule entrance structure on a common floor area. Both methods are often used in practice, since they combine efficiency and a reasonable level of costs required for the production of work.

The entrance metal doors of the Chinese manufacturer are popular. Cheapness and quite respectable appearance attract buyers. However, with the onset of the first cold weather, the question arises of the need for urgent warming. This article will reveal all the secrets of high-quality, reliable insulation and soundproofing of Chinese doors with your own hands. And you can clearly see how the insulation is carried out in the video.

Types and design features of Chinese entrance doors

Distinctive features of Chinese-made entrance doors are the small thickness of the metal used and the absence of any insulation inside. Iron does not have thermal insulation properties, therefore, it necessarily requires additional insulation. V Chinese version it is not. In this regard, when buying, immediately think over a further increase in thermal insulation.

There are two types of Chinese metal doors:

• one-piece type - in them the metal layer (sheathing) is connected to the frame by welding;
• detachable type - fastening the frame and sheathing, if done, is done with self-tapping screws. This design will not cause any particular difficulties during insulation work.

Possible insulation options

Material selection - important point in increasing thermal insulation. Remember that insulation is directly related to quality, durability and technical characteristics material. The higher the numbers, the warmer and quieter your apartment.

Ordinary cotton wool is the most unsuccessful and rarely used insulation option. It's environmentally friendly, affordable in terms of price and delivery. However, in turn, it has great drawbacks - it is afraid of moisture, quickly absorbs water particles from the atmosphere and combustible.

Mineral wool insulation - needs additional waterproofing

Minvata, its varieties - the owner of high insulating performance, environmentally clean material... However, it requires additional waste on the waterproofing layer. The hygroscopic structure facilitates the absorption of moisture from the outside.

Styrofoam, penoplex, expanded polystyrene - they are lightweight, have high technical characteristics and will reliably serve long years... The best options as insulation, hydro and sound insulator. Also affordable and fearless high humidity... They will last for more than a dozen years. The only negative is that it undergoes mechanical damage, the structure is broken and can crumble. Therefore, it is recommended to close the seal from above with a layer of hardboard or MDF panel.

One-piece door insulation technology

To raise thermal insulation properties one-piece door type in several ways:

• internal filling liquid insulation – great option, but keep in mind that with leaking seams, this material will be on the outside. The appearance at the door will spoil a little, and in this case it is impossible to guarantee the absence of voids inside. There is nothing complicated - just the inner cavity is filled with material;
• one-piece door can be insulated by attaching the insulation to the surface of the case on the inside. Of course, the appearance of the door from the inside will change, it will become many times thicker, but also warmer.

Expanded polystyrene is an excellent insulation option

The insulation technique consists in the following sequence of actions:

1. Remove the hardware from the inner surface.
2. Fasten wooden planks around the perimeter of the door with metal screws. The thickness of the plank is identical to the thickness of the selected foam, and the width is 25-30 mm.
3. Pre-punch holes in the metal. They should be slightly smaller in diameter than the diameter of the fastening screws.
4. Screw in the screws, pushing them in a little. Treat the screw-in places sandpaper, putty and paint over with enamel. This will prevent corrosion.
5. Place the foam sheets in the resulting space.
6. From above, close the insulation around the entire perimeter with a solid sheet of plexiglass, MDF plywood.
7. Install new fittings according to the changed dimensions.
8. Correct the slopes around the door frame if necessary.

The procedure for insulating a split door

The principle of insulation, sound insulation of a split-type door is identical to a one-piece door. But first remove the metal sheathing. There are stiffeners inside the structure, and lay the insulation in them.

Advice. For the convenience of subsequent work, the sheet of insulation can be attached to the metal using "liquid nails".

When the inside is completely filled with foam, instead of metal cladding use the same size MDF panel or hardboard. You can attach them with self-tapping screws along the entire perimeter.

Fix several self-tapping screws on the stiffeners (3-4 screws along the entire length of the rib). If it is impossible to fix on the edge itself, use the corners pre-attached to them.

Insulation of doors along the inner perimeter

The final stage is door insulation from the inside along the entire perimeter. Use as material polyurethane foam and rubberized insulation.

First, remove the platbands and fill the inner cavity evenly with polyurethane foam. Please note that polyurethane foam tends to expand 3 times. A few days after complete hardening, cut off the excess, protruding foam residues with a knife. Fasten the trims in place.

Get rid of gaps, gaps between the frame and the door using rubberized tape insulation glued to door frame... Check that it does not obstruct the opening, closing of the door.

So, the process of warming has come to an end. There is no particular difficulty in performing the work. So worry about possible failure not necessary. The knowledge gained will help you to simply and quickly insulate a metal entrance door without outside help.

Metal entrance doors, made by the hands of hardworking Chinese, have firmly settled in the apartments and houses of domestic citizens. And it is not surprising, because their price, relatively good workmanship and versatility appearance invariably attracts and lures people. Unfortunately, such structures have one significant drawback - the lack of a solid layer of insulation, which is unacceptable in our climatic conditions.

We insulate the Chinese door

As usual, craftsmen quickly orientated ourselves in the situation, and found ways of how to insulate the Chinese door leaf to keep precious warmth in your home. It turns out that with a minimum set of devices and skills in handling them, from budget door it is quite possible to make a real wall through which not a single draft will pass. Sounds tempting, doesn't it?

This article offers options for how you can insulate detachable and one-piece entrance canvases from China with your own hands.

Insulation of split doors

This type of canvases has inner lining, which is attached to the frame by means of self-tapping screws. There are models in which the inner lining is completely absent.

At the initial stage, it is important to choose correct insulation... It is completely wrong to think that foam or rock wool is the most the best option... It is much more far-sighted and more profitable to take polystyrene, which initially has a denser structure.

Next, you have to establish the thickness of the insulation and its area, for which you need to measure the thickness of the canvas, not disregarding the sheathing on both sides. The area is set in an elementary way: the height of the door is multiplied by its width. If a structure is to be insulated, in which there is no inner lining, a sheet of hardboard or fiberboard is additionally purchased, which then covers the insulation itself.

As soon as all this is available, you can start the process itself:

1. We remove the inner lining or cut out a new one from hardboard or other material.
2. If you have to personally make inner part canvas, you need to carefully check all dimensions and prepare holes for the handle, locks, peephole and other elements.
3. Any metal door has stiffening ribs inside, the space between which is filled with insulation, and as tightly as possible.
4. If you settled on polystyrene, but bought a plate that is thicker than you need, a hot wire or a long and thin hacksaw will help fix the matter.
5. Styrofoam or other insulation is not just squeezed between the ribs, but is additionally fixed with liquid nails.
6. We fasten the previously removed skin or mount a new one made of fiberboard. In the latter case, it is better to use a magnetized screwdriver or a screwdriver with a magnetized bit, which screws in several screws on each stiffener and on all sides of the door leaf. If, due to the design features of the stiffeners, it is impossible to screw fasteners into them, you need to additionally mount the corners.
7. The final stage of door insulation for the winter will be a comprehensive turning of the fiberboard lining, which is done with sandpaper or a small file.

What to do with a one-piece canvas?

Of course it would be nice if Iron door made in China was originally insulated. Since this makes the final product more expensive, it is customary for us to take the economy version and improve it according to our abilities. In the case when the input door structure has one-piece panels, you need to get ready to change interior view canvas and make a new overlay. But first things first:

1. The door completely gets rid of the fittings located on the inside.
2. An additional frame is made, as in the photo. For this, wooden strips are fixed along the entire inner contour of the canvas with self-tapping screws for metal, the width of which should be similar to the width of the insulation. It will be better if the holes for the self-tapping screws are prepared in advance in the metal base, and their diameter is slightly smaller than the circumference of the fasteners themselves. At this stage, it is recommended to fasten several transverse rails, and all wooden elements should be pulled as tightly as possible to the metal base.
3. Self-tapping screws need to be screwed in with a recess in the wood, the fixing points should be sealed with putty on wood, after which everything wooden parts must be painted or varnished.
4. Then the Chinese door is filled with the selected insulation, which it is desirable not only to press well and squeeze into the newly created frame, but also to fix it with glue like "Dragon".
5. It all hides behind a sheet of fiberboard the required dimensions, which, again, is attached with self-tapping screws or even nails to wooden planks.
6. Foam rubber is applied on top, on which high-quality leatherette is stretched. The latter is attached with specific studs with decorative or hidden caps. In more detail, the whole process can be tracked in the video.
7. Since after such insulation of the door leaf it becomes much wider, it is important to buy the appropriate fittings.

On final stage it is important to fill all cavities and gaps found between the box and the wall with polyurethane foam. After it dries, everything is unnecessarily cut off with a sharp clerical knife, and the joint is sealed with putty or cement.

Alternative ways

If you decide to protect private house it is the Chinese door, try to make sure that all its seams are tight. Then it will be possible to insulate the structure by filling the internal cavities with vermiculite or perlite.

And one more thing: do not rush to get rid of the ancient entrance canvas. Try living with two doors with an air cushion between them. It has excellent sound and heat insulating abilities, and is quite capable of replacing the hundredth with its own insulation and keeping the metal sheet from freezing.

In practice, the question of how to insulate an iron Chinese front door "pops up" every winter. Every year, new happy owners of inexpensive entrance metal products from China, find that they freeze, become covered with hoarfrost, "wild" cold blows from them, and so on.
The most the best option it would be correct to use such iron doors according to their intended purpose, without trying to consider them as entrance for a private house in the conditions of our climatic zone... Or buy quality entrance doors. If desired, you can find today Chinese metal doors relatively good quality and at a good price (dver16.ru/catalog/vhodnye-dveri-kitaj). But if the deed has already been done, an inexpensive metal Chinese front door has already been installed, Finishing work finished, I do not want to change anything. And I want to modernize what we have with a little blood. The search for masters begins, the most "desperate" tips on how to insulate an iron Chinese front door with your own hands are listened to and read on forums on the Internet. None of this makes any sense.
The first popular advice on how to insulate an iron Chinese front door with your own hands. Warming "in the middle".
You will not be able to insulate an iron Chinese front door yourself, precisely because it is a fairly high-tech metal product. It is impossible to make changes to the factory design with your own hands. It is practically impossible to think of a way to "disassemble and then assemble" this metal door. Disassembling it is simply not provided by the manufacturer. Being "forcibly" disassembled, thanks to Russian ingenuity, the Chinese iron door actually falls apart, more precisely: it is irreversibly deformed, because it was assembled at a special stand, where individual elements structures are exposed and fixed with assembly equipment. Read - they are pressed with clamps. Without factory equipment, stand and special equipment he cannot "become normal." That is, the most familiar technology for insulating metal doors from Russian and Ukrainian manufacturers: disassembly, filling with foam and "reverse" assembly, is not applicable here in principle, due to the design features.
Trying to blow foam into the door leaf through holes drilled in the metal yourself is an absurd idea. The product is not only deformed, but all locking rods will be jammed, and most likely, the lock will fail. In addition, inside the iron Chinese door is not empty, as many people think, but a paper cellular insulation is laid there. Garbage is rare, however, there is simply nowhere to blow the foam. Plus, the door design provides inner frame door leaf, reminiscent of thin metal partitions, which also will not allow you to fill normally and evenly inner space polyurethane foam.
The second popular tip is how to insulate an iron Chinese front door yourself. Insulation "inside and outside".
Theoretically like auxiliary option if it is impossible to properly fill the door leaf in the middle with heat-insulating material, you can try to sew inner side iron Chinese door, something that does not let the cold through. Developing the "concept", it would be logical to sheathe or revet "at the same time" and the outer side of the entrance door made of iron. The method, in principle, is useless, because it is ineffective. However, a metal door from a local manufacturer can indeed be sheathed with thick wood trims. It will look beautiful and will slightly warm the front door. At least she will not freeze like that and "cry" with dew. The trouble is that local manufacturers use welded hinges and loot designs with a very large margin of safety. Chinese iron entrance doors have a completely different design of loot and hinges. Even a small additional load quickly and completely irreversibly spoils such products. Don't be fooled by the "status" of a metal front door. Yes, it is really iron, but not strong.
