How to insulate a Chinese iron entrance door. How to insulate an iron Chinese entrance door How to insulate a Chinese entrance door

The popularity of Chinese metal doors on Russian market input structures are explained quite simply. The fact is that similar products have a cost much lower than the price of products from domestic enterprises. However, quite often this way to save money is achieved by significantly reducing the level of operational and technical characteristics steel structure, as a result of which there is often a need to insulate Chinese front door. For this purpose, 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 leaf

The easiest way to insulate a Chinese metal door is if its design includes a collapsible door. In this case, the steel sheet, which is located with inside products, is attached to the canvas frame or outer metal using self-tapping screws or other similar fasteners. Insulation work in this case is carried out in the following order.

Removed first inner sheet metal, after which the old filler is dismantled. In most cases, it turns out to be cellular corrugated cardboard. A more modern and efficient one should be installed in its place. thermal insulation material, for example, polystyrene foam, basalt mineral wool or expanded polystyrene. Often, polyethylene foam, regular or with a reflective foil coating, is used as an additional layer, which allows for an even more noticeable increase in the insulating parameters of the structure.

In order for the insulation of a Chinese iron door, carried out using the method under consideration, to be as effective as possible, the thermal insulation material should be laid tightly and without gaps. Sealing 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 done by hand, which allows the home owner to save significant money.

Insulation of entrance structure from China with non-removable fabric

It is somewhat more difficult to insulate a cheap one Chinese door, if it does not have a collapsible sash design. In this case, two options apply. The first of them is simpler and faster, but less effective. It involves making holes in the upper part of the canvas, through which some kind of bulk filler is poured into the internal cavity. In this role, vermiculite or polystyrene foam in granules can be used, as well as crushed mineral wool or other thermal insulation materials with similar characteristics.

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

the sash is removed from its hinges;
after this, using an angle grinder, carefully cut off the tacks that connect the inner sheet of metal 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 carefully bent, after which the filler is replaced with a more effective one;
if the owner wishes, an additional layer of heat-insulating material can also be installed in the form of the above-mentioned foil-foamed polyethylene foam;
at the end listed works The inner sheet of metal is installed in place and attached with glue or, which is noticeably more reliable and durable, by welding using a semi-automatic machine and wire, the diameter of which is selected based on the thickness of the steel.

It is important to note that the reverse installation is often steel sheet is not produced. Instead, the insulation is sheathed with some kind of decorative material or regular plywood. This allows the use of a thicker layer of filler than what was intended during manufacture entrance structure. At the same time, this option for performing the work will require replacing part of the fittings, as 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 warm a Chinese entrance door. This can be done in the following ways:

Making an outer layer of insulation that is attached to the outside or inside of the sash using glue or self-tapping screws. It is also allowed to cover the heat-insulating material with leatherette, vinyl leather or other leather substitutes;
Insulation of slopes of the entrance structure and the space between the frame and the opening. This method production of work is very effective, however, it requires quite serious labor costs;
Replacement of seals installed around the perimeter of a Chinese steel door. In most cases, manufacturers save on purchasing high-quality rubber profiles. As a result, seals quickly fail. Replacing them does not require serious financial investments and large labor costs.

Do not forget about such options for solving problems with insufficient insulation 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, as they combine efficiency and a reasonable level of costs required for the work.

In order to reliably insulate metal entrance doors the cause of the heat leak must be determined. Most often, it lies in the wear of the rubber seals, and replacing them will be a sufficient measure. In some cases, adjustment of the structure is required and, in more serious cases, its alignment using special equipment.

First, the gaps in the frame and the door frame are eliminated. The presence of cracks can be checked visually or by pressing, the existing play is eliminated. In the places where the box is attached to the walls, the old foam may come off; such places need to be re-foamed or simply plugged. Many people mistakenly believe that the glued sealing rubber (the same as on metal-plastic windows) will improve insulation of metal doors. Such a seal will only add problems, since metal structure has no gaps. The perimeter of the vestibule must be covered with foam rubber sealant. It is glued to the frame profile, closer to the inner edge. If the thickness of the foam is greater than the thickness of the gap, one edge is cut off at an angle. When closing the profile, door leaf should be pressed against the foam rubber only near the very edge on the inside.

Most often, metal door structures are made from a corner or square pipe, which creates cavities inside the door leaf. Insulation of metal doors involves filling this cavity with heat-insulating material. Most often, foam plastic with a thickness equal to the depth of the internal cavity is used for this. The foam is laid in such a way that there are no empty spaces left. It's sticking liquid nails. The resulting gaps are blown out polyurethane foam, after drying, proceed to the next stage.

The use of laminated fiberboard will allow better insulation of metal entrance doors, as it will cover the unaesthetic appearance of foam plastic. It is more convenient to fasten fiberboard with metal screws, having previously drilled holes. Fiberboard sheets are fixed in the desired position using clamps, holes are drilled through the sheet and screws are screwed in. It is recommended to fasten from top to bottom; as you fasten, the sheet will gradually level out.

IN Lately, people increasingly became interested in how to insulate a Chinese door, stamped from thin tin and having a lattice paper filling inside. Chinese designs have all the joints fitted quite well with door block, the paper filling makes them warmer than regular hollow ones, but they will have to be insulated. Thermal insulating material made of foamed polyethylene (10mm) is glued to the inside; you need to choose a material with a smooth and dense soft surface. After insulating a Chinese door with such material, it can be spray painted with brown (or any color) paint. The result is an original door leaf with imitation leather.

Chinese entrance doors delight owners with their reasonable price and appearance. However, they do not always provide the required level of noise and heat insulation. It is quite possible to correct this shortcoming with my own hands and without serious costs.

Doors made in China are characterized by savings on materials. This greatly reduces their price tag in the store, but gives rise to a number of problems:

insufficient thermal insulation. It can manifest itself in the form of cold drafts from the corridor and the appearance of condensation on the inside of the door. main reason- insulation is too thin and/or unevenly laid. In some cases it may be absent altogether;
poor sound insulation. The main material that helps absorb external noise is insulation. If the manufacturer saved on it, then there can be no sound insulation.

You can get rid of both disadvantages by installing insulating material inside the door frame yourself.

Door design options

The most common two options for installing entrance doors are detachable (collapsible) and permanent (non-removable). One-piece doors have the following features:

The basis of the frame can be not only a metal profile, but also a simple metal strip or corner;
there may be no internal stiffeners;
the casing is made of thin metal and welded to the frame.

Detachable structures involve fastening the casing not with welding, but with self-tapping screws. This slightly increases the cost of the door, but greatly improves its maintainability and simplifies modernization. In addition, to facilitate the installation of panels, most manufacturers use metal profile, which has a beneficial effect on the mechanical strength of the structure. Detachable structures often have interior lining from decorative materials.

In addition to the frame, insulation and cladding, Chinese metal entrance doors are supplied with the following elements:

door frame. Most often made of metal. In cheap options, it may not be included in the price, but must be purchased separately;
lock and handle. Can be combined or installed separately; Some lock models are equipped with vertical locking bolts, which increases the vandal resistance of the structure
peephole

To increase mechanical strength, doors are equipped with stiffeners made of metal corners. They are located in the inner part of the frame.

Insulation technology

The sequence of actions will largely depend on the design of the door.

1. One-piece doors

To insulate them, the following steps are performed:

We insulate the door from the inside

the lock with the handle is removed;
A frame made of wooden beams is installed around the perimeter of the door from the inside using self-tapping screws. The section of the beam is selected so that one of its sides corresponds to the depth of the internal space door frame. You can focus on the thickness of the door, but at the same time take into account the thickness of the outer sheet of metal. The easiest way to fasten the timber is with self-tapping screws, having previously drilled holes of a slightly smaller diameter in the frame for them;
at distances of one and two thirds of the door height, horizontal crossbars from the same timber are installed;
to strengthen the wooden frame, its elements are additionally tightened with metal corners;
Pieces are cut out of a sheet of expanded polystyrene, equal in size to the resulting cells inside the wooden frame. If the thickness of the polystyrene foam is excessive, then it can be cut with a saw with a wide blade or use a wire cutter;
The inner surface of the door is thoroughly cleaned and degreased. If there are burrs or metal deposits, they are removed with sandpaper or a grinder with a grinding wheel;
the prepared polystyrene foam is glued inside the wooden frame. You can use ready-made polyurethane adhesives or dilute dry glue yourself, suitable for working with similar materials. When gluing, it is necessary to ensure that there is no free space between the metal and polystyrene foam;
A fiberboard sheet pre-cut to the size of the door is placed on the frame. The sheet must provide seats under the lock and peephole. You can fasten fiberboard either with small nails or self-tapping screws. The heads of nails and screws must be completely recessed. If possible, they should be sanded and puttied;
A foam sheet is placed on top of the fiberboard. The presence of foam rubber will improve the exterior, as well as enhance the heat and sound insulation qualities of the door;
The foam rubber is covered with leatherette, dense fabric or other material with similar properties. For fastening, furniture nails with large heads are used;
The lock, handle and peephole are installed.

2. Split doors

A special feature of split doors is the presence of a ready-made spatial frame inside the door. Therefore, before insulating the Chinese iron door, there is no need to install in it wooden frame, as is the case with one-piece models.

We insulate inner space split door

You need to start insulating by removing the inner door trim. It can be secured with screws or glued. In the first case, you need to find the fastening points and unscrew the screws. Perhaps they will be hidden by decorative caps. In the second case, the sheathing will have to be cut off, which will make it unsuitable for installation back after laying polystyrene foam.

The remaining steps will be the same as in the case of a permanent door. The only difference is that the fiberboard sheet will not be attached to wooden beam, and with self-tapping screws directly to the metal door frame. Therefore, you need to pre-drill holes in the frame with a diameter slightly smaller than the diameter of the screws used.

Alternative insulation technologies

In addition to polystyrene foam, other materials can be used to insulate doors:

We insulate the doors with a rubber lining around the perimeter of the frame

corrugated cardboard or honeycomb insulation is one of the cheapest options, but can only be used in mild climates or in apartment buildings with warm staircases;
felt. Its main advantage is environmental friendliness;
foamed polyurethane. This material is similar in characteristics to expanded polystyrene, but is softer, has a smaller thickness and is sold in rolls;
polyurethane foam. Poured into the space between the inner and external cladding doors. The excess that has leaked out is removed with a knife;
vermiculite - loose mineral material, poured into the interior of the door. Requires good fit of panels to ensure tightness.

Enhance thermal insulation properties doors can be installed by installing sealing rubber pads. They are attached along the inner perimeter of the door frame and must fit snugly to the door leaf closed door. This eliminates drafts and conserves heat.

Let's sum it up

Self-insulation of a Chinese iron door is a good option save, but not lose in comfort. The materials used are inexpensive and do not require special skills to work with them.

Metal entrance doors, made by the hands of hardworking Chinese, are firmly located in residential areas and the homes of our compatriots. And it doesn’t delight, because their price, relatively high quality of workmanship and diversity of appearance regularly attracts and calls people. It’s a shame, similar structures have one significant drawback - the lack of a good layer of thermal insulation, which is unacceptable in our climate conditions.

We insulate a Chinese door

as usual, home craftsmen quickly got their bearings in the situation and found ways to insulate Chinese wooden canvas to preserve expensive heat at home. It turns out that if you have a very small set of devices and skills in handling them, it is quite possible to make a real wall out of a budget door, through which not a single draft will pass. Sounds tempting, don't you agree?

This publication offers options on how you can do it yourself insulate detachable and one-piece entrance panels from China.

Insulation of split doors

This type of panel has an internal lining that is attached to the frame using self-tapping screws. There are models in which there is absolutely no interior lining.

At the first stage, it is important to choose a good insulation. It is completely wrong to think that polystyrene foam or mineral wool is the most perfect option. It is much more prudent and useful to take polystyrene, which initially has a denser structure.

Next you have to determine the thickness of the insulation and its area, for which you need to measure the thickness of the fabric, not ignoring the sheathing on both sides. The area is inserted simply: multiply the height of the door by its width. If you are going to insulate a structure that does not have internal lining, an additional sheet of hardboard or fiberboard is purchased, which then covers the insulation itself.

Once all this is in place, let's begin the process itself:

We remove the inner lining or cut out a new one from hardboard or other material.
If you have to make the inside of the canvas yourself, you need to carefully check all the dimensions and prepare holes for the handle, locks, peephole and other elements.
Any metal door has rigid ribs inside, the space between which is filled with insulation, as densely as possible.
If you settled on polystyrene, but bought a plate thicker than necessary, hot wire or a long, thin hacksaw will help fix the problem.
Polystyrene foam or other insulation is not simply squeezed between the ribs, but is also additionally secured using liquid nails.
We screw on the previously removed sheathing or assemble a new one made from fiberboard. In the final version, it is most advisable to use a magnetized screwdriver or a screwdriver with a magnetized bit, which is used to tighten several screws on each stiffener rib and on all sides of the door leaves. If, due to the design parameters of the rigid ribs, it is impossible to screw fasteners into them, you need to additionally install corners.
The final step in insulating the door for the winter will be the multi-sided grinding of the fiberboard lining, which is done with sandpaper. grinding work or a fine file.

What to do with one-piece fabric?

Of course, it would be great if the iron door from China was initially insulated. Since it makes the finished product more expensive, it is customary for us to take a budget option and improve it using our knowledge. In case the entrance door design has one-piece panels, you need to be prepared to adjust internal view canvas and make a new overlay. But first things first:

The door completely gets rid of the fittings located inside.
An additional frame is made, as in the photo. For this, throughout inner contour the blades are fixed with self-tapping screws for metal wooden planks, the width of which should be similar to the width of the insulation. It is very good if the holes for the 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 secure several cross bars, and all wooden elements should be pulled tightly to the metal base.
Self-tapping screws have to be screwed into the wood, the fixation points must be sealed with wood putty, after which everything wooden parts First of all, they are painted or varnished.
Afterwards, the Chinese door is filled with the selected insulation, which would be good not only to press and squeeze perfectly into the newly created frame, but also to fix it with “Dragon” type glue.
All this is covered with a sheet of fiberboard of the required dimensions, which, again, is attached with screws or even nails to wooden planks.
Foam rubber is placed on top, over which a good leatherette is stretched. The latter is attached with non-traditional nails with decorative or hidden heads. The whole process can be followed in much more detail using the video.
Since after similar insulation of the door leaf it becomes much wider, it is important to purchase the necessary fittings.

On final stage It is important to fill with installation foam all the voids and cracks found between the box and the wall. After it dries, everything is cut off unnecessarily with a sharp utility knife, and the joint is sealed with putty or cement.

Alternative methods

If you understand, save a private house specifically a Chinese door, try to make sure that all its seams are tight. Then the opportunity will arise insulate construction by filling the internal cavities with vermiculite or perlite.

And one more thing: do not rush to free yourself from the ancient entrance canvas. Try to live with 2 doors, between which there will be air bag. It has excellent sound and heat insulation abilities, and is quite capable of replacing self-made insulation with hundredths and keeping the metal sheet from freezing.

Chinese door repair.

It’s quite possible to choose insulation for your front door yourself if you study the advice of experts in advance To keep your house or apartment warm in winter, it is recommended to insulate the home from the inside, for example, by covering the windows with paper or construction tape. But it will be more effective to insulate the entire house, in particular the doors. Exist different ways stop the access of cold air from the street or corridor. And properly selected insulation for the entrance door will protect the apartment not only from drafts, but also from extraneous noise penetrating from outside.

The best insulation for doors: types and characteristics

You can insulate your front door both from the inside and outside. In the first case, the empty cavity inside the frame is filled with insulating material, which sometimes also serves as sound insulation. And the second option involves eliminating the gaps and cracks between the door and the jamb. The doors can also be upholstered on the inside and outside with dense material, which will help keep the room warm.

Acquainted with various types insulation for doors and their characteristics can be found in specialized stores

The most popular types of insulation:

Rubber or foam tapes. One of the sides of the tape is treated with an adhesive substance, so when the protective layer is removed, the foam or rubber is firmly glued to door jamb. The door is perfectly sealed, and the wind will no longer blow through it.
Corrugated cardboard. This is one of the cheapest insulation materials, but not very effective. In addition, it is highly flammable. That's why corrugated cardboard more used as a sound-absorbing material. The use of corrugated cardboard is justified when there is no more material at hand. suitable insulation or the budget for its purchase is limited.
Mineral wool. Retains heat perfectly, does not burn and does not allow extraneous sounds to pass through. If you properly fix the cotton wool inside the door frame, it will last for many years without requiring replacement. Incorrectly laid cotton wool will sag downwards and will not protect against the cold.
Construction foam. This material perfectly fills all cavities, and thanks to its cellular structure it retains heat perfectly. Its application does not require special construction skills, so insulation work possible alone.
Styrofoam. One of the most popular insulation materials. It is very light, so it will not weigh down even a metal door. The air-filled bubbles keep out the cold and sounds from the street. Polystyrene foam is very cheap, which is why it has become so widespread.
Sintepon. Basically it is stuck on outer side doors and requires leatherette or vinyl leather upholstery. With a small weight, synthetic winterizer retains heat well.

All necessary materials can be bought at hardware stores.

A simple way to insulate your front door with your own hands

Doors from famous brands usually well insulated inside and out. But if you bought an inexpensive Chinese door, you will have to insulate it yourself. IN best case scenario it can be disassembled into its components using a screwdriver, but you may have to cut off the inside with a cutter or metal scissors. Then it will need to be carefully welded back or replaced with plastic with a beautiful pattern.

In order to insulate the most simple door, it will be necessary to first disassemble the structure into individual components

Work order:

Remove the door from its hinges;
Unscrew handles and door locks;
We disassemble the door frame;
We lay the selected insulation or blow it with foam;
Assembling the door frame;
We screw on the handles and locks and put the door in place.

If the inner part of the doors could not be put in place, then it can be successfully replaced by horizontal strips of plastic placed in a special corner screwed around the perimeter of the door.

How to insulate a door in an apartment quickly and efficiently

In apartments, doors are not exposed to atmospheric conditions and sudden temperature fluctuations, so the main problem is the draft wind that blows through the cracks. One method of eliminating drafts is to install tightly fitted double doors. You can use more in an economical way and just stick on silicone foam rubber or rubber compressor along the perimeter. The material is sold in construction and hardware stores.

To insulate the entrance door to an apartment, you can use a foam rubber seal.

Sequencing:

First you need to measure the gap between the door and the frame in order to buy insulation of the required thickness;
Then the seal is glued around the perimeter or pressed into a special groove.

If the seal is not selected correctly, the door will close with great difficulty or will not close at all, and the locks and handles will quickly become unusable due to increased loads.

Outside doors in apartments are upholstered with vinyl leather, leatherette or genuine leather, having previously insulated them with foam rubber or batting. Stepping back about 5 millimeters from the edge of the door leaf, the material is nailed down. This must be done with special nails with a wide head or a construction stapler. The sides can be decorated with a wide strip of leather or leatherette. The inside of doors in apartments is usually not insulated.

We insulate the front door in a private house

In the private sector, it is necessary to insulate the front door especially carefully, since it is not protected from rain, snow, wind, and frost. Wooden door may dry out and crack, and steel will be covered with frost from the inside in cold weather. Therefore, comprehensive insulation is recommended.

If you need to insulate the front door in a private house, then Special attention You need to pay attention to insulation of both the door and the frame itself

How to properly insulate doors in a private house:

The seal is glued both to the door itself and to the door frame.
Inner part metal door need to be foamed or filled mineral wool(foam plastic). Gaps in the material when correct installation should not remain, otherwise the cold will penetrate through them.
The outside of an iron door does not need to be upholstered with anything, but it is recommended to protect a wooden door from moisture with waterproof material. The cracks and cracks are first covered with a special mastic.
Insulation material is also placed on the living room side. It can be leatherette with a backing, felt, an old cotton or wool blanket.
