We warm the Chinese front door

Split door insulation

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

At the initial stage, it is important to choose the right insulation. It is completely wrong to think that polystyrene or mineral wool is the best option.

It is much more far-sighted and more profitable to take polystyrene, which initially has a denser structure.

Next, it is necessary to establish the thickness of the insulation and its area, for which it is necessary to measure the thickness of the web, not disregarding the skin on both sides. The area is set elementarily: the height of the door is multiplied by its width. If it is necessary to insulate a structure in which there is no inner lining, an additional sheet of hardboard or fiberboard is purchased, which then covers the insulation itself.

Once all this is available, you can proceed to 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 the inside of the 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 densely as possible.
4. If you settled on polystyrene, but bought a plate thicker than necessary, hot wire or a long and thin hacksaw will help fix the issue.
5. Styrofoam or other insulation is not only squeezed between the ribs, but also 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 screw in several self-tapping 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 step in warming the door for the winter will be the comprehensive grinding of the fiberboard lining, which is done with sandpaper or a small file.

Work performance technology

To carry out the insulation process of a standard metal structure, you will need to act in several stages:

1. Initially, it is necessary to measure the dimensions of your door along with the profile. Please note that the fiberboard sheet, which is intended for sheathing the door frame from the inside, must completely hide the profile of the structure. After measurements are taken and the sheet is cut according to the measurements, mark and cut out the holes for the peephole and keyhole;
2. Using foam panels cut to size, fill a gap equal to the thickness of the frame profile by fixing them to the metal surface with silicone adhesive;
3. Fix the prepared fiberboard sheet on top with special screws screwed into the metal profile through the fiberboard. Make sure that the screws are spaced evenly across the entire surface. Then finish the edges of the sheets using a knife and sandpaper;
4. After finishing the processing of the door leaf, glue it with a sealant (foam rubber). To do this, fix the material on the frame, after removing the protective film from it.

This completes the insulation work, and you can enjoy the acquired silence and warmth of your apartment, thanks to the insulated iron door.

If you have Chinese doors installed, then over time they will also need to be insulated. Although some perform their insulation immediately after purchase. Below we offer you detailed instructions on how to carry out work on insulation:

1. The first step is to disassemble the door structure. So, on one side, completely remove the fittings and, if available, the upholstery.
2. If, during the dismantling of the facing fabric, it was not possible to maintain its integrity, then it’s not scary. It can be replaced with a fiberboard sheet. Thanks to this, you will save time during assembly by choosing an intricate configuration of a Chinese bolt or other part.
3. Further along the perimeter of the door, install a wooden frame, fixing it to the canvas with metal screws. The thickness of the rails can be up to 20 mm, equal to the thickness of the foam.
4. Now fill the entire space inside the rack structure with foam. For this work, it is recommended to use a special glue that will not deform the foam. Thanks to gluing, the foam will not hang out inside the door and crumble accordingly. The gaps between the insulation are also filled with glue.

1. When choosing foam, give preference to the material that has a high density. And given that the price of this insulation is low, it will be possible for everyone to buy it.
2. As we have already said, we will sew up the door frame with fiberboard sheets. The fiberboard sheet is fixed to the metal with self-tapping screws. It is recommended to use clamps for this work. To make it easier to unscrew the screws in the future, it is first advised to drill a hole in the frame.
3. As in the foam, and in the fiberboard, make the appropriate holes for the peephole, door lock and other door elements.
4. After preparing the fiberboard and gluing the foam, cover the foam rubber on top and cover it with the final sheathing (hardboard). In this case, the thickness of the foam rubber should be such that the fiberboard sheet can be fixed without much effort.
5. Finally, the surface is covered with leather or other finishing material. For beauty, you can also put foam rubber under the upholstery and, having thought over the figure, hammer carnations with a decorative hat.
6. Now you can install the hardware and hang the doors on the hinges.

Due to the increase in the thickness of the door after it is insulated, you may need to replace the door lock or handles. Think about this before carrying out work, otherwise you will have to sleep with open doors!

Other options for steel door insulation from Chinese manufacturers

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

• The 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. 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 box and the opening. This method 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 the purchase of high-quality rubber profiles. As a result, seals quickly fail. 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 an 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 necessary for the production of work.

In order to be safe insulate metal doors
the cause of the heat leakage must be determined. Most often, it lies in the wear of rubber seals, and their replacement will be a sufficient measure. In some cases, adjustment of the structure and, in more serious cases, its alignment on special equipment is required.

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

Most often, metal door structures are made from a corner or a 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. Styrofoam is laid in such a way that no empty spaces remain. It is glued with liquid nails. The resulting gaps are blown out with mounting foam, after drying, proceed to the next step.

The use of laminated fiberboard will make it possible to better insulate the entrance metal doors, as it will cover the unaesthetic appearance of the foam. Fiberboard is more convenient to fasten with self-tapping screws for metal, having previously drilled holes. Fiberboard sheets are fixed in the desired position with the help of clamps, holes are drilled through the sheet and screws are screwed in. It is recommended to fasten from top to bottom, as it is fastened, the sheet will gradually align.

Recently, people have become more and more interested in how to insulate a chinese door
, stamped from thin tin and inside having a lattice paper filling. In Chinese structures, all joints with the door block are quite well fitted, the paper filling makes them warmer than ordinary hollow ones, but they will have to be insulated. A heat-insulating material made of polyethylene foam (10 mm) is glued on the inside, you need to choose a material with a smooth and dense soft surface. After insulating the Chinese door with such material, it can be painted with brown (or any color) paint from a spray can. The result is an original door leaf with imitation leather.

Split frame door

When insulating a hollow iron Chinese door, attention should be paid to the choice of insulating material, since the heat and sound insulation of the room will largely depend on its quality.

Material selection

Firstly, it is better to prefer polystyrene foam to polystyrene, as it has a denser structure, which means it will last longer.

Secondly, it is necessary to purchase a heater of the required thickness and area. To determine the thickness, you should measure the width of the door at the end, taking into account the trim on both sides. We find out the area by measuring the door horizontally and vertically.

So, all the materials are prepared - you can get to work.

Removing the skin

We remove the inner door trim or prepare a new one from fiberboard or hardboard. If the area of ​​the fiberboard sheet is larger than the area of ​​the door leaf, we mark and cut out the part of the required size. Next, we determine the location of the peephole, the door handle, the protruding parts of the lock and cut out the grooves or drill and bore the holes with a file. Do not neglect the “fitting” of the fiberboard sheet to the door leaf, in order to make sure that all dimensions match.

Inside, Chinese doors have metal stiffeners that break the perimeter of the door leaf into cells. It is they who have to be filled with insulation.

Insulation installation

Expanded polystyrene is cut into pieces according to the size of each of the cells between the stiffeners. If you are not able to buy a slab of the required thickness, you can reduce it to a suitable size with a hacksaw or hot wire stretched between two wooden handles. Expanded polystyrene is attached to the "liquid nails" and slightly pressed against the metal.

Frame installation and cladding

When all the cells between the stiffeners are filled with polystyrene foam, we proceed to attach the removed skin or the prepared fiberboard sheet to the door frame.

It is more convenient to use a screwdriver with a magnetized bit or a magnetized screwdriver. In the case of fiberboard, you can also drill holes in the metal frame and the sheet itself. We screw in 3-4 self-tapping screws on each side of the door leaf and on each stiffener. If the design of the ribs is such that self-tapping screws cannot be screwed into them, we first attach a corner to each rib.

The final stage is turning the fiberboard sheet exactly under the edge of the door with a file or sandpaper.

What to do with a one-piece canvas

Of course, it would be nice if the Chinese-made iron door was initially insulated. Since this makes the final product more expensive, it is customary for us to take an economical option and improve it to the best of our abilities. In the case when the entrance door structure has one-piece panels, you need to prepare to change the internal appearance of the canvas and make a new overlay. But first things first:

The door completely gets rid of the fittings located on the inside.
An additional frame is made, as in the photo. To do this, wooden planks are fixed along the entire inner contour of the web with metal screws, the width of which should be similar to the width of the insulation. It will be better if the holes for the screws are pre-prepared in the metal base, and their diameter is somewhat smaller than the circumference of the fasteners themselves. At this stage, it is recommended to fix several transverse rails, and all wooden elements should be pulled as tightly as possible to the metal base.
Self-tapping screws must be screwed into the wood with a recess, the fixation points must be sealed with wood putty, after which all wooden parts must be painted or varnished.
Then the Chinese door is filled with the selected insulation, which is desirable not only to press well and squeeze into the newly created frame, but also to fix it with glue like the “Dragon”.
All this is covered with a fiberboard sheet of the required dimensions, which, again, is fastened with screws or even nails to wooden planks.
Foam rubber is superimposed on top, on which high-quality leatherette is stretched. The latter is attached with specific carnations with decorative or hidden caps.

In more detail, the whole process can be tracked on the video.
Since after such insulation of the door leaf it becomes much wider, it is important to buy the appropriate fittings.

Alternative ways

If you decide to protect a private house with a 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 a hundredth of its own insulation and keeping the metal sheet from freezing.

Chinese entrance doors delight owners with an affordable price and exterior. However, they do not always provide the required level of sound and heat insulation. It is quite possible to correct this shortcoming with your own hands and without serious costs.

Chinese-made doors are characterized by savings on materials.This greatly reduces their price tag in the store, but creates 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. The main reason is too thin and / or unevenly laid insulation. In some cases, it may be absent altogether;
• poor soundproofing. The main material that contributes to the absorption of external noise is a heater. If the manufacturer saved on it, then there can be no sound insulation.

Both disadvantages can be eliminated by self-laying the insulating material inside the door frame.

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

Doors from well-known brands are usually well-insulated inside and out. But if you bought an inexpensive Chinese door, you will have to insulate it yourself. In the best case, it can be disassembled into components with 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.

Work procedure:

• We remove the door from the hinges;
• Unscrew handles and door locks;
• We disassemble the door frame;
• We lay the selected insulation or blow it with mounting foam;
• We assemble the door frame;
• We fasten the handles and locks and put the door in place.

We produce insulation of 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, frost. A wooden door can dry out and crack, and frost will cover a steel door in cold weather. Therefore, complex insulation is recommended.

If you need to insulate the front door in a private house, then special attention should be paid to the insulation of both the door and the box itself.

How to properly insulate doors in a private house:

1. The sealant is glued both to the door itself and to the door frame.
2. The inside of the metal door must be foamed or filled with mineral wool (styrofoam). There should be no gaps in the material with proper installation, otherwise cold will penetrate through them.
3. Outside, the iron door can not be upholstered with anything, and it is recommended to protect the wooden door from moisture with waterproof material. Previously, cracks and cracks are smeared with special mastic.
4. Insulating material is also stuffed from the side of the living quarters. It can be leatherette with a backing, felt, an old wadded or woolen blanket.

How to insulate the door in the apartment quickly and efficiently

In apartments, the doors are not exposed to atmospheric phenomena and sudden temperature fluctuations, so the main problem is the through wind that blows through the cracks. One method to eliminate drafts is to install tight-fitting double doors. You can use a more economical way and simply stick a silicone or rubber foam seal around the perimeter. The material is sold in construction and hardware stores.

To insulate the front door to the apartment, you can use a foam seal

Sequencing:

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

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

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

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

The second option involves insulating the front Chinese door by doing the following:

• 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 of the steel door;
• a layer of glue located between the metal sheets and also fastening them is cut off with a knife;
• the inner steel sheet is dismantled or carefully bent, after which the filler is replaced with a more efficient one;
• at the request of the owner, an additional layer of heat-insulating material can also be mounted in the form of the foil-foamed polyethylene foam already mentioned above;
• upon completion of the above work, the inner sheet of metal is put in place and fastened to glue or, which is noticeably more reliable and durable, by welding using a semiautomatic device and a wire whose diameter is selected based on the thickness of the steel.

It is important to note that often the reverse installation of the steel sheet is not performed. Instead, the insulation is sheathed with some kind of decorative material or ordinary plywood.

This allows the use of a thicker layer of filler than that provided for in the manufacture of the input structure. At the same time, such an option for performing work will require the replacement of a part of the fittings, as it will lead to a change in such product parameters as the thickness of the sash.

Materials needed for work

The role of the basis of the door structure is played by a metal frame made of some profile material, sheathed on the outside with an iron sheet. This kind of door can guarantee protection against break-ins, but it will not be able to protect your home from cold air currents and extraneous sounds.

To insulate an iron door, it is worth making a choice in favor of foam panels, the thickness of which is equal to the width of the frame profile. In addition to the panels themselves, you need to purchase additional materials:

• sealing foam on a self-adhesive basis;
• sandpaper;
• adhesive tape;
• wood fiber boards;
• sealant.

You will also need the following tools to get the job done:

• jigsaw;
• electric drill;
• screwdrivers;
• sharpened cutter;
• pencil, ruler, measuring tape.

Door design options

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

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

Detachable structures imply fastening of the skin not for welding, but for 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 a metal profile, which favorably affects the mechanical strength of the structure. Detachable structures often have an inner lining made of decorative materials.

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

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

To increase the mechanical strength, the doors are equipped with stiffening ribs made of metal corners. They are located on the inside of the frame.

Conclusion

Installing and insulating a Chinese door on your own is a great way to save money.

At the same time, having competently performed each described action, you do not lose anything in quality for a low price. The materials that are necessary for work are available in every home and do not require special training.

Metal entrance doors, made by the hands of hardworking Chinese, are firmly located in the living areas and houses of our compatriots. And it does not delight, because their price, relatively high quality of workmanship and the diversity of their appearance regularly attract and call people. It is a pity that similar structures have one significant drawback - the lack of a solid layer of thermal insulation, which is unacceptable in our climate conditions.

We warm the Chinese door

as usual, home craftsmen quickly orientated themselves in the situation, and found ways of how insulate
Chinese wooden canvas to keep the costly heat of the house. It turns out that if there is 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, right?

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