Attractive price encourages some to buy chinese doors for installation in private houses and apartments. And although such products are suitable for these locations, their insulation characteristics are not the best. If the region has a cold climate or the entrance has broken glass, then sooner or later the owners will have to think about how to insulate the Chinese metal entrance door. This can be done externally or internally. Each option will require its own tools and materials.

External insulation of a Chinese door

If a Chinese door is installed in a country house, then it can be modified with your own hands without the involvement of specialists. In view of minimum requirements In terms of decor, taking into account the place of use, the insulation of the Chinese door is carried out with felt. It is bought 4-6 mm thick in a roll. The color is optional, but gray or brown is less dirty.

The work will be carried out from the indoor side to preserve the water-repellent coating on the outside. Before installing the insulation, the handles, their linings and the peephole are removed from the door. You can attach the felt layer with glue or rivets. If the first option is chosen, then the material is cut strictly according to the dimensions of the sash. The metal surface should be degreased and Moment glue should be applied around the perimeter of the canvas and several vertical stripes in the central part. Applying a sheet of felt, it is aligned along the edges and smoothed to remove blisters or irregularities.

If the rivet fixation method is chosen, the material can be cut with a margin of 20 mm per side and tucked inward. This will look more beautiful visually and thicken the insulation area on the porch. Fastening is carried out with a screwdriver with a thin drill, after which the rivet is immediately installed. They are placed at intervals of 100 mm from each other. It will also be necessary to make two transverse rows so that the material does not puff up in the middle.

How to insulate a Chinese door from the inside

Insulating the structure from the inside is more difficult, since the manufacturers initially did not provide for disassembling the fabric. It is assembled using electric rivets using resistance welding. But painstaking work justified by the fact that it allows you to maintain the attractive appearance of the product, which is so important for the apartment. You can disassemble a Chinese door using a grinder and a thin cutting disc, as well as a knife with a thick blade.

The process is performed in the following sequence:

1. The bolts holding the hinge strips are unscrewed on the canvas and the sash is disconnected.
2. It is placed on a table or other elevated surface for the convenience of subsequent manipulations.
3. The design has two steel sheets bent into a box shape and connected resistance welding every 150 mm. On the hinge side, you need to find one such fixation point and try to pass the disk between the sheets of iron to cut it off. You shouldn’t go too deep - 2-3 mm is enough.
4. After practicing on convenient location When cutting tacks, you should do this along the entire contour.
5. Then a knife is driven between the sheets and separates them. You need to act carefully, since the steel is very thin and easily deformed.
6. It is enough to bend three sides, which will open access inside and allow you to insulate the Chinese entrance door.

After this, you need to remove the corrugated cardboard, fixed with glue. Mineral wool is placed inside the sash, the thickness of which is selected based on the depth of the canvas. If the disassembly was carried out carefully, then the sheet of metal is returned to its place and fixed with short tacks using a semi-automatic machine with 0.8 mm wire at a minimum current. The end will then have to be repainted.

In case of severe warping of thin steel, the sheet on the room side is removed. Then you will need to put inside the canvas wooden beam along the perimeter, which is fixed at the ends with self-tapping screws. A couple more stiffening ribs are placed inside. Mineral wool is laid between them. From the outside it closes MDF panel, but no more than 6 mm thick, so as not to create excessive load on the points of fixation of the wooden part to the iron.

Alternative methods of insulation

In each of the above cases, you will need to change the sealing contour around the perimeter, which will eliminate drafts and noise. But if you don’t want to disassemble the structure, and gluing felt on the outside seems too rough, then you can insulate a cheap iron Chinese door from the inside through drilled holes at the top end.

Three holes with a diameter of 10-12 mm are enough. Through them, the inner corrugated cardboard is crushed with a metal rod so that it does not create obstacles for subsequent actions. Foam granules are poured into the resulting free cavity. Since the substance becomes electrified and adheres to the walls, it will have to be compacted wooden slats and tapping.

Another alternative is low expansion foam. To bring it inside, holes 4 mm in diameter are drilled at the end around the perimeter and sealant is applied. You will first need to crush the corrugated cardboard with short rods.

The Door Base online store has a large assortment of insulated models that do not have to be modified later. If you have any difficulties with Chinese doors regarding their insulation or assembly, then we can easily find a replacement for them at an affordable price.

In order to reliably insulate metal entrance doors the cause of the heat leak must be determined. Most often it lies in wear and tear 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 the 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 with 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 of equal depth internal cavity. The foam is laid in such a way that there are no empty spaces left. It sticks 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. Stick on the inside thermal insulation material made of foamed polyethylene (10mm), 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.

The iron door serves not only reliable protection prevents unauthorized persons from entering the apartment, but also prevents the penetration of cold air and noise. Ideal option is an iron door, the kit of which already includes insulation material.

However, there are cases when inexperienced buyers purchase a design with a poor insulation system, or they specifically buy such a door in order to save money. In such a situation, you need to insulate the door yourself.

In this article we will tell you how to insulate an iron entrance door with your own hands, consider the option of a Chinese door, and also give photo and video instructions.

Methods

In Russian construction market there are special fillers designed specifically for insulation door designs. Today, the following types of insulation materials are very popular:

• construction slabs mineral wool;
• basalt wool as a filler;
• insulating foam.

Each metal door must be equipped with a rubberized or foam seal. It is necessary for additional sound insulation when closing and preventing cold air from entering the apartment from the outside.

Besides good result Treatment of all cracks and gaps with polyurethane foam provides protection against noise. Moreover, in this case, the polyurethane foam has similar functions to the insulation.

Materials needed for work

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

To insulate iron door, you should make a choice in favor of foam panels, the thickness of which is equal to the width 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.

Work execution technology

To carry out the insulation process standard metal structure you will need to proceed in several stages:

1. Initially, you need to measure the dimensions of your door along with the profile. Please note that the fiberboard sheet, which is intended for covering the door frame on the inside, must completely hide the profile of the structure. Once the measurements have been 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 required size, fill the gap equal to the thickness of the frame profile by fixing them to the metal surface with silicone glue;
3. Secure the prepared fiberboard sheet on top using special screws screwed into metallic profile through fiberboard. Make sure the screws are spaced evenly across the entire surface. Then sand the edges of the sheets using a knife and sandpaper;
4. After finishing processing the door leaf, cover it with sealant (foam rubber). To do this, secure the material to the frame, having first removed the protective film from it.

At this point, the insulation work is completed, 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 people insulate them immediately after purchase. Below we offer for you detailed instructions how to carry out insulation work:

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

1. When choosing polystyrene foam, give preference to the material that has a higher 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 cover the door frame with fiberboard sheets. The fiberboard sheet is secured 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 recommended to first drill a hole in the frame.
3. As in foam plastic, so in fiberboard, make appropriate holes for the peephole, door lock and other door elements.
4. After preparing the fiberboard and gluing the foam, cover it with foam rubber on top and cover it with the final covering (fibreboard). In this case, the thickness of the foam rubber should be such that the fiberboard sheet can be special effort secure.
5. Finally, cover the surface with leather or other finishing material. For beauty, you can also put foam rubber under the upholstery and, having thought through the shape, hammer in nails with a decorative head.
6. Now you can install the fittings and hang the doors on their hinges.

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

Many domestic consumers often have a question: how to insulate a Chinese iron entrance door? Metal doors from Chinese manufacturers are very popular, because they have good quality and reasonable price. Their only disadvantage is the absence of a layer of insulation, which is simply necessary under our climatic conditions. In order to understand how to insulate a Chinese iron entrance door, the video lesson will tell you quickly, and the article will tell you efficiently.

There are several types of insulation to insulate a Chinese door. Most often used:

1. Liquid. These include polystyrene foam and penoplex. They are easy to install and have affordable price. This best option For country house or dachas.
2. Soft. These include glass wool and mineral wool. This is an environmentally friendly and fire-resistant material. Created for front door in apartments and small spaces.
3. Inflatable. For example, polyurethane foam. The main difference is the high cost and decent quality.

It is also worth considering additional materials and tools for insulation.

Insulation of split doors, insulation of Chinese doors

One of the main features of split doors is that a spatial frame is already built into them. Therefore, insulating such a Chinese door will take much less time and effort, since preliminary preparation they don't require it.

In this case, professionals use expanded polystyrene foam. Before its appearance, polystyrene foam or stone wool, but we encountered a problem - over time, the material gains moisture and becomes colored. This material is still used today, since it is cheaper than expanded polystyrene.

Before proceeding directly to insulation, it is necessary to remove interior lining doors. Often it is glued or screwed with self-tapping screws. If so, find the attachment points and unscrew them. The glued sheathing will have to be cut out, but it will not be possible to install it back, since it will be unusable.

Pre-cut pieces of polystyrene foam must be glued inside with special glue. You can purchase it at a specialty store or make it yourself. Make sure that there are no gaps between the material.

The top is covered with a pre-prepared fiberboard sheet. It must be secured with self-tapping screws to the door base.

Removing the trim

The very first thing you need to do when you start insulating a door with your own hands is to get rid of internal material. Of course, try to do this as carefully as possible, but if for some reason the canvas is damaged, do not be upset. Anyway, later you will replace the coating with chipboard. This way you will even save your time.

Insulation of the box

In order to retain heat in the room as much as possible and prevent various types of dust from entering the room, insulation of one sheet is not enough.

Many people make mistakes and ask this question after all the work has been completed. If this situation has already happened, then you need to make holes in the box and fill the gaps with granular insulation or polyurethane foam, but be extremely careful.

Alternative methods

In addition to polystyrene foam to insulate a Chinese entrance door, you can use other materials. These can be ready-made, commercially available insulation materials.

Installation, as a rule, is carried out along the entire perimeter and is fixed with leatherette strips. After installation, be sure to check the entire area for gaps, joints, cracks or holes. They shouldn't exist. You can eliminate them using improvised means (foam rubber or leatherette).

What to do with one-piece fabric

It would be very convenient if doors from Chinese manufacturers initially had a layer of insulation. But since this option helps us save money, we prefer to fix the shortcomings ourselves.

In the case of an integral leaf, it is necessary to modify the inside of the door and install a new lining.

All work takes place in several stages:

• the entire internal part is completely eliminated;
• another frame is pre-created;
• Self-tapping screws are screwed into the wood and secured with a layer of putty. After which they are painted or varnished.
• Now you can start direct insulation. All material is fixed with glue.
• all this is covered up chipboard sheet, which must be measured and cut in advance;
• All that remains is to apply a layer of foam rubber and cover it with leatherette.

Keep in mind that after sealing, the dimensions of the door will become much larger, so you need to prepare the appropriate fittings in advance.

Insulation of Chinese metal doors with liquid filler

Craftsmen often use liquid fillers to insulate a door with their own hands. But to ensure that the material does not crumble, it can only be used if the seams are sealed. Care must be taken as there is no guarantee that you will be able to completely fill the space. And this is one of the most important points.

Required materials and tools

In order to efficiently insulate a metal door at home, we need:

• insulation material;
• drill;
• liquid Nails;
• foam for installation.

These are the most basic tools without which you cannot get started.

Stages of work execution

The procedure required to insulate a Chinese door:

• remove the doors from their hinges;
• remove all locks and peepholes, if any;
• remove all contents from the inside of the canvas;
• fill empty spaces with insulation and secure with glue;
• check for cracks;
• return finishing panel to the starting position;
• install the peephole and locks in their places.

If you follow these simple rules, warmth and comfort in the house is guaranteed to you.

Conclusion

Installing and insulating a Chinese door yourself is great way savings.

At the same time, by correctly performing each described action, you do not lose anything in quality for low price. The materials needed for the work are available in every home and do not require special training.

The door plays one of the main roles in the house, because the reliability and strength of the door is the key to the safety of the house. But in addition to the reliability of the door, you need to remember that in winter, if the door is not insulated enough, cold air currents can pass through it, so insulating the house is also a very important process.
How to insulate a Chinese iron entrance door is probably of interest to all apartment owners, and especially owners of private houses.
What materials do Chinese door manufacturers use for insulation? Whatever materials are used for door insulation, they will always be mounted between the frame and the sheathing sheet. Most often, Chinese door manufacturers use materials such as polystyrene foam, felt, mineral wool and many others to insulate these doors.

Nowadays, foam has also been very actively used as a material for insulating doors. Some Chinese door manufacturers also occasionally use concrete or pine sawdust to insulate doors.
The main thing that all these materials have in common is that they all must completely fill the space between the vast sheet and the frame, so as not to give any air access to this void at all.
Corrugated cardboard- This is generally one of the most popular materials for insulation, but this material cannot cope even with slight frosts.
How to insulate a Chinese iron entrance door with your own hands and whether it is even possible is a rather interesting question. Photo of corrugated cardboard below:

Yes, you can do it yourself and it is done as follows. In order to insulate the door made in China First you will need to select the appropriate material with a thickness of approximately 2 centimeters. As additional insulation can be used a metal sheet. Before you start making insulation, you will need to remove the doors from their hinges, and then lay them on flat surface. After this, you will need to completely remove all the fittings from the doors. The door trim begins along the edges of the door.

They eliminate the possibility of drafts as they will completely close the gaps that form between the frame and the door. Then you will need to cut out the corresponding strips, usually 14 centimeters in size, from the upholstery material.

These strips will need to be attached front side down to the edge of the door. You will also need to indent from the edge of the door by 1.5 centimeters. Then you will need to make rollers from mineral wool, which will have a thickness of about 3 cm. They will need to be laid on the already nailed dermantine strips, then completely turn the strip and attach it to the edge of the door.

After all this is done, the door will be well insulated and will be able to withstand severe frosts.
