How to insulate an iron Chinese entrance door: technology and materials. How to insulate a Chinese iron entrance door Insulation of a Chinese entrance door

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

We insulate a Chinese door

As usual, craftsmen quickly got their bearings in the situation and found ways to insulate the Chinese door leaf to preserve precious heat in the house. It turns out that if you have a minimum 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, doesn't it?

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

Insulation of split doors

This type of canvas has an internal lining that is attached to the frame using self-tapping screws. There are models in which the interior lining is completely absent.

On initial stage It is important to choose the right insulation. It is completely wrong to think that polystyrene foam or mineral wool is the most best option. It is much more forward-thinking and more profitable to take polystyrene, which initially has a denser structure.

Next, you need to establish the thickness of the insulation and its area, for which you need to measure the thickness of the fabric, not leaving out the sheathing on both sides. The area is established simply: the height of the door is multiplied 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 is then used to cover the insulation itself.

Once all this is in place, you can begin the process itself:

We remove the inner lining or cut out a new one from hardboard or other material.
If you are going to personally make the inside of the canvas, you need to carefully check all the dimensions and prepare holes for the handle, locks, peephole and other elements.
Any metal door has stiffening 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 fixed using liquid nails.
We screw the previously removed casing or install 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 rib and on all sides of the door leaf. If due to design features stiffening ribs it is impossible to screw fasteners into them, you need to additionally install corners.
The final stage of insulating the door for the winter will be a thorough grinding of the fiberboard lining, which is done with sandpaper or a fine file.

What to do with one-piece fabric?

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 where the entrance door structure has one-piece panels, you need to be prepared to change internal view 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 strips are fixed along the entire internal contour of the canvas 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 prepared in advance in the metal base, and their diameter will be slightly smaller than the circumference of the fasteners themselves. At this stage, it is recommended to secure several cross slats, 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 everything wooden parts must be painted or varnished.
Then the Chinese door is filled with the selected insulation, which it is advisable not only to press well and squeeze 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 self-tapping screws or even nails to wooden planks.
Foam rubber is placed on top, onto which high-quality leatherette is stretched. The latter is attached with specific nails with decorative or hidden caps. The entire process can be followed in more detail via video.
Since after such insulation of the door leaf it becomes much wider, it is important to buy the appropriate fittings.

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

Alternative methods

If you decide to protect a private house specifically 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 panel. Try living with two doors, between which there is a air bag. It has excellent sound and heat insulation abilities, and is quite capable of replacing one-hundredth of hand-made insulation and preserving a metal sheet from freezing.

The 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. Due to the minimum decorative requirements, taking into account the place of use, the insulation of a 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 the painstaking work is 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:

The bolts holding the hinge strips are unscrewed on the canvas and the sash is disconnected.
It is placed on a table or other elevated surface for the convenience of subsequent manipulations.
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.
After practicing on convenient location When cutting tacks, you should do this along the entire contour.
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.
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 lay a wooden beam around the perimeter inside the canvas, 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 is electrified and flows to the walls, it will have to be compacted with a wooden strip 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.

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 a Chinese-made door, you will first need to select the appropriate material with a thickness of approximately 2 centimeters. As additional insulation You can use 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.
