How to insulate a Chinese iron entrance door video and step-by-step guide

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 are of 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.

Material selection

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 an affordable price. This is the best option for a country house or cottage.
2. Soft. These include glass wool and mineral wool. This is an environmentally friendly and fire-resistant material. Designed for entrance doors in apartments and small spaces.
3. Inflatable. For example, polyurethane foam. The main difference is high cost and decent quality.

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

Dismantling the door frame

A metal door frame is a frame that is secured to the wall with metal pins or anchor bolts. If bolts were used for fastening, you can try to unscrew them with a wrench. But usually the fastening of the old door has long since rusted, so it is hardly possible to dismantle it without an angle grinder.

You will need to very carefully cut down the existing pins or anchors. When access to them is difficult, you will have to knock off a little of the concrete wall. Then, using a hammer and a crowbar or crowbar, we tear the box off the concrete. After this operation, it usually gives in easily and is removed from the opening.

We do the same thing if the metal frame of the front door is welded to the fittings driven into the wall. Using a grinder, we cut off the fastening rods around the perimeter of the box on which the structure is secured. For this reason, you often have to knock out a hole in the concrete with a hammer drill so that the grinder can fit in there. And then we manually remove the remnants of the reinforcement and pieces of plaster that hold weakly.

Typically, between the door frame and the wall there is a seal - a layer of polyurethane foam. To free the door, you need to cut the old seal with a knife. Residues that have not been removed can be treated with coarse sandpaper. Metal pins remaining in the doorway are usually not removed, since part of the wall can be destroyed along with them. Just when installing a new door, its fastening should be positioned slightly higher or lower than the old one.

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 they do not require preliminary preparation.

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

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 the internal appearance of the door leaf 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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Since after such insulation of the door leaf it becomes much wider, it is important to buy the appropriate fittings.

At the final stage, it is important to fill with foam all the 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 home 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: don’t rush to get rid of the ancient entrance curtain. 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 self-made insulation with hundredths and preserving the metal sheet from freezing.

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 the finishing panel to its original position;
• install the peephole and locks in their places.

If you follow these simple rules, you will be guaranteed warmth and comfort in your home.

Possible insulation options

The choice of material is an important point in increasing thermal insulation. Do not forget that insulation is directly related to the quality, strength and technical characteristics of the material. The higher the indicators, the warmer and quieter it is in your apartment.

Cotton wool is the most unfortunate and rarely used insulation option. It is environmentally friendly, affordable, and affordable in terms of delivery. However, in turn, it has major disadvantages - it is afraid of humidity, quickly absorbs particles of water from the atmosphere and is flammable.

Mineral wool insulation - needs additional waterproofing

Mineral wool and its varieties have high insulating properties and are an environmentally friendly material. However, it requires additional expenses for the waterproofing layer. The hygroscopic structure favors the absorption of moisture from the outside.

Foam plastic, penoplex, expanded polystyrene - they are lightweight, have high technical characteristics and will reliably serve for many years. The best options as insulation, hydro- and sound insulators. In addition, they are affordable and are not afraid of high humidity. They will last for decades. The only negative is that it is subject to mechanical damage, the structure is damaged and may crumble. Therefore, it is recommended to cover the seal on top with a layer of hardboard or an MDF panel.

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 a more economical method and simply stick a silicone foam or rubber seal around 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.

The outside doors of apartments are upholstered with vinyl leatherette, leatherette or natural leather, having previously been insulated 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.

In order to isolate the room from extraneous noise, it is recommended to install well-insulated interior doors and cover the walls with special soundproofing panels.

External sound insulation

It can be produced using vibration and sound insulating materials on an adhesive basis, as well as using durable glue or liquid nails. Polystyrene, vibroplast, bitoplast, bimast can be used. We degrease the surface of the door and glue the self-adhesive sheets with smoothing movements. Or we evenly distribute the glue and liquid nails and fasten the sheets of material in the same way. Carefully cut off the excess with a mounting knife. Smooth the edges and, if necessary, glue the lagging parts. It is advisable to paste the inside and outside of the door.
