Recently, every year there is an increase in electricity tariffs and heating. The owners of houses and apartments take all possible ways to reduce heat loss - insulate the walls, roofs, floors and foundations, put double double glazed windows on the windows, etc. But most of them do not take into account the fact that through a displeased door leaves 5 to 10% heat. And if the old windows can be replaced with modern, then the door replacement will cost much more expensive, therefore it makes sense to think about the insulation of the already existing design. It is about this that we will talk in our article and tell how to insulate the entrance door without much cash costs.

General recommendations
Since it is recommended to cook sleeves with the warmth of the house or the apartment with the summer, warming up at home or apartment before the start of the rains and the first frosts. According to research, if you make high-quality thermal insulation of a simple inlet door, then the temperature indoors will rise from 3 ° C to 5 ° C. This seemingly minor difference can become a decisive factor - you will not need to walk in your own house, loyering into a sweater or blanket, you will become less ill, the microclimate in the room will noticeably improve.
The insulation of the entrance door will not only reduce the cost of heating and to get rid of the drafts, but will also make the "face" of your apartment more beautiful and reliable. Today, all developers are put into operation apartments in high-rise buildings with metal entrance doors. Apparent at first glance reliable and strong, such a design is an ordinary tin, which is often often jammed by a cans.
Is it worth saying that a sense of security does not inspire such an entrance door, but there can be no speech about any insulating qualities. Through it, you will clearly hear what is happening on the landing, the metal cools very quickly and skipping the cold inside the room, and from drafts such a sheet of iron will not protect.
The thermal insulation of the door guarantees not only cold protection, but also provides good noise insulation and increases the strength of the door canvase. If your home has a plastic entrance door, then special tools and knowledge will be needed for its insulation. But since in most cases we have to deal with wooden and metal doors, we will focus on them. To cope with this work under the power of any owner or hostess who know how to handle the elementary "household" construction tools - a hammer, a screwdriver, hacksaw, etc.
Before starting to work, it is necessary to take into account the specifics of the material from which the door is made. So, for example, wood is rather soft, it is easy to work with it, but, on the other hand, it is because of its "fattyness" there are bridges of cold. When the temperature is dropped outside, the wood is compressed, it becomes more dense, and the resulting gaps are formed, even if the door block is fitted very precisely.
There is enough gap a couple of millimeters in order to significantly increase the heat loss of the apartment and deliver the residents a lot of discomfort. And the colder will become the atmosphere outside, the stronger the wooden door will shrink, respectively, the gap will become more. We will tell you a little later about how to insulate the wooden door, but so far we will talk about metal structures, as they are most common in modern cities.
If you are "lucky" to move to an apartment with an entrance door made of a bare tin, then the heat-insulating work must be started immediately without hoping that the cold will not reach your flood. If the apartment is on the first, second or third floor, the insulation should be as high quality as possible, because the whole cold from the street will go from your door.
Of course, you can change the iron door to the warmed, and many are advised to do, without bothering themselves to understand the details. A good warmed metal entrance door is worth a decent money, but even a multivalued number on the price tag does not always guarantee quality. If you look at a standard insulated door in the context, then its structure will unpleasantly surprise with its elementality - this is the usual "sandwich" from steel sheets outside and insulation inside. And by what thermal insulation material is in the middle, the protective characteristics of the door depend. In low-cost doors there are foam plates of a small thickness (the cost depends on the thickness of the insulation). In better models there is a foam, extruded polystyrene foam, mineral wool and other materials.
Steel door
The insulation for the doors can be any, and the main defining factor here are financial capabilities. The optimal option for the apartment in a high-rise building will be foam. Even if you buy the thick plates, it will cost much cheaper than changing the entire door, especially since you will need only a few pieces. For fixing foam, it is necessary to use special glue.
Step-by-step instructions for the insulation of the metal door:
- Remove the door from the loops. To do this, slightly enclose it, put the mount between the floor and the door and the unlock presses on the improvised lever raise the cloth. Remove the door will be fully operational only in open form, otherwise it will strive in the upper crossbar of the box.
- Put the door to the floor or table, dismantle the removable protective sheet.
- Inside the door canvase, put a foam, lubricated with glue at several points. Before this, the plates of foam should be cut so that they are 0.5-1 cm there were more inner surface - this will allow them to be tightly kept inside.

- In most cases, thermal insulation material is not obtained to lay a smooth layer without cracks. Drink small pieces of foam to close them, it would be too tiring, for a long time and ineffective. It is much easier to blew the lumens by mounting foam.
- Install the removable door of the door to the same place and secure it.
But if the door canvate does not understand, then thermal insulation should be carried out in another way. This concerns the chinese doors boxes, which are fully in modern high-rise buildings. They are very cheap and have a presentable appearance, so many developers install them at objects. However, such doors do not understand, and they are not as simple as the rest. The only way to "get inside" canvases is to cut the outer leaf, then put it in place with welding.
How to insulate the unsolved metal entrance door:
- Remove the door with the loop in the method described above.
- Remove all adjusting accessories, including handles and locks.
- Scores around the perimeter of the inside of the canvase (which will be in the apartment) Lock a wooden bar with a cross section of 10 mm.
- In the resulting box, put the selected thermal insulation material (foam, mineral wool, polystyrene foam).
- Close the insulation insulation for the door. At first, attach it to the top bar and, tightening, come to the rest of the bars around the perimeter. You can nail with nails with decorative hats or ordinary brackets using a construction stapler. Attachments to put every 10-15 cm.
Useful advice: For greater strength and aesthetics, it is possible to make a frame from bars not only around the perimeter of the door, but also put the bars inside by making several cell compartments in which the insulation is located.
It should be borne in mind that such a door will take a little inner space of the room, but it will give warm in the cold season, silence and comfort.
Wooden door
Wood has always been valued for good insulation qualities and the ability to keep warm in the house. From the tree still build the warmest baths and strong houses. But for some reason modern entrance doors of wood are not happy with high thermal insulation characteristics. The fact is that for the manufacture of doors, ordinary wood has not been used for a long time - they are made from pressed chips and other woodworking industries. If you try to raise the entrance or interroom door in any apartment of Soviet buildings, it will be very heavy - much harder to any wooden design. This is explained by all sorts of impurities, polymers, pressing, etc.
But, be that as it may, today in many apartments there are entrance wooden doors, desperately needing insulation. Over time, such structures begin to sign on the loop, it is loosely closed, disappeared or even cracking. And before proceeding with the warming of the old wooden door, it is necessary to identify the reason for the appearance of drafts. If it is a crack in the canvas itself, it must be embedded with a putty or knock the peg of the appropriate size there. If the door saved, then it should be tightened or replaced with a loop on new ones. If the loop replacement did not help, and the door still does not clearly fall into the opening, it may be necessary to remove the objective interfering part with the plane.
Warming input door do it yourself:
- For thermal insulation works, a wooden door, like a metal, should be removed from the loops and put on a flat horizontal surface.
- Remove all accessories, including locks and handles.
- Around the perimeter cut out a shallow groove for scallop layouts.
- As a heater for the wood door, mineral wool can be used, thick foam, foam, etc. But it is still better to take a soft material so that the door from the inside looked more comfortable and aesthetic. Start a foam rubber on the door leaf (you can use wood glue or universal construction glue). Unlike the installation of the insulation in the metal door, here the material should not be glued exactly on the form of the door. Leave 2-2.5 cm of an empty place at the edges, so that after pulling the upholstery, the squeezes were smooth and beautiful.
- Think over the insulation tensioning the upholstery material by attaching it with decorative nails or with a construction stapler.

- To make the door more beautiful, stretch the brass string under the nails of the maternity string - so on the upholstery "selling" the drawing. By the way, it is very necessary to do standard diamonds - having killed more nails, you can weave a more intricate drawing.
Useful advice: For additional protection against drafts, adjust the sealing gasket to the bottom of the door - then the threshold will never blow.
Insulation does not help - what to do
If the thermal insulation does not work, and in winter you still feel the cold at the entrance to the apartment, perhaps the insulation was laid incorrectly, its quality leaves much to be desired, or he simply does not cope with the load. In some cases, the cold can penetrate the voids inside the canvas, which were not fully filled with the mounting foam, so do everything as much as possible, then not to disassemble the door again.
Another reason for high heat loss is the wrong location of the door. Perhaps it costs a little crooked, and you need to pull the loops. It should be borne in mind that the insulation and the lamp for it give extra load on the accessories, so if you insulated the door in the summer, it can slightly squeeze. Be sure to use the rubber sealing tape to prevent the appearance of drafts.
From the door it will be cold, if the builders made a mistake when installing the door frame and looked loosely by the mounting foam. To eliminate this factor, bring the lit candle or lighter to the door and walk around the entire perimeter of the box - if the flame is dismissed, then the box is missing.
Double door
Sometimes the insulation of the entrance door can take away a lot of time and strength, and it is much easier to install the second door. For example, if you do not want to mess around with a unintended Chinese metal door, then putting the second web from the inside you will ensure reliable protection from the cold.
Even if the second door is made of the usual tree without insulation, it will still give its positive results. The heat loss will be reduced beyond the light that an air buffer zone will arise between the outer and inner doors, where the cold air will be delayed and heated. Thus, you will make a mini-pregnant, which will be your collateral of heat and comfort.
However, it should be borne in mind that the installation of the second door "takes" at least 20 cm of the inner space, but this is a reasonable victim in exchange for the absence of drafts. For good thermal insulation, you may not even need to buy a new door - you can take the usual interroom (naturally, without glass inserts). It is also recommended to install thresholds. The installation occurs according to the classic scheme, the only thing is to attach a seal or foam ribbon along the perimeter of the door.
If you want to make an apartment as warm as possible, significantly reduce the cost of electricity and heating, warm the entrance door, but do not stop on it - order the insulation of the facade, change the old windows and make warm floors.
