How to insulate the wall in the apartment from the inside and outside?

Today, when choosing housing, the primary criterion is comfort. Modern construction technologies allow construction of facilities with energy-saving elements. This indicates that the thermal insulation in such structures is at a sufficiently high level. However, today not all residential buildings have such qualities. This is due to the fact that new technologies began to be used just over a decade ago. To ensure a comfortable stay, the owners decide to insulate the walls with their own hands. Next, we'll figure out what the process is. Also, the article will tell you the better to insulate the walls of the house.

General information

Almost all specialists agree that if the question is: "Do you want to warm the wall in the apartment from the inside or from the outside?", It is better to give preference to the second option. If the room is located above the third floor, moreover, in addition to this corner, then you will have to use the first method. It should be noted here that if you insulate the wall in the apartment from the inside, then immediately reduce the useful space. This is due to the fact that the insulation layer has one or another thickness, in connection with which it takes some place. In addition, little to know how to insulate the wall in the apartment. It is also necessary to remember that it will still have to be finished. As a lining, for example, you can use:

• Plaster.
• Decorative panels.
• Plasterboard sheets.
• Tiles and stuff.

Possible problems of isolation

Internal insulation of the apartment has a number of shortcomings. The external temperature is of great importance in this case. For example, at -18 ^o C, freezing of concrete surfaces is noted. Gradually the ice begins to act on the insulation. This significantly reduces its operational properties and physical and technical characteristics. As a result, the entire insulation system ceases to work effectively. At a temperature of 0 to 10 between the heater and the wall will accumulate condensate. It also has a very negative effect on the quality of insulation. These problems can be avoided. Next, figure out how to warm the walls.

Key recommendations

To achieve the efficiency of the entire insulation system, it is necessary to adhere to some basic rules. First of all, it is necessary to create a qualitative layer of vapor barrier. It will prevent the accumulation of condensate in the gaps between the heater and the walls. Another condition for ensuring reliable insulation is the creation of high-quality ventilation. It will help remove moist air from the rooms, at least part of it. If there is insufficient ventilation, condensation will accumulate in the corners. Subsequently, fungus and mold will appear in these areas. In the very same room it will be stuffy and damp.

Material selection: basic information

Many owners of living quarters decide to conduct work independently, without consulting with specialists. At the same time, many for obvious reasons try to save money and choose the cheapest materials. In addition, not everyone knows how to properly insulate walls, so they do not work on technology. This leads to numerous mistakes. Before you warm the wall in the apartment, you should find out some of the nuances associated directly with the materials. All isolation is divided into groups. Each of them corresponds to one or another material from which the structure is erected. For example, for a brick wall, insulation is used, which can not be laid on concrete. An example of the use of materials for different surfaces can be considered here. For a brick wall, foam expanded polystyrene is perfect . This material has excellent performance properties and physical and technical characteristics. For a concrete wall, extruded polystyrene foam is more suitable. It is also an excellent insulation. For concrete surfaces, any other material, on one side of which there is a vapor barrier layer, is suitable. For example, as it can act as a foil. The vapor barrier layer should be on the inside.

The most common types of insulation

On the market today is a fairly wide range of materials. Most of them meet the most modern requirements of isolation. Warming the wall in the apartment from the outside can be many materials. But to isolate the room in the options are not so many. In fact, many materials can be used both inside and outside the building. The most common are the following:

• Mineral wool.
• Styrofoam.
• Warm plaster solution.

How to insulate a brick wall?

There are expensive and cheap materials. Among the available should be allocated foam. This material perfectly combines quality and relatively low cost. Interested in how to insulate the wall in the apartment? First it must be plastered. After the solution has dried, the surface must be leveled. For these purposes, putty is used. It can be stacked in one layer. After it dries, before insulating the walls with foam, it is necessary to arrange a waterproofing layer. It is necessary in order to prevent the accumulation of condensate on the thickness of the heater. Despite the fact that the foam has moisture resistance, over time, while staying in a moist environment, it can begin to decay. A layer of waterproofing will prevent this phenomenon. Before insulating the walls with foam, you need to prepare a solution to fix it on the surface. As a rule, a special glue mixture is used. The solution is applied to the wall. After that, the material plates are laid back and forth. It is necessary to make sure that there are no gaps between the elements. If the insulation is laid from inside the room, the final stage will be a vapor barrier device.

Mineral wool

Many owners of living quarters are interested in what is better to insulate walls from the outside? A good option is foam. However, some experts recommend the use of mineral wool. Despite the fact that the installation is more difficult, according to some masters, this isolation is more qualitative. Minvata is also used for indoor insulation. However, some experts do not recommend plastering surfaces when laying this material. Next, let us take a closer look at how to insulate a wall in an apartment with mineral wool.

Stacking technology

Now we need to tell you how to insulate the wall in the apartment with mineral wool. For this, it is necessary to build a crate. It consists of racks stuffed to the surface vertically. Elements must necessarily be set according to the level. In interstitial space, waterproofing is laid. It is attached directly to the slats. After that, you can lay the insulation itself. To prevent the appearance of "cold bridges", linens or slabs of mineral wool are installed end-to-end. Minvata must enter tightly, there should be no gaps. As a rule, for ease of operation, the slats are packed in steps that are slightly smaller than the width of the slabs or rolls. The final stage of internal insulation of the room is laying the vapor barrier. This material is again fixed on the slats. If it was decided not to plaster the surface, then it is better to lay the mineral wool in two layers. So isolation will be better.

Stucco solution

This method of insulation is used for a long time. In many residential areas, the plaster solution is used as insulation even today, despite a large number of more modern materials. The advantage of using the mixture can be considered worked out to trifle laying technology. If this option was chosen, then you should know some nuances.

Features of applying the mixture

First of all, remember that the warm plaster is applied in three layers. The first stage is splashing. In this case, a liquid solution is applied to the wall surface. This is necessary in order for the mixture to fill all the cracks and cracks. Throwing mortar on the wall should be carried out evenly and with effort. The layer of the spray should be 5-10 mm thick. The second step is priming the surface. If we evaluate the layers in importance in terms of thermal insulation, then the soil is considered to be the main one. Its thickness is 50-60 mm. Primer should be applied in 2-3 layers. Each of them should be 20-30 mm thick. This method of application is used to prevent the detachment of soil from the surface under its own weight. The third, the final stage, is the covering. Actually, it can be called the finish. The thickness of this layer is 3-5 mm. It is necessary to completely level the wall. The mixture is simply rubbed into the wall and creates a flat surface.

Insulation of concrete base

Above given options for the insulation of brick walls. But today most of the structures are made of concrete. What is better to insulate the walls from outside in this case? Actually, the material is used the same as described above. The technology of isolation arrangement is also not very different. However, when talking about the fact that it is better to insulate the walls of a house of concrete, experts recommend giving preference to expanded polystyrene. This material is more suitable for such a surface than, for example, minvate. If polystyrene is selected, the surface should be ground beforehand. Preferably in two layers. The wall should be as level as possible. All obvious differences should be removed. Then put a primer on the dry layer of putty. It will increase the adhesion of the surface with waterproofing. All other actions are similar to those for a brick wall. Instead of mineral wool, you can use more modern materials with higher performance characteristics. To them, for example, you can include cork panels. They are perfect for warming the room from the inside. However, they have a significant negative - high cost. If the insulation is used mineral wool, then it is recommended to stack it in three layers. The technology of material mounting is already described above. In general, the insulation of a dwelling is not accompanied by special difficulties. Particular attention should, however, be given to steam and waterproofing.
