Often there are apartments in brick houses, which are cold even in summer. In winter, people dress warmly and still freeze. Heating bills are rising every month. Homeowners are starting to figure out why the heat doesn't linger in their home. They decide to insulate the walls themselves. The question arises of how and with what to insulate a brick wall from the inside. It is believed that there is nothing complicated in this. Many do not know that mistakes in work can lead to the fact that the walls will freeze through even more. Most often, the wall is insulated from the outside, but there are situations when it is possible to insulate the room inside. Such cases include the insulation of the end wall of a brick house from the inside. Let's consider this situation in more detail.
Cases when you can start warming
Insulation of brick walls from the inside is carried out only in extreme cases, when there are no other alternatives. These situations include the following:
- When the chief architect of the city forbade any changes to the facade of this house. It may be of cultural value.
- If a deformation seam was found between the houses exactly behind the desired wall.
- It happens that the apartment is located in such a way that there is an elevator shaft behind the wall. Then insulation from the outside will definitely not work.
In some cases, insulation from the inside is planned initially, it is prescribed in the project of frame houses. In them, if desired, you can enhance the insulation with the same material that was used during construction.
When the walls of the building are wooden, then insulation is possible only with one more layer of wood. If the owners of the apartment nevertheless decided to insulate the brick walls from the inside with their own hands, then this work must be approached with all seriousness. It is necessary to study the market for heaters, as well as find out how the installation work is carried out.
Features of the process of warming from inside the room
It is necessary to study the problems associated with the internal insulation of walls. Increasingly, people are wondering how to properly insulate the brick walls of the house. The main problem is that the wall begins to freeze even more with insulation. This is due to an increase in the level of dampness, and due to the loss of thermal insulation properties of the material used. As a rule, brick walls suffer the most damage.
In order not to aggravate the situation with the walls, you need to opt for materialswith low vapor permeability and minimal moisture absorption. During installation work with insulation, joints and seams should not be visible. Do-it-yourself wall insulation from the inside of a brick garage or other room should take place according to a pre-prepared work plan.
What materials can not be used?
There are a few restrictions. To insulate brick walls from the inside, it is unacceptable to use several materials:
- Mineral wool. Its properties do not allow it to be a good insulation from inside the house.
- Also not suitable for liquid ceramics and cork.
- Drywall, as well as warm plaster, should only be used at the final stage of insulation.
- Fibrous materials are also not suitable for insulation.
- Expanded polystyrene is not used in this type of work, as it does not fit well with walls without special solutions. Joints only reduce the tightness of the structure.
Insulation requirements
In order for the insulation process to be successful, the following criteria are followed:
- The wall must be dry at the time of work.
- Waterproofing work and vapor barrier must first be completed.
- The insulator must be moisture resistant.
- It is necessary to ensure that there are no joints and cracks on the heat insulator.
In order to meet all the conditions, you can build another wall inside the room. It can be tightly docked with the outer wall. Another option would be to haveair cavity and insulation layer. Due to these repair measures, the temperature in the room will become higher, but the area will be significantly reduced. You can lose from three to seven cubic meters.
Which materials are suitable?
There are several types of building materials to consider:
- Polyurethane foam is a material that creates an excellent moisture barrier. It has good thermal insulation properties. The only drawback in working with this coating is its application. Polyurethane foam is a foamy liquid, it quickly hardens. In order to ultimately get a flat surface, you will have to use formwork in your work. The space is filled with foam in small portions. It is important not to go beyond the edges of the intended border, the foam is very difficult to remove from the surfaces. After completion of the work, waterproofing is installed. This will require plastic wrap. It is fixed on adjacent walls, as well as on the floor and ceiling. Fasteners are wooden slats and sealant. It is permissible to replace the sealant with mastic. To carry out the final cladding, you will need an additional drywall wall.
- Second drywall wall. In this case, a thermal barrier is created by introducing heating elements into the second wall. Mounted by analogy with a warm floor. It is recommended to turn on this system only in extreme cold. The wall begins to warm up from the inside, and then the heat moves to the middle of the room. In order not to suffer the interior decoration of the house, a second wall of plasterboard is being built. A variant of the wall laid out is possibleone and a half bricks. In this case, the heating elements are installed on a false wall. This option maintains the temperature in the room well in cold weather, but has a minus. An example would be the insulation of a bath from the inside. The brick wall will act in this case as a second wall to maintain the temperature. The downside is the high cost of electricity. It turns out in parallel with the house, the street space is heated.
- Penoplex. This material is rarely used to insulate a brick wall from the inside due to its characteristics, which are not suitable for this type of work. Some still choose to use it. In this case, installation should be carried out carefully. Expanded polystyrene is sold in the form of sheets, their size is 100 by 100, or 100 by 50 centimeters. With any layout, joints will appear. It is important when working as tightly as possible to fit the sheets to each other. Apply a thin layer of sealant to adjacent sheets. The finished solution is applied with a spatula in the form of small "cakes". Insulation of brick walls from the inside does not imply the appearance of air voids. Condensation will accumulate in these air spaces. Over time, the wallpaper will be damaged, a fungus may appear on the wall. It is permissible to apply a special adhesive solution to the surface. It will provide maximum adhesion of the sheet to the wall. Before starting work, you must purchase a needle roller. It is excellent for perforating the material used. The solution will hold the foam on the wall more firmly. This method is only suitable for perfectly smooth walls. It is better to level the walls with ready-made mixtures. They arecreate a special layer that protects against moisture. Such material can later be used to renovate the bathroom.
It is possible to insulate a brick wall from the inside with foam. The desired material is advised to be fixed with profiles, in the shape of the letter "T". They are placed between sheets of foam and attached to the floor, ceiling. It is not allowed to fix the material with anchor bolts. They destroy the tightness of the coating. It is possible to insulate a brick wall from the inside with mineral wool, the technology of such a process does not differ from other methods. However, as noted above, this is not the best material.
In what order are insulation works carried out?
The first step to insulating a brick wall from the inside is choosing a method. After that, people count the amount of materials that need to be purchased. When everything is in stock, you can proceed with the installation work. After installation, cosmetic repairs are carried out using wallpaper, painting.
Tips for buying supplies
There are certain conditions for successful insulation. Don't waste money on materials. It is better to buy quality products, even if more expensive than we would like. You can not skip any steps in technology. It is necessary to write a plan of action in advance and strictly adhere to it. If at some stage you try to reduce costs, then in the future serious problems may arise. We'll have to re-insulate the walls. Need to spendwork in such a way that the invested funds and own strengths are justified.
When is the best time to carry out insulation work?
Insulation is done only in spring and summer. This work assumes positive temperature and no precipitation. Humidity should not go beyond the permissible limits.
You need to wait until the wall is completely dry. To speed up the drying process, you can use electric heaters or heat guns. Heat reduces indoor humidity as much as possible.
In what order are the walls processed?
The old coating is removed from the wall, even the bottom layer of paint or glue. There should be a concrete slab. It is cleaned of building dust using a vacuum cleaner or a regular brush.
If you notice a fungus on the wall, you can not continue to work without eliminating it completely. To combat fungi and mold, there are a number of drugs. They are applied to the surface, wait for a while and erased. Sometimes the fungus affects neighboring walls, they also need to be cleaned. It is better to use professional products, although many people still use folk remedies to combat the problem of mold and fungus on the walls.
Walls also need to be treated with an antiseptic solution. The next step is priming the surface. Between work, the wall should dry. When choosing a primer, you should pay attention to the composition. It is better to choose one that penetrates deep into the wall.
When is plastering done?
When heating elements are used in the construction, plastering work must first be carried out. The wall must be smooth. Plastering is better using lighthouses in the process. So you can achieve a flat surface, even if there were drops on the wall.
Plaster, applied even in a thin layer, dries for several days. This coating can be primed. After drying, a layer of sealant is applied. It provides a good water-repellent finish.
When the preliminary work is completed, go directly to the installation. After it, the walls are allowed to rest and dry completely.
An additional wall is mounted, after which the last layer of the finishing coating is applied. Wallpaper and paint are used as the final layer. Possibility of tiling. The most popular finishing option in our time is a special Venetian plaster. It turns out walls with artificial irregularities. Actual coverage under the "tight skin". Often an insulated false wall is made under an "artificial brick". This coating imitates natural masonry. It has proven itself in the market for being dust repellent and easy to clean.
When people choose high-density polystyrene foam, it can only be plastered. If the installation work is carried out with high quality, then it will last more than one year.
Nuances
It is important to remember about safety measures during installation work. It is worth taking care ofgloves, protective masks. It is necessary to carry out work in a ventilated area.
Conclusion
So, we found out how the walls of a brick house are insulated from the inside with our own hands. As you can see, you can choose different materials for insulation. The choice remains only with the owner.
