Insulation of walls from the inside with plasterboard is excellentis suitable for creating an acceptable indoor microclimate, as well as for protecting it from factors such as dampness and drafts. It is worth noting that properly executed thermal insulation of walls significantly reduces the cost of heating the house. The insulating material is a shield that helps prevent the movement of air flows and provides the room with reliable protection from adverse effects of external factors.
Scheme of wall insulation with plasterboard. Insulation of walls covered with plasterboard has a number of advantages, among which are:
With the implementation of insulation of the sheathed wallsAlmost every owner can handle plasterboard. If you decide that you can do without the help of specialists, you should start by studying the technologies of wall insulation and choosing thermal insulation material.
Than to insulate walls from within
Insulation of walls from the inside is carried out with the help ofthe same materials that are used to insulate the external walls of the house. It should be noted that most specialists prefer to use mineral wool, polystyrene foam or mixed thermal insulation materials based on asbestos to insulate walls under plasterboard.

A little about the warming of the walls from inside under the gypsum board
Scheme of fastening plasterboard with glue.According to professionals, it is one of the fastest and easiest ways. As a rule, any technology has its own nuances, and insulation of walls covered with plasterboard is no exception. At least 3 cm should be left between the front surface and the rough wall. This is necessary in order to place thermal insulation material in the resulting voids. If the dimensions of the room in which the walls are to be insulated from the inside allow, the distance between the surfaces can be increased, this will allow placing more thermal insulation. The first stage of wall insulation is the installation of the frame. For these purposes, a galvanized metal profile is used. The distance between the structure and the wall should be about 2 cm. It is advisable to glue the guide profile with a special tape, thereby preventing its contact with the plaster composition. Next, mineral wool, foam plastic or other insulating material is placed in the cavity of the finished structure, which was formed by the rack profiles. After the thermal insulation is done, there remains on top of the frame. In case the room has a high level of humidity, it is recommended to choose a material that has such quality as resistance to moisture. Finally, the plasterboard is pasted over with wallpaper.

Mineral wool and its main advantages
Scheme of wall cladding with plasterboard onwooden frame. First of all, it should be noted that this method of insulating walls covered with plasterboard is distinguished by its low cost. Mineral wool is lightweight and elastic, which makes it much easier to work with. This material perfectly retains heat in the room. The only drawback of this insulation is hygroscopicity. In order to prevent condensation, it is necessary to provide vapor barrier. Penofol should be added to the main insulation material, this will protect the surfaces of the insulation from absorbing moisture. Such a vapor barrier as penofol also has thermal insulation properties. It is applied over the mineral wool already laid in the cavities of the frame. Penofol is a material consisting of foamed polyethylene and having an aluminum coating resembling foil. In addition to vapor barrier qualities, penofol is an excellent sound insulator. Due to its small thickness, the material practically does not take up space, and due to such a quality as flexibility, it is quite easy to install. Return to contents</a>
Penoplex as a heater of gypsum plasterboard walls
Scheme of insulation with penoizol.Very often, extruded polystyrene (penoplex) is used to insulate walls. This method is simple, so it is worth giving preference to it if you are faced with insulating walls covered with plasterboard for the first time. A special adhesive composition is used to attach the material. The glue is evenly distributed over the entire surface of the penoplex. The edges of the material have grooves that ensure its secure fastening. In order for this method of wall insulation to be as effective as possible, glue all the joints with a special tape. Self-tapping screws can be used for additional fixation of the foam. If you decide to insulate the plasterboard with your own hands using penoplex, it is not necessary to install a vapor barrier material. A feature of extruded polystyrene is its absolute resistance to moisture. Insulating walls with penoplex does not take much time and does not require the use of additional materials.

The process of installing a heating material by one's own hands
In order to insulate walls with plasterboard yourself, you will need the following materials and tools:
Types of plasterboard, areas of application and their color marking.
- heat-insulating material;
- sheets of plasterboard;
- profile directing;
- Rack profile;
- acrylic primer composition;
- plaster on gypsum base;
- sealing tape;
- dowel-nails;
- reinforcing tape;
- level;
- plumb bob;
- perforator;
- routing cord;
- Screwdriver;
- scissors for working with metal;
- a hammer;
- roulette;
- stationery knife.
Insulation of walls under plasterboard is carried outseveral stages. The technology usually depends on the material you prefer. The insulation material is attached in one of two ways: using a special adhesive composition, or by installing it in the frame cavity.

Other ways to insulate the wall from the inside
Many professionals prefer to performlaying foam plastic during the process of laying walls. During construction work, it is possible to use penoizol, it is used to fill gaps and other inaccessible places. Cavities under the slabs can be filled with cellulose. It is worth noting that the insulation has such disadvantages as flammability, susceptibility to mold, etc. In order to prevent such troubles, it is recommended to mix the material with a fire retardant and antiseptic agents before use. You can insulate the walls with ceramic insulation. This method is quite expensive, so it is not very popular. This material is a liquid paste that covers the walls, paying special attention to hard-to-reach places. The desired effect can be achieved by applying at least 5 layers of insulation. The undeniable advantage of such a paste is its durability.
