Wall insulation for siding. Wall insulation technology. Materials

If you decide to use siding to decorate your home, then first you need to decide what material will be used.

Material selection

Insulation of the mineral wool wall for siding is a fairly common occurrence. But for this, you can also use polystyrene, extruded polystyrene foam, basalt insulation, as well as many other materials. After the material is installed, it is necessary to provide a space between it and the decorative layer, so that air can circulate freely, to prevent putrefactive formations and mold.

Wall insulation for siding can involve the use of polystyrene foam, it is affordable and practical, but it is not the most effective. You can choose a more modern kind of insulation, for example, expanded polystyrene. It is distinguished by production technology, and also has more outstanding quality characteristics. The material consists of cells that are filled with air, which makes polystyrene foam an excellent material. This insulation is safe for human health, it is much easier to install it than mineral wool, for which it is necessary to use gloves and a mask. Mineral wool for wall insulation can be dangerous for the builder at the time of installation. Another plus of polystyrene foam is its low weight, which allows you to carry out the work yourself. Among other things, the layer will not affect the walls and foundation of the house. The latter does not have to be strengthened, which reduces the cost of the process. Use material that has been flame retardant treated. This will eliminate the occurrence of a fire.

Preparatory stage

Insulation of walls for siding involves the need to prepare some materials and tools. First of all, you should buy glue intended for polystyrene foam. You will need fasteners, which can be a plate nail. In order to identify irregularities on the base of the wall, nylon cords should be used. After this, you need to take care of the presence of a screwdriver, building level, drill, as well as a hacksaw and office knife. You will need a spatula.

Specialist recommendations

If you decide to warm the walls for siding, it is recommended to do this in the warm season, when the temperature does not drop below +5 degrees. This is important for the reason that the adhesive, under other conditions, behaves unpredictably and is not able to provide a strong bond. In order to achieve a positive result and reliable fixation of the insulation on the wall surface, it is preferable to use two types of fasteners, among them - dowels and glue. In this case, it will be possible to obtain reliable insulation, which will last for more than one year.

Work on the adhesive mass

Before starting work, it is necessary to take care of the preparation of the glue, these manipulations should be prescribed in the manufacturer's instructions. Do not use independent recipes or be guided by personal opinion, since improper preparation of the adhesive can lead to poor-quality fastening of insulation material. Mineral wool for wall insulation, as a rule, involves the use of exclusively mechanical fasteners.

It is important to take into account several points, among them it can be distinguished that the glue must not be applied before installing the sheets, but in advance. This should be done about an hour before the material is supposed to be laid on the surface. If the facade is even, then the adhesive composition must be leveled with a thin layer over the entire canvas, while with a wave-like wall - with a spatula in the corners and central part.

Facade preparation

Insulation of walls for siding implies the need to prepare the facade. Any repair should begin by washing dirt and dust off the surface. After that, it is imperative to get rid of all unnecessary items such as protruding nails, pieces of reinforcement, as well as protrusions. If there is a need, then you can treat the surface with sandpaper, which will allow you to slightly level the facade. Those places where there are cracks and cracks on the walls must be putty treated, this can avoid unpleasant consequences, and also help to improve the thermal insulation qualities of the wall. The final step in preparing the facade is to apply a primer. In order for the facade insulation to be successful and effective in polystyrene foam , it is necessary to observe the sequence of works described in the article.

Due to the fact that wall insulation on the outside for siding requires in some cases the need for alignment, many home masters resort to savings. It consists in the use of a nylon cord, which must be lowered along the wall. This will reveal deep depressions and impressive ledges. If this moment is not taken into account, then the entire external side of the wall will be undulating after the installation of the finishing material. In those places where you have discovered impressive dips, they should be leveled with the help of an adhesive composition. It is necessary to impose a mixture in these places with a more impressive layer. If the protrusions were noticed, then they can be eliminated by using the hammer. The resulting irregularities need to be repaired with putty, in some places a method is used that involves cutting polystyrene foam. It will be much easier and faster, among other things, you won’t have to spend so much.

Installation of insulation material

The technology of wall insulation with expanded polystyrene suggests the need for the formation of inconspicuous seams. If impressive gaps are formed, it is recommended that they be repaired with liquid polystyrene foam or with individual pieces of polystyrene foam. However, do not use construction foam, since after solidification it will increase in size and affect the integrity of the entire structure. If irregularities were found when joining the sheets, then you can get rid of them with a grater or rough skin. It is necessary to use for mounting exclusively dish-shaped dowels, which are equipped with a special hat in the form of an umbrella. This fastener is able to effectively press the sheet to the surface. All steel fasteners, such as nails or self-tapping screws, will be ineffective. When using them, it is likely that a strong wind will deform the insulation material. After all the sheets of the heat insulator are installed, the places of plate self-tapping screws must be puttied.

Features of the work

When the walls are insulated under the siding with their own hands, it is necessary to attach a sheet of expanded polystyrene to the wall and drill holes for installing dowels. If there are irregularities, then you need to get rid of them with glue. Next, wait about an hour, then attach the glue-treated sheet to the facade and install plate-shaped fasteners. The fastening is initially necessary to carry out around the perimeter, only after the central part is fastened. After one row of insulation material is installed, you can proceed to the second. You need to start the installation on the left, gradually moving to the right. It is important to try to maintain the level during the work, it can be checked using the appropriate construction device. Until the glue has seized, it will be possible in some places to correct the position of the heat insulator, to add or trim it.

Laying insulation in two layers

Warming of wooden walls is rarely done using polystyrene foam, but if we are talking about brick walls, sometimes it becomes necessary to install the material in two layers. This may allow you to create a more effective insulation layer. In this case, the first layer does not need to be puttied, and all finishing work is transferred to the second. Fastening can be done without the use of glue, using only plate-shaped dowels, which must be selected taking into account the thickness of two layers. The installation of fasteners should be excluded in those places where it is already installed, otherwise it may be necessary to redo the work, and the holes will already remain.

Final work

After the insulation material has been installed, you can begin decorating. In this case, we are talking about siding. However, lining or plastering may be used. In the latter case, it will be necessary to further reinforce the surface using a plaster mesh.
