The insulation of the facade is considered an important process that can improve the thermal insulation parameters of the structure, as well as save on heating, which is considered an expensive element. For this process, completely different heater for external walls can be used, characterized by a parameter, price and appearance. However, the most popular is the use of polystyrene foam.
Ovaliating and characteristics of polystyrene foam
It is considered an ideal option for external use for various types of structures. It is available in the form of sheets that may differ from each other in size and density. However, when choosing this material, it is necessary to first pay attention to its thermal conductivity, since this property is of priority for insulation of the facade.
The main positive parameters of this material include:
magnificent thermal insulation parameters;
a low weight that simplifies both the transportation of the insulation and the process of laying it;
Available price that provides the opportunity to use the material to any person, regardless of the level of his income;
resistance before moisture, and this parameter is very important for external insulation, since there is always the possibility of precipitation to the insulation;
stability before fire;
High density.
The extruded polystyrene foam itself consists of three layers, and two of them are chipped slabs, and between them is polystyrene foam. You can use material not only for insulation, but even for various construction and finishing work.
The technology of insulation of the facade with polystyrene foam
It is initially important to purchase material in the optimal amount. To do this, make complex and correct calculations that can determine the number of sheets that can ensure the performance of all work without stops and delays. When choosing the material, its density should be taken into account, as well as the thermal conductivity and quality indicator. Sheets are not allowed on which there will be any visible defects or bumps.
After the preparation of the material itself and some tools that can be useful in the process of insulation, you can proceed to the procedure itself. It consists in several consistent stages, to which:
Surface preparation. It is initially important to check the facade itself, since it is not allowed that it has any pollution, irregularities, holes or other problems. When they are detected, it is urgent to eliminate all the shortcomings. This can be done in different methods, however, plaster or other mixtures are usually used. It is important to achieve the creation of an ideal surface, on which it will be possible to place sheets of polystyrene sheets without any problems. If there are minor transitions and cavities, then they can be left, since they will not be able to bring significant problems during insulation. It is best to pre -apply a primer to the entire surface of the facade. It not only contributes to the filling of the smallest hollows and irregularities, but also improves adhesion of completely different materials.
Direct gluing of polystyrene foam. This material can not only stick, but also be attached mechanically, however, for this, a special frame will have to be attached to the facade. If, however, work is used to align the walls in advance, then gluing the insulation is considered the most optimal solution with an even layer. Gluing is carried out in the end, as well as in even rows. It is necessary to start work from below, moving gradually up. The most optimal solution is in each even row the very first plate of polystyrene foam is cut in half in half, as this will allow you to form vertical and continuous compounds. It is necessary to apply glue during the work on the entire surface of the sheets, and the choice of glue is also considered an important issue, since it is not allowed to have a solvent in its composition.
All seams obtained in the surface should be good and carefully smeared with glue, which can be replaced by standard mounting foam.
Additional fixation of insulation. It is believed that exclusively gluing is not an ideal and effective means of fixing. Therefore, it is best to additionally apply umbrella dowel for each sheet of polystyrene sheet. This work should be carried out only after the glue completely and reliable drying, so it is usually performed a day after gluing.
Creating a reinforcing layer. The protective layer is originally formed using high -quality plaster, and so that it does not fall off the wall, the reinforcing mesh is attached.
Facing the insulated facade. Here you can choose absolutely any decorative materials that are well suited for a specific structure. Their choice depends on the financial capabilities of the owners of the house, as well as on the construction and preferences of the owners.
Thus, the process of insulation of the facade, in which polystyrene foam is used, is considered simple, and the choice of this insulation is a reasonable, appropriate and correct solution. If necessary, all stages are easily realized on their own, but here it is important to responsibly approach the choice of materials, as well as to each type of work.
