The question of how to insulate the walls of the house from the outside, come at the stage of forcing out the frame of the house or when finishing the already finished construction. There are a lot of materials, some cheaper and more affordable, others have to spend an impressive amount of money.
Types of insulation for the house outside
First of all, we will determine what kind of material you prefer. We will choose it according to several criteria:
- the value of the thermal conductivity coefficient directly affects the thickness of the insulation layer, which will be sufficient for the structure;
- the service life is also affected by the moisture absorption coefficient (the higher this index, the faster the material will become unusable);
- density and combustibility class will affect the weight of the structure and its safety.
So, according to these indicators, we will choose the most suitable type of insulation. All materials used today are conventionally divided into two categories.
- Inorganic heaters.
- mineral wool is one of them. Popular raw materials due to their noise-insulating properties, their ability to breathe. Minvata does not burn, but there is a possibility of the appearance of rodents. It absorbs very much moisture and after that loses a good part of its heat-insulating properties, and in the future completely never dries up;
- polystyrene opposite very little absorbs moisture, but it does not breathe. Before you warm the house from the outside with polystyrene, you need to carefully consider the installation of the supply and exhaust ventilation system;
- stronger extruded polystyrene foam , just does not breathe. A major drawback is its ability to burn and at the same time to release toxic gases;
- the most fashionable material is considered to be so-called warm plasters. The composition of the mixture includes foamed glass balls, which fulfill the task of thermal insulation. It does not burn and air passes, it is always possible to repair damaged areas.
- many believe that warming the house from the outside is better than natural materials, since it is much safer for health. In this regard, the plug fits perfectly. She will not allow the appearance of mold or fungus, but it burns well. The truth and cost of such pleasure is high;
- so-called cellulose cotton wool breathes no less well and prevents the appearance of mold fungus. It is worth remembering that this material absorbs moisture well, so when warming the house it should be completely covered with insulation;
- hemp and straw belong to the ecological class of heaters. Both materials breathe well, but they burn and absorb moisture.
How to properly insulate the house from the outside?
After the material for insulation is chosen, you can go to the question of the method of wall sheathing. Insulate the outside as a brick house, and a carpenter, you can in three ways. The first is the most traditional: these are three consecutive layers of a metal frame, a heater and cladding. To do this, first attach the profile to the walls of the house. Then a layer of insulation is placed in it (usually using a mineral wool, ecowool, stone wool). Then all this is lined, thereby protecting the insulation layer from weathering factors. The vented frame has a gap of a couple of centimeters between the layer of wadding and the cladding, which makes it possible to remove steam and moisture.
In order to insulate a brick house from the outside, a well is used, as this is the most reliable option. In this case, extruded polystyrene foam, expanded clay or other materials that do not absorb moisture.
Fashionable today, the wet facade is suitable for brick, concrete and block walls. From heaters use cotton wool, straw with hemp, a cork or dry algae. It is glued to the wall and plaster is applied from above.
Many today decide to insulate the house from the outside with siding, as this is a relatively inexpensive and reliable option. As a layer, foam, wool, extruded polystyrene foam is used. To properly insulate the house from the outside, as carefully as possible choose a plastic, because of its quality will depend on the service life.
