Warming of houses outside. Materials for insulation of the house outside

Western trends brought ordinary Soviet people not only beautiful and affordable ways of finishing the house, but also other advanced technologies. For example, insulation of houses outside. With this, you can save a lot on heating the house and get rid of annoying mold on the walls and dampness in the house. Basic requirements for insulation: availability, efficiency and ease of installation. In addition, the materials should be light to not heavily burden the foundation of the house. Unfortunately, not all materials for warming the house can combine the above qualities, so the market can find such a variety of insulation materials. We'll talk about them below.

Ways to warm your home

There are various materials that have high thermal insulation properties. But they are all attached to the walls on a similar principle.

Warming the house from the outside can occur in three ways:

• Thermal insulation material is fixed with adhesive mortar, and in the end plaster finishing is carried out.
• Creating a three-layer unventilated wall. A heater is attached with a special solution. After that, an external wall with a thickness of one brick is built. Between the heater and the new wall there must be an air gap.
• Ventilated facade is another option of how to make the insulation of a house outside. The wall is covered with waterproofing material, and a heater is attached from above. After the windshield is installed, and the frame is clad outside with a lining. By this principle, the house is insulated with siding from the outside.

Each of these methods has its own disadvantages and advantages. In addition, manufacturers fill the market with combined insulating materials, which require special installation technology.

How to choose a material for insulation?

All heat-insulating materials differ in their properties, installation method, price and durability. They are united only by a common purpose: they are all needed to insulate housing. Most often for insulation use: mineral wool, polystyrene, expanded polystyrene extruded, polyurethane foam, cellulose materials, basalt slabs and so on. Their main differences are moisture resistance, vapor permeability and thermal conductivity. The first two parameters play the role of dependence on climatic conditions, and the thermal conductivity is important in calculating the thickness of the insulating material. So, instead of stacking foam concrete in several layers, it is better to use foam, which is several times thinner, but has the same thermal conductivity.

Preparation of walls for insulation

Once the material is selected, you can safely proceed to the next step. Warming the walls of the house outside can not take place without their preliminary preparation. The old layer of plaster or insulation material is cleaned to the very base. At the finish line you will get a bare brick, concrete or wooden wall in front of you.

We clean the surface of dust and dirt and carry out a thorough priming. It is best to use solutions with deep penetration. If there are protrusions or depressions larger than two centimeters in size, they should be sanded or glued to one level with the wall.

After the walls have dried from the primer, we mount plumb lines and beacons, along which the insulating material will be laid. To simplify the installation, screws and anchors are installed along the edges, a string or line is tightened between them and the plumb bows. Thus, a strong mesh should be formed on the wall, which will serve as a guide for work.

Than to warm a log house?

It is recommended to use ventilated facade technology for its warming. So the walls will breathe, and the house will not get mold. Warming houses outside requires treatment of walls with refractory substances and antiseptics. Cracks between the logs are embedded with jute fiber or tape tape. Foam is also suitable.

Using vertical bars, the facade of the house mounted crate. Then lay the layers of vapor barrier and insulation. It is better to use a mineral wool or fiberglass. The heat insulator starts to be laid from below upwards, and after - fastened by dowels. From above on a heater a waterproof membrane is fastened , for this purpose it is possible to use a stapler.

At the last stage, the facing material is installed. In the role of which you can use lining, siding, facade panels and so on.

Than to warm walls from a bar?

The stages of thermal insulation of such a house almost do not differ from the wooden one. Nevertheless, there is one difference. The walls of the timber have a flat surface, so that the insulation of houses from the outside can be carried out using not only roll insulators, but also tile materials such as mineral wool and glass wool. The installation technique and all the steps are identical to those described above.

Than to warm a brick house?

The insulation of a brick house from the outside can be done in several ways:

• Ventilated facade. Thermal insulation of the room is carried out using plates of mineral wool or polystyrene. The material is attached to the walls using dowels or glue solutions. Then, the crate is made of bars or a metal profile. And then we rely on the scheme of thermal insulation of the wooden house.
• Easy wet method. This is the technology of multi-layer facade insulation. In the course are foam or a hard mineral wool. The material is attached to the walls using a glue solution or dowels. Rims are not needed here. The heater is attached to the heater, and two kinds of plaster are applied from above.
• Wellwork. This method is used not only for brick, but also for block houses. At the time of building the house between the walls is fixed heat insulation material and additionally laid vapor barrier and waterproof material. For the insulation of the finished building, it is better to use moisture-proof materials. These include polystyrene foam, polyurethane foam and others. If you want to insulate the structure with an air gap between the walls, you can apply a liquid heat insulator, which after a while will harden. In addition, the air layer can be filled with polystyrene foam. It, unlike mineral wool, it is easy to place in the inter-wall space.

If the insulation of the brick house from the outside did not bring the desired results, you should think about the insulation of the floor, roof and windows. It is the poor condition of these sources that contributes to significant heat loss.

Warming of foam plastic

One of the most cost-effective ways to keep the heat in the house - the insulation of the house from the outside with polystyrene foam. To start, the bottom of the wall is installed so-called shelf, it is necessary to align the first row of foam.

The material is fixed using dowels or glue. In order for the work to be smooth, use the sheer grid, which was mentioned above, and the level. For the density and stability of the structure, the next row of foam is stacked with a half-sheet shift (like bricks when laying). At the corners and around the windows the material is fixed with metal corners. After all the walls are covered with foam sheets, a plastic mesh is fixed on top and plaster is applied: starting, finishing and decorative.

Warming with mineral wool

The thermal insulation of mineral wool is very similar to that of cellulose and basalt slabs. To fix the mineral wool, use a frame structure and crate. It should fit tightly into the formed cells, leaving no gaps. Then, before reinforcement, a reinforcing mesh is fixed and plastering is carried out. Wall decoration can be of different types: siding, lining, brick wall, etc.

Warm insulation of houses outside with mineral wool is a great way to insulate your home and save on heating.
