How to insulate walls from the inside in a private house from foam blocks?

Houses made of foam blocks are very goodheat-saving characteristics. However, in our Russian climate, additional buildings may require additional insulation. Like any other residential buildings, houses from this material are usually insulated from the inside. But, unfortunately, it is sometimes impossible to do this. Some owners of houses, for example, do not want for some reason to spoil their external appearance. It also happens that an unheated building is attached to the building, or in the immediate vicinity there is some construction, etc. In this regard, many owners of personal plots are concerned with the question of how to insulate walls from the inside. In a private house for this purpose, you can use different materials and this procedure is quite simple.

Types of insulators

The most popular types of insulation, used for plating inside the foam house, include:

• Mineral cotton wool. This can be a regular basalt insulator or less harmful glass fiber.
• Styrofoam. This material is worth more than mineral wool. However, the insulation with its use will cost, most likely, not much more expensive. The fact is that when using expanded polystyrene there is no need to install a frame. Therefore, it is quite possible to choose this material for insulation. But it should be taken into account that for health it is considered even more harmful than mineral wool.
• Polyurethane foam. This is the most environmentally friendly way to warm the wallsfrom the inside. However, such isolation will cost quite expensive. In addition, it is unlikely to finish the walls with their own hands with polyurethane foam, since special equipment is required for its application.

Which to choose?

The most popular type of insulationToday is basalt wool. It is made from a stone fiber impregnated with resins. Harmful this material is considered, because the latter includes phenol formaldehyde. Therefore, when buying mineral wool for insulation from the inside, you should pay attention primarily to its quality, and accordingly, to the brand. The most popular type of basalt cotton in our country is Ursa. This material has excellent characteristics and is quite acceptable. About how to insulate the walls from the inside in the private house "Ursoy", will be told just below.

Fiberglass wool is suitable for sheathing withthe side of the room is better than basalt. However, absolutely absolutely environmentally safe it can not be considered. Therefore, in this case, it is also worthwhile to acquire the highest quality material. It can be, for example, the same "Ursa", only fiberglass, or the popular "Izover", etc.

Styrofoam is worth choosing if the walls inside the room are very smooth and smooth. Install the slabs of this material usually in a frameless manner, on the glue.

What else will you need to purchase

The question of how to insulate walls from the inside inprivate house, comes down to including buying all the necessary materials. In addition to the thermal insulator itself, the owners who decided to cover the walls from within will have to purchase:

• Beam. It is necessary in the event that for insulationmineral wool is used. The width of the beam should be slightly larger than the thickness of the insulation. Calculation of the amount of necessary lumber is made taking into account the area of ​​the walls and ceiling, as well as the width of the insulation. When using foam polystyrene, you do not need to buy the bar. In this case, you will have to buy a special adhesive for the foam plastic.
• Reiki. They are necessary for fixing the vapor barrier.
• Steam Insulator. Penoblochnye walls - a material "breathing". Therefore, it is best for them to purchase not an ordinary polyethylene film, but a special membrane that transmits air.
• Finite matrix. In the event that the insulation will be made using a frame, it can be plasterboard, plywood or lining. Expanded polystyrene insulator is usually plastered or wallpapered.
• Consumables. And for mineral wool, and for expanded polystyrene it will be necessary to buy special plastic dowels with a wide bonnet.
• Antiseptic. Moisture of foam blocks, like air, is passed quite well. Therefore, in order to avoid the appearance of fungus and mold, the walls of them should preferably be treated with special means.
• Waterproofing. It is best if it is also an air-permeable membrane.

How to insulate walls from the inside in a private house: preparatory events

Before installing the frame or applying gluewalls and ceiling must be carefully dried. Also, all cracks and large chips should be filled up. Then the antiseptic is processed. Under the glue walls are usually primed. This allows to increase the adhesive properties of surfaces.

Warming with mineral wool: installation of a frame

After all the preparatory activitieswill be completed, you can proceed with the actual procedure for the insulation of walls and ceiling. When using mineral wool in the first stage, a wooden frame is assembled. Fix the timber to the foam blocks with self-tapping screws. In this case, it is best to take fasteners with a wide thread. Preliminary, the walls are covered with a waterproofing device.

Next, we will consider the actual process of howto insulate the walls from the inside in a private house with mineral wool. The distance between the fixed bars should be slightly less than the width of the purchased plates. It is best to install the frame elements vertically. Then the moisture accumulating beneath the finishing skin will flow unhindered downward.

Building a "cake"

So, now let's see how to insulatewalls from the inside in a private house. After the assembly of the frame, the actual installation of the heat insulator itself begins. Plates of mineral wool are installed between the bars of the vials, so that no cracks remain. In addition, they can be attached to the surface by dowels "fungi". Next, a vapor barrier film is stretched over the insulation on the beam. You can fix it to bars or slats. Tighten the membrane strips in a horizontal direction. Joints can be glued with scotch tape.

Finishing and ceiling lining

As you can see, the question of how to insulate the wallsfrom the inside in a private house of foam blocks basaltic or glass wool is reduced mainly to the reliable fastening of the beams and the accurate installation of the plates. Finish the installation of the "pie" plastering with plasterboard (fixed to a bar on nails or screws), plywood or lining.

When insulating the ceiling, the order of the insulation assemblyexactly the same. The only thing that fixes cotton wool to the surface with dowels or glue in this case is a mandatory procedure. In the event that the building has more than one floor, the ceiling is better insulated from above. The same recommendation experienced builders give and owners of houses with attics or attics. If the upper room is residential, two layers of vapor barrier film should be used for insulation. One is laid before the installation of plates of mineral wool, the second - after.

Use of expanded polystyrene

As you can see, to warm the house of foam blocks with the help ofmineral wool is quite simple. However, if someone does not really want to install a frame, you can choose polystyrene foam for insulation of walls and ceiling. Next, let's look at how to insulate walls in a private house from the inside with the "Izover" or any other foamy slab material.

When using this type of wall insulatorpre-level and primed. After that they need to be treated with an antiseptic and thoroughly dried. Styrofoam is fixed on the surface to a special glue. Apply it best with a roller on the bottom at the top. The procedure for the insulation with expanded polystyrene is as follows:

• Six plates are drilled in each plate. Two do it in the middle, the rest - on the edges. Drill holes in the wall.
• Then the insulated surface is greased with glue. For its application, it is best to use a roller.
• The plate is raised and pressed against the wall, holding it for a few seconds. The gluing is done in staggered order.

The final stage

The same technology is a great answer to the question ofHow to insulate walls from the inside in a private house with foam plastic. After all the plates have been glued, not too wide seams pass through the mounting foam. Large cracks - from 4 cm - are covered with strips of expanded polystyrene.

How to insulate walls from the inside in a private housepenoplex or isover? This question, therefore, is completely uncomplicated. Then proceed to mount the reinforcing mesh. To fix it, the foam polystyrene surface is coated with glue. Then drown the mesh into it and pass the wall again with the roller. Mount the grid so that the joints of its stripes do not coincide with the joints of expanded polystyrene sheets. After the glue dries, the walls and ceiling must be sanded. At the final stage, the surfaces are finished with plaster or wallpaper.

Finishing of expanded polystyrene

Stick wallpaper on the insulated walls can,probably, everyone. But their plastering is a procedure that has some of its secrets. First of all, you will need to purchase a special tool. Plain plaster will not lie on such walls too well.

If you decide to still use a simplemixture, you still need to pay attention to some of its qualities. Since the foam polystyrene is flammable, it is worth buying plaster with refractory properties. Also a very good solution is to buy a mixture that creates an air-permeable layer.

Stucco polystyrene, even insidepremises, it is possible only in dry weather. In the event that it is decided to finish the walls in this way, a special primer mix may be used instead of the adhesive for fastening the reinforcing mesh. After it dries (about 24 hours), the surface of the walls is also ground. To do this, you can use a piece of the same grid.

After grinding, a leveling layer 4-5 mm thick is applied to the walls. In a day it is also rubbed. Then the surfaces are primed again and the finish coat is applied (2-3 mm).

How to insulate walls from the inside in a private house on the second floor correctly

Warming of surfaces as described abovetechnology can be produced in any building from a foam block. This method is an excellent answer to the question of how to isolate rooms from the cold on the first floor, on the second, and so on. The most important thing is to buy high-quality materials and perform work with exact observance of technology.

As you can see, the question of how to insulate the wallsfrom within in a private house of blocks, is not particularly complicated and does not take too much time. It is quite possible to make all necessary actions for reliable isolation independently.
