foam - thermal insulation material, which is most commonly used for insulation of facades of private houses and apartments, located in the "high-rise buildings."It has long been known fact: the house, the walls of which are not covered by any insulation, heat will give the street.Facade insulation foam is a quick and easy solution to the problem of heat loss from the room.

Advantages and disadvantages of foam
Any insulation material has its positive and negative characteristics.Foam for thermal insulation of facades - this is no exception.
The positive qualities of this material must include the following:
- in comparison with other insulating materials foam is much cheaper;
- has an excellent thermal conductivity;
- requires no vapor barrier;
- absolutely does not absorb moisture;
- resistant microorganisms;
- easy to assemble.
Negative points are:
- toxicity (In combustion emits acrid smoke);
- susceptible to damage small rodents.
As you can see, a lot more positive aspects than negative.This material does not deteriorate over time, not deformed, not break down as mineral wool, and does not change its dimensions under the influence of external climatic conditions
facade insulation foam at home - it is not difficult, the main thing to know the basic rules of this process and find the rightconsumables and tools.
Before we proceed directly to the purchase of material necessary to determine its amount.Make is not difficult, simply measure the area of the exterior walls of the house and on the basis of these parameters, calculate the required number of sheets of foam.
But in each case, this option may vary, as of this index depends on the zero point.It is important to calculate it.
for facade insulation of residential houses Experts recommend using thick sheets of 30-40 mm, for industrial facilities: 60 cm - for the walls and 80 cm - for the roof.
Important: if not properly calculating the zero point indoors will accumulate moisture, the result of this - mold, humidity, unpleasant smell.No less important parameter is also the density of the foam for insulation facade.
Wall insulation - the main stages
1. insulated wall.
2. adhered material (glue).
3. Ground profile.
4. Polystyrene plates.
5-6.Grid and dowels.
7. The primer layer.
8. The decorative layer.
facade insulation foam with your hands provide for the following stages:
- training walls;
- installation of ground profile;
- installation of insulation;
- plastering facade;
- applying a leveling layer.
In order to avoid any hitches, you need to prepare all the necessary materials and tools.For
need the following:
- polystyrene (EPS);
- primer for exterior use;
- glue for polystyrene plates;
- ground profile;
- reinforced mesh;
- Belleville dowels;
- spatula (smooth and notched);
- electric hammer;
- plastic float for grouting.
surface, which will be attached to the foam should be smooth and clean as possible.Differences flatness should not exceed 1-2 cm, and large bumps can knock down with a hammer, then carefully remove all the peel.Next you need a flat surface primed.For this purpose, any suitable mixture for external works corresponding to the type of surface.After the primer has dried, you can proceed to the next step.
Note: When using expanded polystyrene boards should be additionally prepared.This requires that their surface is slightly rough.This can be used for stationery knife or needle roller.Handle surface must be on the side from which the adhesive is applied.
Mounting Plinth profile
to the initial number of insulation was possible even before it is necessary to glue on the bottom front (around the perimeter) to attach the ground profile.In other words, it is - ground strap, which is intended as a basis for the first row of insulation and protection against rodents.Otherwise, the field mouse, extending into the insulation, foam will turn into dust.Therefore, to save at this stage should not be - it depends on the further operation of the design and its durability.
To install the metal profile is correct, the level of use.With this device around the perimeter of the house bounces "0" - the point from which to begin the installation plates.Affixing labels are connected by a cord otbivochnogo a solid line that using dowels 6x4 mm, and will be attached profile.
To slabs were laid flat and could monitor their verticality need across the wall, every 50-70 cm, set sag - nylon cords.For those who do not have this technology, it is suitable to control a sample of polystyrene plates for horizontal and vertical.
Sticking heater correctly
technology facade insulation foam means the foam sticking to the front and an additional Belleville fixing dowels.For gluing of foam to the surface of the walls is necessary to use a special glue for polystyrene plates.The next step - to attach the insulation to the solid adhesive layer.The adhesive is applied directly to the wall or on the stove heater with a notched trowel.
process should begin with a door and window slopes.After that, you must first stick the bottom row, which provides a horizontal ground profile.Plates subsequent rows should be fastened in a staggered manner (ligation joints).
After pasting the entire facade must also fix the plate with the help of disc dowels.
facade insulation - fasten foam plugs
hurry with this work should not be.Clay should dry up completely, and it is sufficient to 1 day.
dowels to score directly into the heater plate or in a corner, where several plates converge.The second option is more preferable, since one fixture will record just three slab foam.
Important: First plug must be positioned in the center, and the rest - in the corners of the plates.
If the installation polystyrene plates were gaps between them, they need to be eliminated.This is done to prevent the formation of cold bridges.If the gaps are not too great - it is possible to use a standard mounting foam.
In areas with a larger area is better in addition to glue pieces of Styrofoam cut.
After Styrofoam plates are secured with glue and dowels, the gap between the plates are embedded, you can start plastering.To mortar kept on smooth foam plates, first need to stick to them a special reinforced synthetic mesh.In the expansion joints of sheets it is necessary to impose a grid overlap.Adhesive mesh very quickly grasped, so it is important to have time to smooth the hands fabric before it is glued to the polystyrene plates.
After the entire surface is covered with a mesh, may be applied a first layer of plaster.This grid will be located inside the solution, but it should be seen slightly.Next, after the mixture is dry (but not completely), must be carefully wipe the surface of the grater or sandpaper.
After drying the first layer of plaster and then grout it is necessary to make a second layer.Optimum thickness thereof should be about 3 mm.Apply the solution should be small portions using a smooth trowel.Grout should be performed immediately after drying.It is best to carry out the work on individual sites to get done in time to grout.
Important: joints contractions should be placed at sites that are away from the joints reinforced mesh.
After drying topcoat can begin to color.For this purpose, any suitable paint for exterior use.Rational use of soft foam cushion.
advantage of this method is that with such a warming external walls there is the so-called thermos effect.This means that even in the cold season, and if there are problems with the supply of heat in the house will always be warm and comfortable.
in private firms that offer their services to the population, rates for thermal insulation of facades foam is not too democratic.But knowing the sequence of work, do the job and quite possibly yourself.
