A method of insulating walls inside foam

quality home insulation helps to save not only well, but also to increase comfort in the home.Insulated walls can be both outside and inside, especially if the funds for repairs are limited.There is an excellent way to 100% insulation of walls inside foam + video instruction, after learning that do all the work yourself is not difficult.

thermal insulation materialsquite a lot, but the foam is stable demand for more than a year

, thanks to its properties:

  • does not absorb water;
  • not exposed to molds and other microorganisms;
  • little weight;
  • easy to cut out and mounted;
  • environmentally friendly;
  • has low thermal conductivity.

    Comparative characteristics and advantages of using foam

have foam and disadvantages: it is damaged by mice, it is flammable, when combustion emits acrid smoke.To minimize the burning in the fire insulation layer, the insulation should be chosen with a high content of flame retardants and high density and to use only the incombustible materials as exterior trim.

conditions for thermal insulation of walls inside

There are certain conditions that can be performed inside the insulation, and when you can not.Improper insulation on the walls of the condensate acts, under a layer of insulation is developing a fungus, there is a gradual destruction.Condensation indicates the location of the dew point, and its occurrence depends on the temperature and humidity in the house.Determine the dew point will table:

Table dew point

also have value and other factors: the availability of the ventilation system, heating quality, operation mode of the home, the thickness of the load-bearing walls, region of residence.

On this basis, to carry out an internal wall insulation can be under the following conditions:

  • in the house permanently live people;
  • ventilation system meets the established standards;
  • heating system running smoothly;
  • insulation is planned for all surfaces;
  • walls always remain dry.

only the outer insulation is allowed in all other cases.

technology inner insulating walls

Inner insulation of the walls

technology inner insulating walls

warming process, though simple, but it requires careful preparation.First you need to calculate the number of sheets of foam, to prepare the tools and additional materials.Standard sheet sizes:

  • width - 1 m and 0.5 m;
  • length - 1 m and 2;
  • thickness - 10, 20, 30, 40, 50 and 100 mm.

For internal insulation foam is best suited 1x0,5 m and 1x1 m, 50 mm thick.Large sheets still need to cut out, and transporting them is not very convenient.To calculate the required amount of material, the floor area should be divided into one area of ​​the plate and add 10%, since when cutting insulation necessarily waste.

Additionally required:

  • mortar;
  • glue;
  • plugs-fungi;

  • waterproof coating;
  • reinforcing mesh;
  • plaster composition;
  • putty;
  • set spatulas;
  • sandpaper;
  • drill;
  • trowel;
  • level;
  • sharp knife.

Step 1: Clean the walls

Cleaning the walls

Cleaning walls

foam is attached to a clean, dry and smooth wall, so first dismantle the old coating.Wallpaper, decorative plaster, panel and other trim removed completely, but the paint should be removed only if there are cracks or delamination.If the wall is flat, completely whole, paint is very durable, you can immediately proceed to the insulation.

Step 2. Align

Plastered walls

Plastered walls

After removing the wall coverings carefully inspect for damage.For sealing of deep pits and fissures using mortar, smaller defects can be leveled filler.Be sure to check the surface level, to ensure there are no irregularities.

antifungal primer

antifungal primer

treated areas after drying overwritten with sandpaper, and then the whole wall covered with primer with anti-fungal properties.If the material is too porous walls, a primer is recommended to apply two coats.

Priming the walls

Step 3. Installation of insulation panels under the windows and

first insulated problem areas - the windows, radiators, door soffits.

wall insulation

Wall insulation

first accurately measure the insulated area, and then transferred to the foam measurements.Cut the sheet layout and applied to the wall.When all the pieces fit, you can start the installation.The adhesive according to the instructions diluted with water, stir well, allow to be fed.In foam adhesive composition is applied under the scheme:

Driving gluing

scheme gluing

layer of glue should be uniform and thin.After this fragment of insulation applied to the corresponding part of the wall, dub and tightly pressed against his hands.Next, attach the next fragment, until the entire site is closed foam.

Gluing

Step 4. Wall insulation

Exposed walls insulate a lot easier.Start from the bottom: foam sheet is coated with glue, put to the wall and put on a level, then firmly pressed over the entire area.

Adjacent sheets are stacked so that the seams were not gaps.Vertical joints are necessarily shifted by half a sheet, ie, in a checkerboard pattern.The entire process is constantly controlled level, or can form distortions or irregularities in the horizontal plane.When the entire area is covered with foam, you need to make a break for 2-3 days, so that the glue is completely dry.

Step 5. caulking and fixing dowels

If in the process of fixing the sheets were slit at the joints need sealing foam for the closing.Do not use foam with toluene - it destroys the structure of the insulation.Slit width of 4 cm and more foam pieces is first filled, and then blown foam.

After 3 hours, the excess foam from the treated joints neatly cut with a sharp knife, and do coat with glue joints.Further, each sheet-anchors strengthen fungi in 4-5 places.This combination will provide the insulation fixing the maximum fit and reliability in operation.

Step 6. Reinforcement and plaster

Plaster foam

Plaster

foam Insulation layer must be closed from external influence.The easiest way - to apply the plaster.To do this, first of reinforcing mesh are cut strips on the height of the wall with a small margin;the first strip is applied to the wall and the plaster is applied with a spatula to the top edge so that it is retained grid.

Reinforcement and plaster

Reinforcement and plaster

layer of plaster made up to 5 mm thick.The solution was applied with a spatula and downwards over the entire bandwidth.On the other side, where it will be mounted adjacent bands, it is necessary to leave the vertically protruding edge mesh width of 2 cm

Plaster foam

Plaster foam

important point:. Reinforcement first operate on the perimeter of door and window openings, with the batteries from the slopes andcorners, and then digging the wall sections.Along the edges of the strip are placed overlapping 1 cm;layer of plaster should be evenly distributed on the walls, completely covering the net.

Step 7. The final finishing

polishing

Grinding

dry surface treated with a special grater or sandpaper, periodically wetting the walls of water.Ironed in such a way the wall is covered with 1-2 layers of finish putty, then oshkurivayut, primed and painted.

Finishing plaster walls

If instead of paints used artistic plaster, spackling and sanding process can be skipped.This insulation of walls inside the house is considered complete.
