How to insulate the facade of the house with a foam with their own hands

Polyfoam (expanded polystyrene) - the most common

insulation, which is used everywhere in both the insulation of the walls and for

insulation pipelines. Most often foam is used to perform

Work on the insulation of the facade of the house. There are several reasons for this, this is low cost,

Excellent thermal insulation characteristics and simple installation.

How to insulate the facade of the house with a foam with their own hands - technology

Technology of insulation of the facade of foam (expanded polystyrene)

Advantages of foam for insulation:

zero hygroscopicity (no need to use
vapor barrier films);
durability (with good finishes);
resistance to biological activity;
Stability of geometry under the influence of external conditions.

Among the disadvantages: flammable, toxicity when burning.

In general, many have an idea of how

The wall is insulated outside the hard insulation, but on how to insulate the facade

Polyfoam correctly, you need to stop more. Knowledge of features

1 - Calculation of thermal insulation material

What you need to prepare for the insulation of the facade:

Polyfoam (2560-3200 rubles / cube) or polystyrene foam (Penoplex)
(3500-5000 rubles / cube). According to its properties, these are almost identical materials,

But the polystyrene foam is more convenient in operation at the expense of the junction of the "groove comb". For
It is much more expensive;

Decorative elements made of foam for finishing facade;

primer. It is better to buy not universal, and primer
deep penetration, for example, ceresite st-17 (555 rubles / 10 l);

Adhesive for foam (dry mix). For example, Kosbud (Poland,
390 rubles / 25 kg), Ceresit Art 34 (315 rubles / 25 kg), Ceresit Art 83 (410 rubles / 25 kg);

Note. Cook glue can be prepared for this

PVC adhesive (1 l per bucket of the mixture) is added to the classic cement solution.

This technique does not greatly reduce costs, but it increases the labor intensity.

process and its duration (sifting, maintenance of proportions, kneading and

etc.).

Master notes that more convenient tool is

Glue-foam. For example, AKFIX (Turkey, 390 rubles / ball.) Or Tytan (Poland, 410

rub / ball.). Foam is more convenient in work, due to the lack of wet works and losses

time to extract the solution, and it also has much less consumption.

Social profile. Performs the function of the reference edge of the system
insulation and ensures the evenness of laying sheets, without offset horizontally.

The profile has a different width, for convenient mounting of the insulation. For example, the price of Baukom profile (Germany) is a standard length of 2,500 mm.

Calculation of foam for insulation facade

Quality insulation of the facade of the house foam is possible

only with a competent calculation of the number and the main thickness of the material with regard to

its density and thermal conductivity of the wall (brick, foam block, gasoblock).

Calculate the number is simple - enough to calculate the area

walls and add 3% on trimming (5% with a complex wall configuration).

Note. When insulating the walls of the facade of the house should think

On the insulation of the base, basement and even the foundation right up to the level of freezing.

Only such insulation can be considered effective.

It is more difficult to choose the optimal density of foam - it

Varium ranging from 15 to 35 kg / m.Kub. Note that the lower the density,

The higher the thermal insulation properties, however, the material will be the fragile.

Masters note that for the insulation of the wall of a residential building you need to use

Polyfoam density 25 kg / m.Kub. (Mark PSB-C-25) and 40-50 mm thick.

Note. General recommendation to reduce the number of bridges

cold - put sheets in two layers. Therefore, it is advisable to purchase not one

The sheet whose thickness is 100 mm, and two are 50 mm.

What foam flame is better to choose for insulation at home?

The data for selection is provided in the table (for foam

PSB-C-25 brands)

It is worth noting, to redevelop the basement in a residential premises

It is necessary not only to insulate the foundation, but also the base, floors on the soil.

Requirements for foam:

geometry. The sheet should be perfectly smooth, permissibleDeviation in length and width - 10 mm., By plane - 2 mm.;

color. High-quality material is white. Yellowness
Indicates non-compliance with storage conditions;

List integrity. For insulation, unfolded and
Deformed sheets.

2 Stage - Preparation of the facade to insulation

The surface of the wall to which foam will be glued,

Must be clean, without protruding elements. Permissible height difference - 10-15

mm. All that is higher (protrusions, hillocks) - gets off, all that is significantly lower

(recesses, potholes, cracks), it is desirable to be sealing with a solution.

How to prepare walls for insulation foam:

Painted walls - paint is removed (only if it is withzero vapor permeability);

Chalk trail - primer used;

Splashing walls - stripping with a metal brush.

A primer is applied to the prepared wall. It will increase

The adhesion of the surface and will avoid the appearance of fungus.

3 Stage - Installation of the base profile under insulation

Purpose of the ground profile for facades insulation systems -

Simplify the installation of the first row of foam sheets, and minimize the deviation

It is a good profile protection from rodents. The profile of dowels and

Mandatory verification level.

Installation of the base profile under the insulation of the facade of foam

In order to ensure the correctness of the installation of sheets and

Vertical It is recommended to install suspensions (piping cords with nut for

Weighing). Step of their installation 600-800 mm.

4 Stage - Installation of foam on the facade (slope and wall)

How to start the insulation of the facade?

Masters pay attention to the fact that users-beginners

Incorrectly choose a place to start work on the insulation of the facade. Usually they

taken over the wall, the virtue of the simplicity of work, toli due to its scale,

Then how work should be started with the arrangement of the slope.

For insulation of slopes, you can use a thinner sheet

Polyfoam. When installing, he must play the wall on the thickness of the insulation plus

15-20 mm depending on the surface of the wall surface. Excess material later

Cropped.

To provide a beautiful and tight fit of the end

Foam plastic for the window frame is recommended to use the window profile or

Profile for plasterboard (plastic angle).

Installation of foam on the wall plane begins with the bottom

An angle and is performed with a displacement of half a sheet, i.e. Sheets are stacked by B.

chess order. Thus, cold bridges are excluded.

Before starting fastening the foam to the wall, sheets are preferably

Prepare. Namely, spend on the surface of a sheet with a gear roller or

grater. This will increase its roughness and improve adhesion with glue.

How to glue foam on the facade?

The method of applying glue depends on the smoothness of the wall:

With drops of no more than 10 mm. glue applied to the surface
Sheet using a toothed spatula;

With differentials over 10 mm. The glue is applied small
"Blots" because, the adhesive need more, and the smeared sheet will be harder. For
Stacking sheet presses against a wall with minor displacements. So glue
Fills hollow space under the sheet. The remnants of the adhesive are removed by the spatula.
The peculiarity of this method of installation is that the level must be checked
Sets each sheet.

The second row of foam sheets is placed with displacement

relative to the previous one. When laying sheets in two layers, you must wait until

The previous layer will completely get dry.

Note. The finish finish of the foam of foam makes it possible

Perform decorative design of window or doorways.

Warming of the facade of foam - finishing of window slopes

Some disagreements between masters causes

Use dowels-umbrellas, disc dowels or dowels with a wide hat

(fungi). Fastening the foam to the wall of the dowels prevents offset and

The disappearance of the sheet. Part of the specialists claims that glue is enough

a strong retainer, and therefore the use of umbrellas is an extra spending

resources and time. Their opponents argue that this stage is neglected not

worth it because The umbrella will provide more reliable fixation.

Fasteners of plate dowels are possible only after full

Frozen glue. Usually it takes 1-2 days depending on the weather.

There are two ways of fastening foam:

Fastening in the middle and in the corners . In this case, used
5 dowels umbrellas for each sheet. And their total consumption is calculated taking into account
Numbers. At the same time, parts of the sheets are also attached at least three umbrellas;

Fastening in the middle and adjacent edges or corners . This
The method saves, reducing the number of umbrellas. The method is more
Preferably, since several sheets are fixed simultaneously. But this

Foundation and to avoid the destructive action of ultraviolet.

One of the ways of fastening foam umbrellas is

Cleaning a dowel into the material and the subsequent seal of the installation site

foam plug. Due to the complexity, this method is rarely used.

Crop the protruding parts of the slopes.

5 Stage - sealing seams between foam

Do not forget that the geometry of the foam sheet

sometimes leaves much to be desired, and it inevitably leads to the appearance of slots

Between sheets. Even small gaps are substantial heat loss. therefore

After laying foam sheets, it is necessary to ensure sealing (smeared

seams).

How and how to close the seams between the foam?

The procedure for performing work differs depending on the thickness of the seam:

To fill large seams, it is advisable to use
Trimming foam plane that are placed in the gap. Note, large seams
Do not fill in solution, because His thermal conductivity is much higher than
Polyfoam. As a result, through the seam will still be quite a lot
heat;

Mounting foam applies to fill thin seams,
Which is blown in the seam, and its surplus is trimmed after frozen. Eventually
It turns out the so-called "warm seam".

How and what to close the seams between the foam

Note. The protruding parts of the foam is erased by a rigid grater.

6 Stage - reinforcement of foam mesh and finishing plaster

In principle, facing the facade of foam at this stage

Ends. But unprotected insulation, not long to perform functions

Thermal insulator effectively. The fact is that the foam is destroyed under

exposure to ultraviolet and not very resistant to mechanical damage, and

So, he needs to protect.

The protective material is plaster. So that she went well and kept on a smooth sheet surface, a reinforced grid is used. It is not necessary to save on it, because the insulation technology of the facade of foam plastic provides for the mandatory use of the reinforcing grid.

7 Stage - Painting of the facade of the house after insulation of foam

After mounting on the polymer mesh foam still applied

One layer of adhesive mixture. The optimal thickness of the glue is 3 mm., And

Purpose - Hide the irregularities and give the surface to a smooth view by preparing it

Thus, to staining.

If the second decorative layer was not very smooth, his

You can align the grater. The process is time consuming, but allows you to get beautiful

Painting the facade after insulation foam is aimed at

Giving a grayish building more aesthetic species.

For staining the facade, any paint is suitable, which

Designed to perform external work. Paint is applied with a spray gun

or a soft foam roller.

It is worth noting that painting with special facade paints

Creates a film on the surface of plaster, and ensures the achievement of "effect

Thermosa ", making the house more sealed and, accordingly, warmer.

Often users refuse to staining and instead
