Winterizing facade foam with your hands

In recent years, all more private and high-rise buildings insulated with foam plastic, as this material is easy to install, is quite effective in its intended purpose and is available at a price.

foam insulation of facades with their hands

foam insulation of facades with their hands really done without much difficulty, if the house has one or two floors.Carrying out the same activities for the installation of insulation in the walls of the building will require a higher involvement of assistants and specialized equipment.

If you need to warm facade of the ordinary private house, then before get to work, you need to study the process technology.Breaking the rules of installation, you can not get the desired effect of the insulation, and wasted power, money and time on the work done in vain.If held assembly quality, exterior wall insulation can save on heating is quite a decent amount.

For mounting on the facade, you can use two types of polystyrene - extruded polystyrene and foam (foam).The first of these - polystyrene is the same, but with a much higher density.To know which one to choose for insulation of walls, it is necessary to consider the characteristics of both materials.

Polystyrene foam (foam )

Styrofoam plates are easily mounted on a wall with flat surface.This material is often insulated facades of houses located in areas with cold winters.

Foamed polystyrene ( foam) - an inexpensive and very efficient thermal insulator

Polystyrene panels are particularly effective for securing them outside the house, as they prevent the cooling of the walls and keep the heat inside.The positive qualities of insulation include the following properties:

- easy installation;

- ease material, by weight;

- low thermal conductivity;

- water resistance.

- reasonable price, not only in the insulation itself, but also on the mounting construction details and compositions;

- material is produced in slabs of convenient size and thickness that fall comfortably for installation work;

disadvantages of foam consider following his qualities:

- non-compliance with the rules of installation of the material, thermal insulation effect can be completely lost;

- foam is different environmental cleanliness, so it is most often installed outside the building, and the top covered with a layer of plaster, which will neutralize the negative impact;

- often foam damaged by rodents, which also reduces the thermal insulation of walls;

- flammability of the material;

- enough long life.

foam need to buy from a manufacturer that has a license for its production.Alas, ease of manufacture similar thermoinsulator attracted many, including - not the most conscientious entrepreneurs, and so the market is literally overflowing with low-quality goods such kind

Extruded polystyrene (Epps )

As mentioned above, extruded polystyrene - is the same foam, but with improved quality and correct deficiencies.Insulate this type of facade polystyrene, you can get a more solid and durable surface, rather than a conventional installation material.But extruded polystyrene has a slightly higher thermal conductivity, therefore , selecting it is necessary to buy boards having a thickness greater than the conventional foam.

The positive qualities of extruded polystyrene include:

- low flammability, because of its density and flame retardant additives;

- ease of installation - usually Epps panels have a system of locks "schip-groove" that greatly simplifies the work;

- relatively low thermal conductivity;

- water resistance and water resistance;

- longer service life than conventional foam.

- high strength characteristics - Epps used even for thermal insulation of foundations and plinths - those places that are most prone to mechanical stress.

disadvantage of extruded polystyrene is, perhaps, only a higher price.Furthermore, it has assembly certain features that should be considered when working.

Other materials for thermal insulation of facade

For reasons of "economic feasibility", consider a cheaper way to heat insulation of the facade - with the help of expanded polystyrene (Styrofoam).

To advance you can estimate the cost of the next, the reader is invited to label, where the estimate of costs of materials for finishing the 1 square meter area of ​​the facade, recalculated price of the same ratio - per unit area.(Prices - a very relative, they can vary significantly, or by region, or as a result of seasonal fluctuations).

So, for thermal insulation Materials needed:

Material Unit consumption per 1 m ² Price in rubles
Total for 1 m ² area insulated facade 600
Primer primary liter 0.25 15
adhesive composition kg 10 182
foam NDE-25-50 m ² 1 130
Dowel - "fungus" pieces 10 35
reinforcing mesh m ² 1.3 52
leveling layer kg 0.5 46
primer with quartz sand kg 0.33 20
Decorative plaster kg 0.5 120

Also mentioned in the materials table, you will need to purchase a considering size and other parameters of the building:

  • Corners plaster with reinforcing mesh.
  • Starting strap width in the thickness of insulation.
  • mounting foam, better - professional quality.
  • sandpaper.
  • Screws of different length.

Finishing and consumables should be taken with a small margin.Experienced builders are advised to expect a surplus of about 15% to at work had happened sudden shortage of a particular element.It's a shame to stop work for nothing!

Tools for

without tools in no way be able to carry out high-quality thermal insulation of the event.Therefore , preparing for work, should provide:

  • stairs.
  • spatula, trowel, grater .
  • Building knife.
  • capacity mixing glue.
  • drill with paddle-mixer or blender building.
  • Hammer.
  • Punch.
  • Building level and plumb line for spacing of straight lines, roulette.
  • roller with a long handle.
  • screwdriver .

cook in in se tools and necessary materials, you can proceed to installation of insulation.

How is the facade insulation foam

to hold warming process right, you need to proceed in stages.Both heater mounted on the facade on the same technology, so it description suitable both for one and for the other material.Insulation scheme "pie" is as follows:

1 - The wall of the building.

2 - The adhesive composition.

3 - foam or extruded polystyrene

4 - Dyubel- "fungus."

5 - Reinforcing corner.

6 - Plaster layer.

7 - Reinforcing mesh-serpyanka.

8 - putty layer.

9 - Decorative plaster.

In this scheme, one of the lost material, which is applied to each plaster and putty layer before applying the next - this primer.That it will contribute to long-term service of finishing materials, improve their adhesion to each other, will keep the entire system from the appearance of mold and mildew, as it has antiseptic properties.

To avoid errors, you need to review in detail all the stages of mounting a heater on the wall.

Preparing walls

To heater to work effectively, it must adhere to the maximum surface of the walls.Therefore , it is very important to conduct preparatory work with a facade.The preparation process includes such important issues as the alignment and embedding cracks and chips, as these flaws can become cold bridges that will contribute to lag plates on the surface of the walls.In addition, they can find "shelter" a variety of insects, which sooner or later will move into the house.

On the walls are cleaned necessarily unstable places , portions of detachment , looseness , etc.

necessarily removed from the wall unstable places, sites detachment, looseness, etc.

Sometimes cracks and crevices in ste not visible through the thick plaster - on it appears only a thin mesh of almost imperceptible cracks, but in this place and plaster begins to fall behind the wall.To grip the foam to the wall was a sturdy plaster layer must be removed, especially in those places where it is from her moves or if there are signs of its fragility, instability.

cleaning process is carried out as follows:

  • With walls and windows must remove all additional components and devices, such as air conditioners, lamps, lattice , tides, etc. In ste not should remain out of reach for cleaning..
  • Next, with walls removed exfoliated sections of the plaster, whitewash, paint and other coatings of all kinds.
  • If your wall has a raised pattern, protruding more than 5 mm, it is necessary to shoot down ordinary or hammer or hammer.
  • After removing the protruding reliefs in some parts of the walls, go to the elimination of small and large irregularities in the rest of the surface.
  • after the event to clean up, necessarily show up cracks, chips or dents.Above them seriously need to work, as they become less and start expand - may well.Therefore, they need to expand their own with the help of a drill or a spatula, if it is possible , then thoroughly clean from dust, sprinkle with water.Depending on the size of the resulting gaps, they are filled with sealant, concrete solutions, the adhesive masses based on cement or assembly foam.

  • After drying on repair patches cracks and chips, it is necessary to remove the sealing material is speaking out.
  • Next, is check on the evenness of the walls, as very often the walls are or small, or even enough serious distortions that would prevent the rapid installation of insulation and its tight fitting properly.If any show up, they are encouraged to align in advance to smooth installation of the foam boards is quick and easy.

evenness of the walls is checked using the plumb and construction level.After surfacing, they must be thoroughly dried.

  • Prepared wall recommended cover the primer and wait for it complete absorption and drying of the surface.

  • Further, the walls are reinforced with mesh-serpyanku.For this , since top of the wall on her wide spatula applied plaster composition, and it is applied serpyanka.From above it is pressed to the wall with a spatula, and the excess putty removed.
  • After drying putty , wall to be treated more times primer, which will create a good adhesion between the surface of the walls and glue on which will be installed insulation.
  • Before starting the installation of insulation, the wall surface must be thoroughly dried.

Setting Profile-stand

For reliable maintenance of all insulation from the bottom of the system, as well as to set the correct direction, the wall is fixed a special profile-stand (or starting strip), which will not allow to slip a heater downduring its sticking.The width of the insulation element of the system must be equal to the thickness acquired foam.

Whatever was not used insulation , reduce the need to establish a reference profile .

Whatever applied insulation, reduce the need to establish a reference profile.

Before fix profile Wall , need to carry out marking his place mounting - this proce ss etc. Gadfly using a spirit level or painted rope , which on wall bounces smooth horizontal line - on it and will start to level off the bar.

Fixing profile to the wall with dowels made hockey, size 6 - 7 mm - they usually are driven (screwed) every 350 ÷ 400 mm.

Installation support starting strips

installation support straps starting

on corners of the house starting strips are fastened with special corner joint made of plastic.These items will be expansion joints at temperature changes, quenching linear expansion of the material.

Installing insulation

When the basis for the installation of the foam is attached, the following step is conducting communications that should be hidden under a layer of insulation, and strengthening tides under the windows.

  • After these steps, you can proceed to install the insulation on the slopes of windows.
  • advance study guide for the production of adhesive mass - she should get involved strictly on specified proportions.

There is a special glue for foam installation.It should be kneaded in strict accordance with the instructions

  • Glue is applied to the foam plate and dot on all sides.The thickness of the blend layer will depend on how much surface of the wall aligned.For example, if there are irregularities in the wall 9 ÷ 15 mm, the solution is applied to a thickness of 12 ÷ 20 mm.
Apply the adhesive on the tiles - the perimeter , and point - in the middle

Apply the adhesive on the stove - on the perimeter, and point - in the middle

  • With window and door slopes are measures taken, and it cut out the insulation.Then it is applied to the adhesive mass.Billets are applied and pressed to the slopes.When this work is completed, go to the warming of the main surface of the walls.
  • Installing foam begins from the bottom wall, relying on the profile prepared for him.
