Wall insulation foam with your hands

Wall insulation foam hands - a very common technology, as it is quite a simple process using readily available materials and costs. Styrofoam (polystyrene) due to its physical and operational characteristics is very popular for the processes of thermal insulation of facades and balconies.The only - interior walls it is not recommended material.

Facade insulation foam is carried out in different ways:

- binding material panels on the walls with adhesive, followed by finishing it with plaster or masonry;

Why insulationmost or foam cladding is selected based materials?This is due to its specific properties:

  • material is flat and firm.These features facilitate and speed up the installation process and makes the walls almost perfectly smooth.
  • Easy material allows the installation yourself.It easily can be raised to any height without using special equipment, and it is well kept on the wall surface.
  • Low thermal conductivity well delay the heat indoors, and high noise reduction will maintain the silence in the house.
  • waterproof material will protect the walls from the effects of rainfall and high humidity.
  • Insulation does not require its installation time-consuming preparatory work, such as the device crates (although such an option is possible and if the wall does not differ flatness).
  • And yet another advantage of this material over other heaters - is its affordable price.

Wall insulation foam hands - from start to finish

To work went quickly and without a hitch, not to dispense with preparatory activities, which include determining the amount of the desired material, its acquisition, as well as buying and preparing the necessary tools.

Next ide t t Carefully prepare the surface of the walls, and only then you can proceed to the installation polystyrene panels.

Tools and materials

  • first thing you need to do - is to spend calculation of thermal insulation material.To do this, we calculate the total area of ​​the walls of the house to be warming.Thermotechnical calculation will help you choose the thickness of the foam, which is based on the determination of the dew point offset.When calculating the thickness is too large, the foam can be laid in two layers.The second layer of material is attached only after the first has dried completely.
  • If you use normal foam PPP , in order to fire safety around the openings doors and windows is recommended to lay the mats of mineral wool.The thickness of these fire breaks should be equal to the thickness of the foam, and the width - least 200 ÷ 250 mm.The mineral wool must have a high density, to an approximate density polystyrene.

If applied extruded material, can do without the use of mineral wool because it is practically non-flammable .But this type of foam has a somewhat higher thermal conductivity.

  • need for reinforcement of insulation mesh-serpyanka.Her impose top pasted on the walls of the foam, as it is without any external cladding (eg plaster layer) after a while begin to crumble.

  • To prepare the walls need a primer.Her consumption will depend on the porosity of the wall material.In addition, it is necessary to take into account, from which the walls were built specifically as wood, brick or cement need to buy different types of primers.The walls are covered with soil in two layers.
  • foam adhesive for fixing to the walls of the bags could be sold as a dry mortar, or cylinders in the form of a substance resembling assembly foam.

Tools needed to work

tools needed to work

  • Of the tools needed spatulas, straight and gear , building knife nozzle mixer at a power drill, level, hammer drill with a drill length of 60 ÷ 80 mm more than the foam thickness,10 mm in diameter, glue container manufacture, if it is made from a dry mix.

Surface preparation

cook in in se necessary, you can proceed to the preparation of the surface of the wall.Without this phase of the work is high quality, so it can not be ignored.

  • first audited wall.The surface must be more or less flat.To do this, from the wall bulges and slipping all closed up all the deep depressions.The need for this due to the fact that the speakers flaws prevent insulation boards adhere to the surface, and the significant deepening, unfilled adhesive, can lead to a backlog of foam from the wall.
  • next step after the alignment is cleaning the walls from dirt and dust.This work makes hard and soft brushes .With colored walls it is necessary to remove all the old loose paint.
  • After preparing the walls can move on to breeding primer.If the liquid is acquired in the concentrate, it should be diluted according to package directions.
  • Primer cover the entire surface of the wall - this process can be carried out using a roller or wide brush.Basically GRU nt etc. ihoditsya applied in two or even three layers, as long as the wall is not well fortified.This can be verified as follows: after the primer is dry, you need to spend on the wall by hand.If not on the palm will building sand or dust hence primed surface is no longer necessary.
  • On primed and dry wall around the perimeter of the bottom of the building bounces color strictly horizontal bar.From this mark and will be the installation of thermal insulation panels.
  • As planned the "zero" line is fixed metal profile, which will perform a support role for the first series of insulating plates.Perforated metal profile is fixed to the wall with anchors or dowels, and wooden walls will be enough screws.

Installing insulation

When mounting is necessary to consider some features, not to spoil the material, and all the work done.Insulation, mounted on the wall should not be without coating it with plaster over 4 ÷ 7 days, as UV rays are damaging effect on EPS.He loses his insulating properties , going destructuring surface of the insulation material turns yellow and begins to crumble.That is, if the master does not have time for this deadline to sheathe the walls and plaster, it is necessary to first insulate and decorate one wall or two and then move on to the following surfaces.

Driving walls, insulated foam

process is the following:

  • If insulating works the extruded material, then over it have a little work, because he is absolutely smooth surface, and is very low in panelscoupling a wall component.To improve traction, the plate is treated with a spiked roller, which will give the material a certain relief.You can walk on a smooth surface and a metal brush - it also makes it rough.
  • spiked roller Processing increase adhesion of extruded polystyrene with a wall surface

    Processing spiked roller will improve adhesion to the surface of extruded polystyrene wall

can buy and ready for gluing extruded foam sheets, in which the relief surface is performed still in the process of production.

  • Clay must be diluted according to instructions.In a large enough capacity poured cold water in her poured dry mixture.The solution is mixed by means of a special nozzle which is installed in an electric drill.The glue should be thoroughly be stirred - have a smooth consistency and does not contain lumps.The mixture should insist for 4 - 5 minutes, and only after that you are ready to further work.
  • adhesive weight is applied to the Foam sl st eduyuschim way - sufficiently wide strip around the perimeter and three four ÷ lyapami in the center of the plate.

  • Having obtained the lower row, move to the second, which is placed on the system bricklaying - in dressing .
  • In some places, the foam sheets need to be cut to size in advance planned, such as internal and external corners, window or door openings .
  • sheet material shall be placed close to each other.It happens so that the gaps of different size formed therebetween.They are, after all the work after drying glue sealed with neatly cut pieces of foam or construction foam .

  • recommendations should not forget that the door and window openings framed 200 ÷ 250 millimeter mats of mineral wool having a high density.They also fixed to the glue.This material is on par with the foam must quietly endure sticker reinforcing mesh and application layers plaster mixture.
  • After the foam stickers to the surface of the walls, you need to wait for a period of 2 ÷ 3 days - the time necessary for the glue dries. Next process is conducted securing plates to the wall with gvozdey- "fungi".

Mount - "Fungus»

  • In each of the plates is drilled through 5 - 6 holes that need to be deepened into the base wall 6 -. 7 cm in the opening set and hammer "fungi» - dowels, and then they hammer a nail special, which will squeeze hat to the foam, and the material itself - the wall.The cap of the fungus should be recessed into the insulation, and to be on par with the total surface.

Fixation "fungus" in the hole

  • should be noted that on krepleniyah- "fungi" can be saved by scoring their plates at the joints, thus pressing immediately two or three plates.
  • After fixing all fungi, you can proceed to the reinforcement corners.They are attached by adhesive, metal or plastic with a grid serpyanku corners.
  • As mentioned above, the foam can not be left in the sun for a long time, and after drying and fixing corners, you must immediately begin to reinforcement of the entire surface of the insulation.
  • top of the foam with a spatula spread the glue, but it is applied to a small area, so it dries quickly.
  • best to start applying glue to the top of the structure, so that you can immediately fix serpyanku.It is recessed into the adhesive layer, pressed and smoothed.The mesh should be completely immersed in the glue and the excess solution is removed with a spatula.
Placing of reinforcement mesh - serpyanku

laying reinforcing mesh-serpyanku

  • taped serpyanku the first web, the second stack on his lap , approximately 50 mm.
  • cover the surface of the adhesive and serpyanku walls left for 2 ÷ 4 days to dry.
  • After the final drying of the walls, they must be carefully wipe with sandpaper, if necessary.
  • Next is leveling layer of plaster.

Thermal panels with foamed polystyrene base

More one facing material on the basis of foam are thermal panels.Applying it to insulate houses, we can solve three problems at once - is thermal insulation, sound insulation and decorative finishing of the building.The variety of the color and texture palette allows you to choose the panel to suit every taste and color.Thermal panels allow to transform the house, built of any material, even from the logs, but in this case have to make on the walls of the facade of the crate .

Thermal panels thanks to its design, easy to install.They provide excellent protection to the walls from moisture, as they are waterproof.

basis, different models may have different thermal panels heat-insulating materials, but one of the most common remains polystyrene.
