Thermal insulation foam facade house

performed by a qualified insulation facade house from foam alone is quite real.The task of any insulation to prevent heat exchange between the room and the external environment.Insulated foam space acquires qualitative properties of the thermos.In cold weather warm air for a long time does not cool, and kept cool in the summer.This significantly affects the utility bills.

heat leaks in the unheated room reach 35%.Subject to the simple technology of facade insulation foam at home, all the work can be done by hand.The process of insulation foam facade of the house is shown in the video in the final part of the article.

Types of foam for insulation home

foam, expanded polystyrene and extruded normal belong to the same group of heaters.In composition, they are identical and only differ in density, thermal conductivity and price.installation and assembly methods have no differences.

foam , polystyrene foam insulation materials ,

  1. Expanded polystyrene foam called.Available in slabs of 1x1 and 1x0,5 m and a thickness of 2 to 10 cm thick foam used for insulation 4 facade house, depending on the thickness of the walls -.. 5 cm, and it is different in density.The most popular foams with density of from 25 to 50 units.The loose structure of the foam boards with low density have a tendency to absorb moisture.To eliminate this trouble, the foam surface is further processed waterproofing mastics.
  2. extruded polystyrene or expanded polystyrene has a higher density and, therefore, at the same thickness with insulating foam has a higher quality.Some businesses polystyrene edge equip T- shaped lock.This avoids the occurrence of cold bridges in the joints.

Any of the foams does not rot, durable and practically does not absorb moisture for warming the house.Combining with other types of foam insulation is not a violation of the technology.

Calculation of materials for facade insulation foam

home Deciding to warm facade of a private house with foam, you must make a calculation.Calculation of the necessary materials for thermal insulation is very simple.

foam - to - house - warming

  1. length of the insulated wall is multiplied by the height.From the resulting square is subtracted area of ​​door and window openings.the number of sheets of foam is then calculated.They are produced 1x1 and 1x0,5 meters.
  2. Mounting plates made from the corner in a checkerboard pattern.Calculate the required number of sheets of half-meter and meter size.On each sheet of insulation is a 5 plastic dowels (builders referred to as fungi, parachutes and umbrellas).Four anchors driven into the corners and one in the center.
  3. consumption glue mixture, dry plaster and putty depends on the thickness, brand and manufacturer.Mesh material consumption based on an area of ​​1 m2 at a different layer thickness is applied to the packaging.

For reinforcing layer must purchase a fiberglass mesh.It is available in rolls of a width of 1 meter.The total area of ​​reinforcement mesh must comply with the area to warm the surface.

tools and materials for thermal insulation of the facade of the house

  • kirochka or hammer.
  • Hatchet.
  • Building level and plumb.
  • Drill a striker or hammer, drill and concrete mixer nozzle.
  • trowel and spatula (80, 250 and 1200 mm).
  • Roulette - 5 m and flat rack (1.2 m).
  • grinder or grater with clips.
  • brush, roller or spray gun for primer.
  • Mounting knife with retractable blade.

From materials purchased:

  • foam 1h1m and 1x0,5 m;
  • dry adhesive mixture to foam;
  • dry facade plaster;
  • putty mixture "start" and "finish";
  • plastic dowel with a broad hat like "fungus";
  • deeply penetrating impregnating primer;
  • plastic reinforcing mesh (80 - 140 5x5 * cell density).

  1. Dismantle sill tides, storm pipes, hoods and other attachments on the facade of the house is insulated.A hammer or kirochka obbivat old plaster from the walls.If necessary, for a better grasp on the wall materials applied oblique notching hatchet.
  2. facade wall is aligned.Swell slipping kirochka or hatchet, and hollows and holes are sealed.You can seal the cavity with cement mortar, gypsum or alabaster.

lime wash is required to be removed.It can be scraped off or washed off with water.

  1. in a bucket of water with a drill with a mixer is mixed adhesive foam.The solution is not too liquid.It should not slide with a spatula and the foam sheet.On the meter sheet of insulation is applied uniformly 16 - 18 strokes glue.Pritiskivaetsya sheet tightly to the lower corner of the front wall and leveled across the board.The first sheet is checked and the level fixed by plastic plugs.On top of it set sheet size 1x0,5 meters.The sheet is pressed tightly against the wall and clapping hands.Thus chess order foam installation will be set.
  2. installing 7 - 12 sheets fix dowels sheets.Laying open recheck insulating sheets on the wall level, drill the corners and in the center of each hole of the sheet.The tip of each of the plastic dowel is cut with a knife.This is important, otherwise it can not open and does not gain a foothold in the nest.Plug is inserted into the hole and tamp hand to seal the foam.The central opening of the cap is inserted into the plastic anchors and strut nail is hammered with a hammer.If the cap deepened 3 - 4 mm in the foam, its seal the adhesive solution.

Smooth joints between the foam plates are coated with a mixture of glue.Slots and wide nestykovochnye glades filled with scraps of foam and glued.Sometimes cracks and hard to reach places with foam blown.

  1. On the foam is applied reinforcing fiberglass mesh.mesh band unwound from the top down, and cut with a knife mounting size.The upper part is temporarily fixed with plastic nails on the foam.The mixed plaster is taken on a wide spatula and gradually removing the solution a small spatula, grab the grid.After a few strokes at the top of the grid, promazhte its middle from top to bottom.Then race the plaster mixture to the sides.When plastering in this way it will not get off the grid and will not be wrinkles.Next band grid is placed with an overlap of 5 cm and plastered in the same way.
  2. If necessary, subject to further finishing work is done to a thin or thick 8 mm to 40 mm layer of plaster.For a thick layer of plaster is applied a metal grid.Dried out plaster covered with deep-penetrating primer mixture.Primer glues plaster layer, prevents the appearance of cracks and moisture penetration.


putty insulated and plastered facade of the house

After insulation foam at home and finish the facade of stucco, plaster done.Plastering work is not always necessary.When decorating the facade of a wild stone, ceramic tiles or siding does not need them.To whitewash or paint the facade of the need to produce a putty work.

  1. starting Dry plaster is mixed with water.Use a drill and a mixer.The solution should look like on the thick cream consistency.A small spatula (80 mm) distributed over the same plaster wide (1200 mm) spatula.Putty is applied to the plaster facade and smoothed evenly.The first layer is applied to a thickness of 3 - 4 mm.If necessary, align the walls and hide other flaws, filler layer may be thicker or after drying another layer.
  2. The finish coat is a fine dispersion structure.She applied the same way as the start.But at the same time much more carefully smoothed.Half wet putty wall treated with a grinding machine or manually with a special float clamps replaceable abrasive.As the abrasive is not recommended to use sandpaper.The pores become clogged quickly, and sandpaper comes into disrepair.For mashing putty used metal or plastic mesh.

surface of the front wall is impregnated with primer.To do this, use a brush, roller or spray gun.Dried out wall ready for painting.
