Wall insulation foam with your hands

Wall insulation foam will not only reduce heat loss, but also to prepare the wall for a decorative finish.Run wall insulation foam with your hands it is possible, the main thing - to observe the technology.

Thermal insulation foam made on the outside walls.It uses slab foam or polystyrene foam - it's the same polystyrene, manufactured by more modern technologies.The advantages of this method include low thermal conductivity of the insulation layer, ease of implementation, the material resistance to moisture, good sound insulation properties.

to perform the insulation layer is required:

1. foam boards (polystyrene) in an amount equal to the area of ​​the external walls of windows net.The thickness of the plates is determined by the thermal calculations, in any case, it must be such that the dew point is shifted to the outer layer of insulation.If non-standard thickness turned out, the foam is attached to the wall in two layers, the second layer of glue only after the complete drying of the adhesive on the first layer.
2. Mineral Plate.They put in fire to around all windows, doorways, as well as between floors with a large high-rise buildings.The thickness of the plates should correspond to the thickness of the foam.Plates must be chosen with a high density.Their number depends on the number of windows.
3. Reinforcing mesh for external works.
4. Primer for walls.Primer consumption depends on the wall material - porous material to be covered in two layers.
5. adhesive for external works for the mounting foam and wire mesh.It sold as a dry mixture.
6. Perforated metal angle: to perform the starting plank - equal to the width of the layer of insulation, as well as smaller widths to strengthen the corners.
7. tool: a hammer drill Ø10 mm, length of the drill is equal to the thickness of the insulation plus 7-8 cm;Building mixer;level;stationery knife.

technology wall insulation foam

Before starting work, so you need to plan your time so as not to be left on the walls of the fixed layer is not covered with plaster foam for more than 5-7 days.Sunlight breaks down very quickly expanded polystyrene - it turns yellow, begins destructuring the surface layers, the insulation loses some of its heat-insulating properties.

1. Preparing walls.The walls are brushed clean from dust and dirt, repair and align if necessary.Differences of the walls should not be more than 2 cm in length foam sheet.If the walls are covered with paint or plaster - peel any loose areas.
2. Prepare primer.If the primer is sold as a concentrate - dilute her instructions on the package.
3. Apply primer to the wall with a brush or roller.The primer is sometimes necessary to apply several layers.Check the quality of the dried primer, you can: run your hand along the wall, with the arm should not remain significant traces of sand, construction dust or residue dye formulations.
4. Set the start bar in the basement of the building using a spirit level.Start strap is necessary to maintain the insulation layer in the adhesive dries.If the height of the building is small, you can do without it, and the first sheets of foam from the bottom needs to be fixed until the adhesive dries.

1. Bracket is attached around the perimeter of the building with the help of anchors, at least three dowels per meter.
2. Dilute the adhesive according to the instructions on the packaging for this pour the dry mix into the prepared clean, cold water.container size should be sufficient for mixing.
3. Stir adhesive using construction mixer, left to mature for 5 minutes and stir again.After that, the adhesive is ready for use.
4. Apply glue on the polystyrene plate with a spatula.Evenly distribute the adhesive on the plate only in the case of smooth walls.

1. For brick or block masonry, which is characteristic of irregularities, it is applied to a strip along the perimeter of the slab and a few blotches in the center.
2. Plate tied for the starting bar and tightly pressed to the wall, making sure that there are no distortions.
3. Check the installation plate on the level in all three directions.If necessary, align tap the plate, a hand or a hammer through a wooden block.
4. Stack plates in a horizontal row.Next put a number in a staggered manner to form a dressing, as in masonry brick walls

1. In the process of laying the foam, if necessary, cut with a knife in size.Care should be taken not to leave large gaps.
2. around window and door openings necessarily placed 20-cm layer of non-combustible insulation.As it is possible to use basalt mats or mineral plates, slabs density should be such that they withstand without deformation plaster and finish coat.If a large high-rise buildings, every 2-3 floor and laid a layer of non-combustible insulation.
3. Mineral plate is secured similarly to the foam adhesive, striking him on the entire surface.After
4. stickers can cover up all the cracks with glue if necessary, between the insulation and windows, as well as joints and insulation foam.

1. glue dries in 1-2 days.After that you need to fix the heater.To do this, use a hammer and a pair of dowel-nail.In one plate should be at least 4-5 dowels.To reduce the number of holes to be drilled hole joints plates, thereby holding two or three adjacent boards.
2. drilled holes in the plates so that the wall anchors are 5-6 cm, the length of the drill is calculated respectively as the width of the insulation plus 7-8 cm.
3. For mounting use special foam plastic dowel-fungi with a wide hat.They do not form thermal bridges, and securely fix the plate do not protrude above its surface.They clog the hammer, and then finishing off a nail in them.
4. All corners reinforce the perforated area, which is attached to the adhesive for insulation.

1. Foam should not be left in the sun for more than a few days, so after mounting plates start to finishing.The gaps between the slabs of insulation necessarily zapenivayut.For fixing wire mesh, a layer of glue on the surface of the wall, the area selected so as to have time to put and to align reinforcing mesh before the adhesive has set.Reinforcing mesh must be taken in the outside area as well as a grid for domestic work under the influence of adhesive based on cement eventually breaks down.
2. Apply a reinforcing mesh against the wall, with 5 cm along the edge of the grid should be left for the formation lap.The grid is more convenient to fix the top down, slowly unwinding roll.
3. mesh tightly pressed to the wall, and speaking over its surface smooth glue wide spatula.another adhesive can be added if necessary.The grid should not protrude above the surface of the adhesive, but its contours have to be traced.The next section is treated similarly, do not forget about the necessary overlap mesh width of 5 cm.
4. After the glue has dried, after 2-3 days, the surface of the wall will be overwritten with sandpaper, if necessary, leveling, and start finishing.

Wall insulation foam when done correctly, can save up to 40% of energy for heating homes.This foam does not rot, resistant to fungus action is not deformed by the temperature change that allows the house to maintain a decent appearance for decades.
