How to insulate a concrete wall: outside or inside?

Deciding to make insulation, we can proceed in two ways: to make wall insulation outside or inside.Experts recommend choosing the first option, because it is more reliable.Like, do better insulation from the inside, but it is not so easy as it seems at first glance, so to this method should only be resorted to when it is impossible to perform work outside.

Note!Internal insulation is often the breeding ground for mold and mildew.

insulate the concrete wall from the inside, you protect it from the heat source material, and it will lead to its cooling.When severe frosts, it can be cooled so that its dew point is on the boundary with a layer of insulation.This, in turn, will cause the formation of condensation and dampness.At the same time, the greater the vapor barrier, the greater the accumulation of moisture will occur.These problems of deprived way of the outer insulation, so it is recommended as the main specialists.

outer wall treatment

Warming concrete walls outside of any materials should be carried out at a temperature not below 5 degrees Celsius.If there is a need to work at a cold temperature, the adhesives have to add special additives antimoroznye.The work on the outer insulation is held in the following order:

• prepare the ground.If there are places on the wall with an old plaster, they must be clean.The maximum level difference on the surface should be no more than 15 millimeters.If it drops more depth, they have to dub putty.Thereafter, it should be primed to improve the adhesion of the concrete;
• mount a ground profile.Width is selected in accordance with the width of the insulation;
• Apply the adhesive material on the plate.Clay is not placed evenly across the area of ​​the plate and in the corners and in the center.This attachment is strong enough, and saves adhesive solution;
• Fixing dowels.Experts recommend doing calculation of the number of dowels, based on the fact that per square meter should fall four fasteners.dowel length should be 50 mm longer than the thickness of the insulation;
• Mounting reinforcement layer.This layer is needed to enhance the strength of the assembly.To apply reinforcement mesh with 4x4 or 5x5 mm cell.Glued it from top to bottom with an overlap of 10 centimeters.After that, the whole grid is covered with plaster;

Important!Grid reinforcement must be covered with a solution that will protect it from the influence of alkalis.

• application of the decorative layer.After the insulation of the concrete wall is completed, it is necessary to treat the entire wall decorative layer to give the appearance of a house or apartment aesthetic appearance.

Internal insulation

Warming concrete walls inside differs from the outside work.The main difference is that there is a need to do a layer of waterproofing and vapor barrier, as well as lathing.The beginning of the work the same: it is necessary to prepare the wall.To do this, she removed the old paint, and cleaning is performed.Differences should be no more than 5 millimeters.All major irregularities zashpaklevyvayutsya.

Important!Note that the crate takes a certain space, so that the effective area of ​​the room is reduced.Next

of wooden bars section 10x10 cm mounted on the guide wall (crate).After that, a layer of waterproofing fit.If the waterproofing material has a foil layer, it is necessary to put the foil to itself, it will create an additional heat shield.The next step is to install the selected heater.To this end, it is firmly inserted into the space mezhreechnoe crates.When all of the material is laid on top becomes steam.

This insulation wall made of concrete completed.Now you need to cover the entire surface of the sheet material, such as plywood, drywall or plastic panels, and make the finishing decorative material.
