Condensation in the house, useful tips


Condensation in the house: causes, natural remedies and technical measures to avoid the formation of condensation on the walls and the appearance of mold and humidity.

There condensation it is a natural phenomenon that consists in the evaporation of the water present in the air. When the temperature rises, the air absorbs the water vapor up to saturation, increasing its volume.

Then when the temperature drops, the air expels the steam which, in contact with a colder surface, condenses, transforming into drops of water.

Condensation on the glass

The reason why we find condensation especially on the windows of the windows is due to the fact that these have a lower temperature than that of the room because they come into direct contact with an external environment.

The condensation water is pure water, that is, without salts dissolved in it, for this reason, the condensation water does not leave halos or limescale on the glass. After a hot shower in the bathroom, it is common to see condensation appear on the mirror or window glass. In these circumstances it is important to promote air exchange so as to counteract humidity by favoring the entry of air not saturated with water vapor.

Condensation on the walls of the house

It is true that the condensation water is pure, but this does not mean that it does not allow the proliferation of microorganisms such as molds.

Condensation, although not harmful in itself, can promote the development and proliferation of black mold in the coldest parts of the house. When a wall is colder than the internal environment of the house, condensation can also form on that wall.

Condensation forms on the walls which are probably accompanied by thermal dispersions. To prevent condensation from forming on the walls, you should eliminate so-called thermal bridges.

When condensation forms house walls even in the absence of heat dispersion, we generally speak of walls facing north or walls placed behind large furniture therefore more exposed to humidity because they are less airy.

Condensation in the house, the causes

Let's see in detail the causes of condensation in the house and possible home and technical remedies. The causes that lead to condensation are:

  • Indoor and outdoor climatic conditions
  • Housing conditions and concern: the number of people, plants, bathrooms, wrong habits, etc.
  • Technical condition: plastering, house construction, etc.

Condensation in the house, home remedies

Here is a list of theremedies housewares be within everyone's reach to counter the appearance of condensation.

  • Do not dry the linen inside the house except with a sufficient air change with windows, aspirators, dehumidifiers, etc.
  • Close the doors while cooking or showering and keeping an aerator on.
  • Limit the number of plants in the room.

  • Avoid ironing for hours without airing.

Condensation in the house, technical remedies

To definitively solve the problem ofhumidity in the houseand prevent the appearance of condensation in the house, it will be necessary to follow some technical measures that may include the renovation of the building.

  • Maintain the right balance between temperature and relative humidity: 20 ° c inside with humidity not exceeding 45%.
  • Ventilate frequently in order to replace the steam-rich indoor air with the steam-poor outdoor one.
  • Correctly position the radiators so that the heat touches the entire glass surface.
  • Put a dehumidifier in critical periods.
  • Check the type of interior and exterior wall paint and remedy paints that do not transpire.
  • Put a thermal coat so that any condensation between the wall and the coat can be evacuated.
  • If the problem is limited to a single wall, where condensation causes mold, set up an internal insulation system with ad hoc panels.

Condensation on walls and ceiling

There may be conditions of condensation which must be resolved with targeted methods, especially when thecondensationis present onwallsor even on theceilingof the House.

If thecondensation moisture it depends on a roof leak or infiltration of various kinds, the only solution is to repair the leak and then proceed to evaporate the water contained in the wall.

If the condensation humidity depends on rising damp, the only solution is to intervene on the specific problem.

In short, the causes can vary and it is always good to identify the factors that determine the appearance of condensation in the house to then intervene with targeted solutions.

In some cases, airing the rooms only serves as a temporary remedy to avoid having the air saturated with humidity.
