How to stop condensation humidity it is a concern for many people, who find themselves fighting this problem more or less constantly. If it is also your problem ... you are in the right place, because in this study we will try to identify real solutions to this discomfort!
Humidity from condensation in the house
L'moisture from condensation, or humidity due to condensation, is one of the most common types of humidity and, above all, it is one of the most annoying, so much so that every winter many people suffer the effects, with difficulty in drying walls, glass and other surfaces. Moisture is transferred to the furniture, to the structure of the house; the windows mist up, the humidity generates condensation on the walls, and all this ends up irremediably affecting the health of the occupants.
Because the house is damp
But why the house is damp? Without going into the technical complexities of the topic, which we advise you to explore with some experts, it is necessary to remember how condensation is a phenomenon that consists in the passage of water, from its vapor state, to the liquid state, which accumulates on cold surfaces.
Although it is a phenomenon that largely depends on the climate and the relative humidity of the environment, it is actually also caused by the occupants of the same house, following the introduction of water vapor through breathing, speaking, having a shower, cooking, and so on.
The vapor that we produce is transmitted to the air up to the saturation point. When the air can no longer contain water vapor, it ends up depositing on the colder surfaces of the environment, producing condensation on the walls facing outwards, which are usually the coldest.
As it is known, the walls and ceilings of your home are the coldest surfaces of the environment, and are those that suffer most from the effects of moisture condensation. On these surfaces (especially in winter) there is the so-called dew point, that is the temperature at which the water passes from the vapor state (in the air) to the liquid one.
This explains the phenomenon that in winter fills us with problems of humidity at home and ends up complicating our lives and ruining our health. The problems of condensation humidity are aggravated precisely during this cold season, above all due to poor thermal insulation of the house, the entry of cold and humid air, and the lack of ventilation in the rooms.
Symptoms of condensation moisture
Once condensation humidity becomes a sad reality, the interiors deteriorate and show some typical symptoms, more or less evident and serious, such as black mold stains on walls and ceilings, deterioration of furniture, misting on glass and windows, the smell of humidity in the environment.
In short, also by virtue of the above it is not surprising that those who live at home with humidity problems end up suffering from health problems such as allergies, respiratory problems, lung problems, rheumatism, asthma, bronchitis, headaches and more, which end up compromising the quality of one's life.
In short, you will realize that the consequences of condensation humidity problems are no longer just aesthetic.
Also be careful to think that the problem is linked to "old" houses. In some ways, in fact, the opposite is true!
Today's homes seem designed to be hermetically sealed so that the air doesn't circulate but ... excessive insulation is not exactly the best for your health, given that there is no good natural ventilation and moisture condenses on any cold surface, such as walls, ceilings, floors and windows.

Solutions against condensation humidity
Glass is a material which, due to its thickness and conductivity, has poor thermal insulation. For this reason, window panes insulate the house only from winds, since its surface temperature is practically the same as outside.
Obviously, you will soon realize that it is no coincidence that windows suffer from condensation problems, if we consider that in winter they become the coldest surface in the environment.
To mitigate the shortcomings of glass in stopping the "sweating" of windows, fortunately, new technologies have led to the frequent use of double glazing or hermetic double glazing, as an almost irreplaceable resource for thermally insulating openings.
The hermetic double glazing, in particular, is a widespread system that consists in the use of two or more parallel glasses separated by sealed air chambers, which greatly improve the thermal insulation, avoiding the classic problems of "fog" in the glass. and therefore, of course, the effects of humidity that could negatively impact the walls.
To complete its effect and reduce condensation in the windows, the market also fixtures in aluminum and PVC with breaking of the thermal bridge, which ensure that moisture does not condense even in the material of the opening itself.
Meaning of interstitial condensation
Have you ever heard of interstitial condensation?
Remember that the problems aren't usually just condensation on walls, ceilings and floors. Humidity often also affects the inside of them.
The aggravating factor of these condensation problems is that the consequences usually manifest themselves after a long time (even years), appearing as a stain of humidity, but after having seriously deteriorated the structure of the house.
What is relative humidity?
L'humidity relative is the ratio between the amount of water vapor in a mass of air and the maximum it can withstand. When the air can no longer contain humidity, it is said to be saturated. Excess environmental humidity affects all surfaces, such as the wood and beams of the structure, pipes and electrical pipes of the house, after entering through cracks, porous surfaces and other weak areas or with insufficient insulation thermal and hydraulic.
This type of condensation humidity also tends to hit terraces and slab roofs, generating the appearance of cracks in the surface (through which rainwater will then enter), and consequently, worsening the effects of humidity.
Remember that even if it may seem a contradiction, the excess of ambient humidity can also pass through the ceilings, reaching the concrete slabs (which are not waterproofed), and which end up being victims of humidity due to internal condensation or interstitial condensation.
In order to find an effective solution against condensation humidity, we naturally recommend that you speak to an expert in the sector, who will help you identify the most appropriate remedies.
