THE IMPORTANCE OF THERMALLY INSULATING WITHOUT CREATING HUMIDITY
One of the most discussed topics is that of thermal insulation and mold problems. Many analyzes highlight the causes of humidity and mold inside homes, but they hardly complete the topic exhaustively. Thermally insulating without creating humidity is absolutely important!
The now consolidated objective to be achieved is the reduction of heat dispersion. No intervention to reduce energy consumption can achieve appreciable objectives without a drastic reduction in dispersions and this is only possible with adequate thermal insulation of the walls and roof.
The thermal insulation of buildings, both for heat and cold, is achieved with the so-called “thermal insulation”. It can be made with very different materials. The presumed formation of mold is one of the problems often indicated as a counterpart of the installation of a thermal coat for buildings is the presumed formation of mould.
The formation of mold in a home is easily explained. It mainly depends on the combination of the high level of humidity inside the rooms and the relatively low temperature of the surface of the internal walls. The first factor is generated by the activity of people, perhaps in excessive numbers compared to the space available, by the considerable use of the kitchen and bathrooms, etc. The first necessary intervention is to try to prevent the internal surface temperature from dropping excessively during the winter period. To do this it is necessary to make thermal insulation, and therefore the “coat”.
So far, so good. However, it is necessary to add that the choice of the type of material may allow the full achievement of this objective, or bring with it some unpleasant consequences. Because it must be added that the insulation material must be “breathable” if you want to thermally insulate without creating humidity. What does breathable mean? It means that it is a material that allows the passage of water vapor. If a wall is covered with a material that is not very porous and therefore not very breathable, it will produce an accumulation of condensation. In fact, we know that air transforms into drops of water. The consequence of this will be an increase in humidity and a decrease in insulating capacity. In fact, water has very bad transmittance, meaning it allows heat to pass through easily.
It is therefore advisable to use cork and wood fiber coats (breathable natural materials); or a nanoceramic microcoat, such as Manti Ceramic; or even polyurethane. Plastic-derived materials such as polystyrene in its various forms
