Cold, damp walls that manifest mold problems.

Condensation is a physical phenomenon that occurs when water vapor in the air is transformed into liquid water. This occurs when air, saturated with moisture, comes into contact with cold surfaces, causing the vapor to cool and then condense into water droplets.

The phenomenon is particularly evident on cold or damp, poorly insulated interior walls of buildings, especially in rooms with high vapor production, such as bedrooms, kitchens and bathrooms. For example, during sleep, a couple can emit up to 55 grams of water vapor per hour. If this vapor comes into contact with cold walls, the resulting cooling of the air causes condensation, increasing the relative humidity of the room.

In a bedroom with two people sleeping at a temperature of 20 °C (68 °F), after four hours of sleep, relative humidity can reach 90 percent, promoting condensation on interior walls, especially in those most exposed to cooling.

To prevent damage to building structures due to condensation, it is essential to take preventive measures during maintenance work. Among these, thermal insulation using Nobilium® Thermalpanel technology is an effective solution, particularly in areas most prone to cooling.

The use of Dwall anti-bacterial dehumidifying coating, allows the surface temperature of the walls to be raised and vapor diffusion to be improved, thus helping to reduce the risk of condensation and moisture due to its thermo-hygrometric properties.

Excessive moisture and mold growth are problems that should not be underestimated for property owners. In addition to posing a significant risk to the building's structure, with potential even serious damage in a relatively short period and consequent high costs of remediation, they can cause deterioration that is difficult to repair, thus contributing to property depreciation.

Moisture, infiltrating inside the walls, increases heat loss, reducing the building's energy efficiency and compromising living comfort. This phenomenon not only leads to higher energy consumption, resulting in higher expenses, but also negatively affects the quality of life of the occupants.

Numerous studies also point out that the presence of moisture and mold in home environments can have harmful effects on health. In particular, problems such as recurrent condensation on windows, damp spots on walls, or the visible presence of mold are often correlated with an increased incidence of allergies, irritation, and respiratory tract infections among building occupants.
