Kosteustyyppi

Kosteustyyppi refers to the classification of moisture within building structures. This classification is crucial for understanding the source, behavior, and potential impact of moisture, thereby informing effective moisture management and building diagnostics. There are generally recognized categories of moisture types based on their origin and characteristics.

One primary category is construction moisture, which is residual water present in newly built or renovated structures. This can include water used in concrete mixing, plastering, or from damp building materials. Construction moisture typically dries out over time with proper ventilation.

Another significant type is ingress moisture, which enters the building from external sources. This can be rainwater penetrating through leaks in the roof, walls, or foundation, or rising damp from the ground. Groundwater infiltration is also a common form of ingress moisture.

Condensation moisture arises from the transformation of water vapor into liquid water when warm, humid indoor air comes into contact with colder surfaces, such as windows, walls, or uninsulated structural elements. This is often a consequence of inadequate ventilation and excessive indoor humidity levels.

Finally, operational moisture is generated by normal building use. This includes moisture released from cooking, showering, breathing, and drying laundry. While typically manageable with adequate ventilation, excessive operational moisture can contribute to condensation issues and an unhealthy indoor environment.

Understanding the specific kosteustyyppi present in a building is the first step in diagnosing moisture-related problems, preventing structural damage, and ensuring a healthy indoor climate. Different moisture types require different remediation strategies.
