Kosteussiltoja, or moisture bridges, refer to structural elements in buildings that facilitate the transfer of moisture from the interior to the exterior or vice versa. These bridges often occur in building materials with high thermal conductivity, such as metal or concrete, which can draw moisture from warmer, humid indoor air and release it when it reaches cooler exterior surfaces. This process can lead to condensation, mold growth, and deterioration of building materials over time.

Moisture bridges typically form in areas where different materials meet or where there are discontinuities in insulation layers. Common locations include window frames, balconies, and corners of buildings. The problem is exacerbated in climates with significant temperature and humidity fluctuations, as well as in poorly insulated structures. Over time, repeated cycles of moisture absorption and release can weaken structural components and compromise indoor air quality.

Preventing moisture bridges involves careful design and construction practices. Effective solutions include:

- Ensuring continuous insulation layers without gaps or breaks.

- Using materials with low thermal conductivity where possible.

- Incorporating vapor barriers or moisture-resistant coatings.

- Properly sealing joints and connections between different building elements.

- Maintaining adequate ventilation to reduce indoor humidity levels.

Regular inspections and maintenance can help identify and address moisture-related issues early, minimizing long-term damage. Awareness of moisture bridges is particularly important in cold climates, where temperature differences between indoors and outdoors are more pronounced. Proper construction techniques and material selection play a key role in mitigating the risks associated with moisture bridges.
