Eristehäviö

Eristehäviö refers to the loss of thermal insulation effectiveness in a material or structure. This phenomenon occurs when the insulating properties of a material degrade over time or due to external factors, leading to increased heat transfer. Common causes of eristehäviö include moisture ingress, which can fill the air pockets within insulation and increase its conductivity, physical compression of the insulation, which reduces its loft and trapped air volume, and degradation of the insulating material itself due to aging or chemical reactions.

The consequences of eristehäviö are significant, particularly in buildings. It results in higher energy consumption for heating and cooling as more thermal energy escapes or enters the conditioned space. This can lead to increased utility bills and a reduced level of comfort for occupants. In some cases, persistent eristehäviö can also contribute to condensation issues, potentially leading to mold growth and structural damage.

Identifying eristehäviö often involves thermal imaging, which can detect cold spots or areas of higher heat loss. Solutions typically involve repairing the source of the problem, such as fixing leaks to prevent moisture, and potentially replacing or supplementing the degraded insulation. Regular maintenance and proper installation of insulation are crucial for preventing eristehäviö and maintaining the long-term performance of thermal barriers.
