kylmäsillojen

Kylmäsilta, in Finnish, translates to "cold bridge" in English and refers to an area in a building's structure where heat flows more readily from the interior to the exterior. This phenomenon occurs when a material with higher thermal conductivity, such as metal or concrete, interrupts a layer of insulation. These thermal bridges create a pathway for heat loss, leading to reduced energy efficiency and potentially uncomfortable temperature variations within the building.

The presence of kylmäsilta can manifest as colder spots on interior surfaces, which can then lead to condensation. This condensation, in turn, can foster the growth of mold and mildew, compromising indoor air quality and potentially damaging building materials. Identifying and mitigating kylmäsilta is a crucial aspect of good building design and construction to ensure thermal performance and occupant comfort. Common locations for kylmäsilta include wall studs, window frames, balcony connections, and any point where different building materials meet.

Effective insulation strategies and careful detailing during construction are key to minimizing the impact of kylmäsilta. Proper installation of insulation, thermal breaks in structural elements, and high-performance window and door systems help to create a continuous thermal barrier and prevent excessive heat transfer.
