lämpövuotopaikoista

Lämpövuotopaikat, known in English as thermal bridges, are areas in a building's construction where heat transfers more easily than through surrounding materials. These points typically occur at junctions between different building elements or where structural components penetrate insulation layers. Common examples include wall-to-floor junctions, wall-to-roof junctions, window and door frames, and structural beams that extend through insulated walls.

The presence of thermal bridges leads to increased heat loss during colder months and unwanted heat gain during warmer periods. This can result in lower indoor temperatures in specific areas, increased energy consumption for heating and cooling, and potential condensation issues. When warm, moist indoor air comes into contact with the colder surface of a thermal bridge, water vapor can condense, creating a damp environment that may foster mold growth and damage building materials.

Identifying and mitigating thermal bridges is a crucial aspect of energy-efficient building design and renovation. Proper insulation detailing, minimizing structural penetrations, and using thermal breaks in framing are common strategies to reduce their impact. Understanding the location and nature of thermal bridges allows for targeted improvements to enhance a building's thermal performance, comfort, and durability.
