Thermal bridging occurs when a highly conductive material allows heat to flow more easily than through the surrounding insulated areas. This can significantly impact energy efficiency because thermal bridges create pathways for heat loss in buildings. They typically occur at certain structural elements, such as steel or concrete, where insulation is less effective.

As a result, areas around these thermal bridges can become much colder in winter, leading to increased heat loss through walls, roofs, and floors. This inefficiency necessitates greater energy consumption for heating or cooling, as HVAC systems have to work harder to maintain desired indoor temperatures. Essentially, thermal bridging undermines the effectiveness of insulation, leading to potential higher energy costs and decreased overall comfort within the space. Therefore, identifying and mitigating thermal bridges is critical in achieving better energy performance in buildings.
