What phenomenon describes the heat flow through studs in a wall that is not restricted by insulation?

Thermal bridging refers specifically to the phenomenon where heat flows through a material that is much more conductive than the materials surrounding it, typically occurring in framed structures where elements like studs allow heat to bypass insulation. In a wall, when insulation is installed, it breaks the path of thermal conduction. However, in areas where there are studs that directly connect the interior and exterior, they can conduct heat more readily than the insulation, leading to a localized area where heat escapes or enters the home more efficiently than intended.

Understanding thermal bridging is essential for effective insulation design because it highlights areas in a structure that can significantly influence its overall energy efficiency. Effective solutions often involve improving insulation around these areas or using thermal breaks to minimize the impact of thermal bridges on a building's energy performance.
