Thermal bridge

A thermal bridge is created when materials that are poor insulators come in contact, allowing heat to flow through the path created.

Insulation around a bridge is of little help in preventing heat loss or gain due to thermal bridging; the bridging has to be eliminated, rebuilt with a reduced cross-section or with materials that have better insulating properties, or with an additional insulating component (a thermal break).

Classification in construction

In construction, thermal bridges are classified as:

  • Repeating thermal bridges - where bridges occur following a regular pattern, such that made by wall ties penetrating a cavity wall.
  • Non-repeating thermal bridges - such as the bridging of a cavity wall by a single lintel
  • Geometrical thermal bridges - at the junction of two planes, such as at the corner of a wall.
