	A thermal bridge (sometimes referred to as a cold bridge or thermal bypass) describes a situation in which there is a direct connection between the inside and outside of a building through one or more elements that are more thermally conductive than the rest of the building envelope. As a result, there can be wasteful heat transfer across those elements, and the internal surface temperature will be different from other, better insulated internal surfaces which can result in condensation.
