Thermal bridging is one of the major factors of heat loss in a building or home and is defined as a weakness (break) in the thermal envelope of a building. It is the path of conductivity between one side of the building envelope to the other, where heat can travel or be lost through building materials.
The impact of thermal bridging on internal comfort and energy efficiency is negated through the installation of a continuous barrier of insulation. This combats the effects of thermal bridging, limiting the amount of heat escaping or entering the building envelope via thermal bridges and achieving a higher energy efficiency rating.
To demonstrate how the total thermal resistance of parts of the building impacts different types of insulation materials, Kingspan Insulation enlisted Norman Disney & Young to conduct a thermal performance comparison assessment. The assessment compared the performance of a traditional wall lining system with bulk insulation against the Kingspan Kooltherm K17 Insulated Plasterboard wall lining system.
