Thermal bridging is a big concern in the building industry, it has been recognized as a significant factor in building envelope heat loss. By reducing heat flow through a building’s thermal envelope, we can reduce energy consumption as well as prevent potential condensation issues. Building codes have increased requirements of building enclosures requiring ‘continuous insulation’ without thermal bridging. Thermal break materials can be used to reduce heat loss in wall assemblies, transitions, and structural connections throughout the building envelope. They can minimize building energy loss and improve building envelope performance.
This course will provide an overview to thermal bridging, discussing the reasons why it occurs as well as how it can be prevented. This course will also compare building details with and without thermal break solutions to highlight the importance of determining accurate values of thermal transmittance.
By the end of this online learning module, you should be able to:
Define thermal bridging
Describe why thermal bridging occurs
Explain the effects of thermal bridging
Describe how to calculate effective wall assembly U values
Describe the different solutions available to prevent thermal bridging
