- Also known as cold bridging, thermal bridging is a kind of short circuit for heat transfer
- Where high conductivity materials touch, heat will bypass insulation and travel the path of least resistance.
- Calculations for facades must be in line with AS/NZS 4859.2.
- The wall total R-value (Rt) will be highly dependent on the amount of thermal bridging within the facade.
- A small amount of thermal bridging (which is normally ignored) will have a large negative effect on the Rt.
- Thermal breaks will be required for facades with metal framing.
- For more information on thermal bridging calculations and implications for your project please get in contact with the BCA Energy team.
