ACI CODE-122.1-21 (SI) PDF Download

ACI CODE-122.1-21 (SI) standard establishes the minimum criteria for designing and constructing building envelopes in order to mitigate thermal bridges. This standard is applicable to both new buildings and additions to existing structures. It specifically addresses buildings that feature concrete or masonry walls, including those with masonry veneer attached to frame walls, as well as balconies or other components that extend through the building envelope.

The code provides guidelines for mitigating thermal bridges caused by both material choices and design. It sets forth requirements for metal thermal bridges in these types of buildings, ensuring their proper management. By following the code, designers and builders can ensure that the thermal performance of the building envelope is optimized, minimizing heat loss or gain due to thermal bridging.
