Thermal Breaks

A huge challenge with using rammed earth and trying to also achieve Passive House has been how to thermally break the rammed earth from the concrete string footings and bond beams. After reviewing many many options we decided to go with autocalved aerated concrete (AAC) from Hebel.  

Hebel has an good thermal conductivity (much lower than concrete) and we are therefore using Hebel to stop the heat from flowing from the inside of the Living House through the rammed earth and out from the concrete bond beams and strip footings.
