Verification using this definition of thermal bridge free design would imply that all details would have to be calculated in a multi-dimensional way. Therefore, simplified criteria for “thermal bridge free design” should be devised. It was found that for ordinary building geometries, the “thermal bridge free” requirement was almost always adequately met for all linear disturbances only if | Verification using this definition of thermal bridge free design would imply that all details would have to be calculated in a multi-dimensional way.
