Appendix A - Punctiform penetrations of thermally insulated exterior walls
For estimating how high the additional heat loss due to fastening elements that penetrate the thermally insulated outer shell is, $\chi $-values for steel and high-grade steel anchors are provided in the following section. Two insulation thicknesses and two anchoring substrates are considered. The results are summarised Fig. A1. Here one can see the significant reduction in the $\chi $-value when high-grade steel is used instead of structural steel.
