Hello everyone,
we are currently building a single-family house. The shell is complete, and next week the 20cm (8 inches) external insulation will be applied. On top of that, there will be approximately 2cm (1 inch) of external plaster. We have already ordered an awning and, in this phase, have installed 5 mounting brackets for it. The installer screwed the awning brackets directly onto the bare facade; then 2cm (1 inch) spacers will be added, and the awning will be mounted on top of those. The 2cm (1 inch) spacers also serve as thermal insulation between the awning and the bracket. I am wondering whether it would be better to place these spacers between the bracket and the wall instead, or if it is thermally negligible to position the spacer between the awning and the bracket?
Best regards

What are mounting brackets? An awning consists of the cassette and wall brackets. However, these can only be installed once the wall is finished. Therefore, they may not be installed yet. What do you think?

Hello,
the mounting bracket bridges the gap between the wall made of sand-lime bricks and the 20cm (8 inches) external thermal insulation composite system. I tried to illustrate this in the picture
Sketch wall structure: 20 cm insulation outside, sand-lime brick wall inside, awning with 2 cm spacer.

Okay. Now I understand. That always needs to be bridged. Usually, the Fischer Thermax system is used for external thermal insulation composite systems (ETICS / EIFS).

Regarding your question: In my opinion, it doesn’t really matter. You will always have a thermal bridge there, but you won’t notice it in practice.
