Anchoring curtain walls

A curtain wall can be anchored using very different systems. Timber structures are possible, as are metal systems, which can be installed in the form of a frame scaffold or with individual anchors. Aluminium should in no case be used, due to its very poor thermal conductivity λ of 200 W/mK. Steel is around 60 W/mK and stainless steel lies between 25 and 15 W/mK, thus being the most suitable.

The important thing is that the system is thermally decoupled from the load-bearing wall.

For this purpose, spacers made from heat-insulating and pressure-resistant material can be used, for instance. The anchoring system as a whole should conduct as little heat as possible from inside to outside.
