I have two walls of glazing that meet in the corner. What are some possible mounting solutions for a corner like this?

There are two basic installation options:

The first installation option is to install one shade higher above the second shade, which reduces the gap in the corner. However, it requires a deep ceiling pocket to conceal the installation of the shades.

The second installation option is to have one shade bypass right into the corner and the other butt into it. This can yield sizeable gaps and the impact should be clearly understood.
