The first step in our atrium garden project was to remove the concrete. Every side of the atrium has extensive glass areas, so first these had to be carefully protected. Here plywood panels are being placed over the 10 ft. living room sliding glass door.
These panels covered the four translucent glass windows along the hallway. I doubt these could be matched if they were broken.

We were adamant that all the glass surrounding the atrium be thoroughly protected.
