Anyone with a shipping container used foam inserts for corrugation?

What’s going on miners, does anyone with a shipping container have experience with foam inserts like this? Container Inserts: Side Walls - InSoFast I think if I put these foam inserts in and then wall it off it should make it super easy to put shutter fans in. Just looking for anyone with experience or a second opinion on any downsides I might be missing. Cheers
