Can anyone share any experience with gsky or similar green wall panel systems in climates where soil freezing is a concern? We’ve experience building green walls in sub-tropic areas and on interiors, but I have a client who very much wants one on a south facing interior in Massachusetts. I feel like I’ve seen some in NYC on retail facades, but it may have just been a temporary thing. I will of course talk to the sales reps, but would love a second opinion.
