Curious how cracks in 1-hr rated walls are viewed by the industry. I'm not aware of language about having to repair a hairline crack in a rated wall. It would seem that an open crack with some measurable width to it (lets say 1/32" or greater) would need to get patched to maintain the wall rating. Thoughts on hairline cracks?
