What's the difference between open- and closed-cell foam?
Open-cell is softer, lower R per inch (about 3.7), vapor permeable, and better at sound dampening. Closed-cell is denser, higher R per inch (about 6.5), structural, and a vapor retarder. Closed-cell costs more but does more in less space, the pro uses it on rim joists, crawlspaces, and unvented roof decks.

Once cured, yes. During application the chemicals off-gas and the area must be vacated and ventilated for the cure window, usually 24 hours for residential. The pro follows SPFA guidelines and the manufacturer's re-entry time. The pro doesn't take shortcuts on this.
