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, we use it on rim joists, crawlspaces, and unvented roof decks.
Is spray foam safe?
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. We follow SPFA guidelines and the manufacturer's re-entry time. We don't take shortcuts on this.
