How does Fallbrook's climate affect this service?

We push to R-49 minimum and air-seal the chase penetrations first.. Inland spray foam shows up on bonus rooms over garages and conditioned-attic conversions in Escondido and Vista.
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.
