Spray Foam for Scripps Ranch homes, done by a vetted local insulation crew. Spray foam does two jobs at once: insulation and air-seal. Open-cell expands to fill cavities and quiets sound.

Scripps Ranch 1990s master-plan attics are reaching the point where SDG&E rate pressure plus rising summer temperatures make the R-19-to-R-49 upgrade pay back in three to five years. Class A fire-rated assemblies and ember-resistant venting are now standard after the 2003 Cedar Fire.. Central San Diego spray foam jobs lean toward conditioned attic conversions and rim-joist work in older La Mesa and Lemon Grove housing.
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.
