Complete Spray Foam Insulation Checklist

Spray foam is permanent — get it right the first time. Follow this checklist.

Before Installation

• Decide: open-cell (cheaper, soundproof) vs. closed-cell (higher R-value, vapor barrier)
• Get 3+ quotes — specify area, foam type, and target thickness/R-value
• Verify contractor is SPFA or manufacturer certified
• Ask: who does prep work (covering windows, masking, ventilation)?
• Plan to vacate the home for 24 hours during and after spraying
• Cover or remove items in spray area — foam mist travels

During Installation

• Verify ventilation setup — exhaust fans and containment are critical
• Confirm temperature and humidity are within spec (typically 60-90°F)
• Check thickness as foam is applied — should match quoted spec
• Ensure proper mixing — off-ratio foam can smell and fail to cure

After Installation

• Do NOT re-enter for at least 12-24 hours (per manufacturer instructions)
• Ventilate thoroughly for first week post-install
• Check for any missed spots — thermal camera or touch test
• Verify depth with depth gauge or ruler in multiple spots
• Consider ignition barrier if foam is exposed (per code)
• Track energy bills — expect 30-50% reduction in heating/cooling costs
