Myth: Spray foam off-gasses forever
Properly installed foam fully cures within 24 hours. After cure, it's inert. Off-gassing concerns trace back to off-ratio installs from inexperienced contractors.
Myth: Spray foam causes mold
The opposite. Spray foam eliminates the air leaks and condensation surfaces that feed mold growth.
Myth: It's too expensive
Higher upfront cost, but most projects pay back in 5-8 years and the foam lasts the life of the building.
