Is Spray Foam Insulation Safe? The Truth About Off-Gassing and Health Risks Spray foam insulation is effective at sealing air leaks and improving energy efficiency, but safety concerns arise due to off-gassing - the release of chemicals during installation and curing. Improper installation or incomplete curing can lead to prolonged chemical emissions, impacting indoor air quality and potentially causing health issues. Key Points to Know: - Short-term risks: Vapors during installation may irritate the eyes, skin, and respiratory system. Symptoms include coughing, dizziness, and headaches. - Long-term risks: Prolonged exposure to improperly cured foam can lead to respiratory issues and chemical sensitivity. - Safety tips: Hire certified professionals, ensure proper ventilation, and follow re-occupancy guidelines (typically 24–72 hours). - Alternatives: Consider safer, low-VOC options like cellulose, hemp, or recycled denim insulation. If you choose spray foam, prioritize correct installa...
