Spray foam insulation off-gasses toxic chemicals including MDI, VOCs, and flame retardants for up to 20 years. The EPA has documented serious health risks — here's what every homeowner needs to know.
Every spray foam product contains a cocktail of chemicals that continue releasing into your home's air for years.
Respiratory sensitization, asthma, chemical burns
Headaches, dizziness, organ damage
Endocrine disruption, cancer risk
Respiratory irritation, greenhouse gases
Fishy odor, eye/skin/respiratory irritation
Severe allergic reactions, lung scarring

Yes. Spray foam insulation contains methylene diphenyl diisocyanate (MDI) and other chemicals that off-gas volatile organic compounds (VOCs) for months to years after installation. The EPA has documented respiratory issues, skin sensitization, and chemical exposure risks from improperly cured spray foam.
Spray foam insulation can off-gas for 1-20+ years depending on formulation, thickness, and curing conditions. Open-cell spray foam typically off-gasses longer than closed-cell. Temperature and humidity fluctuations can reactivate off-gassing even years after installation.
Common symptoms include persistent coughing, shortness of breath, headaches, skin rashes, eye irritation, dizziness, and nausea. Long-term exposure has been linked to asthma development, chemical sensitization, and respiratory disease. Some homeowners report symptoms worsening on hot days when off-gassing accelerates.
GaiaCrete® hemp insulation is the safest alternative — zero VOCs, naturally fire-resistant (4+ hour rating), permanently mold-proof (pH 12+), and carbon-negative. Unlike spray foam, it improves indoor air quality by absorbing CO2 and regulating humidity.
Yes, but it requires professional removal. Spray foam bonds to surfaces and must be mechanically scraped or chemically dissolved. Mr Hemp House provides complete spray foam removal and replacement with GaiaCrete® hemp insulation for a permanently healthy home.
