Where Indoor Toxins Hide
Most American homes carry hidden toxins inside walls, under floors, and in attic insulation. Spray foam off-gases isocyanates for 20+ years. Fiberglass traps moisture and grows mold within 48 hours. Vinyl flooring releases phthalates. Newly built homes can be 5–10× more polluted than outdoor air. Knowing the source is the first step to fixing it.
