Recent research shows that more than a third of U.S. homeowners believe the air inside their homes is cleaner than the air outside. However, the Environmental Protection Agency says a growing body of evidence suggests that the opposite may be true. Studies have shown that indoor air quality can actually be worse than the outdoor air found in the largest and most industrialized cities.
To address the growing concerns about indoor air quality, and sensitivity to environmentally-responsible building products, Johns Manville has revolutionized the building insulation industry by offering the only complete line of Formaldehyde-free™ fiber glass home insulation. These products deliver the superior thermal and acoustical performance that you expect and help promote the healthier indoor air quality you want.
Johns Manville Formaldehyde-free™ fiber glass insulation is naturally white and helps promote better indoor air quality and healthier indoor environments because it's made without formaldehyde. This is important because formaldehyde is a toxic air contaminant often found indoors at levels in excess of health-based guidelines and recommendations.2
