Sensitive to growing concerns about indoor air quality and 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.
Formaldehyde is used in ordinary insulation to bond (glue) together insulation fibers to produce a rigid batt that fits into a wall or attic cavity. Consumer surveys consistently show that the vast majority of consumers prefer products made without formaldehyde when given a choice. In fact, one survey showed that over 85% of consumers prefer Formaldehyde-free™ insulation.1
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
The quality of your indoor air can be affected by growth of mold or mildew in the ducts of your HVAC systems. There are hundreds of types of molds that can induce moderate to severe symptoms in allergy sufferers. Learn more
