Environmental Protection

Johns Manville is dedicated to protecting our environment. That's why we recommend that you insist on fiber glass insulated duct products in your home. Our aim is to reduce your energy use, as well as the energy use of neighborhoods and communities across America. As you know, reduction of energy consumption reduces emissions of greenhouse gases by fossil-fuel burning power plants.

Johns Manville is proud to lead the way with a full line of Formaldehyde-free™ building insulation products for your home. In addition, we're working very hard to provide insulated duct system products that are Formaldehyde-free™. Not only do these products avoid adding formaldehyde to the air in your home, we also avoid emitting formaldehyde into the air during the manufacturing process.
