Many building products contain formaldehyde. Residual fumes create both health and environmental problems. Today you'll learn about insulation manufacturers and the drive for greener, cleaner air. Recently the Clean Air Act was amended to require fiberglass insulation plants to clean up their act. This meant installing expensive equipment to limit the emission of hazardous pollutants, such as formaldehyde. One company took the initiative to make product changes instead, and Johns-Manville started using acrylic resin as a binder rather than you-know-what. The result? In March the EPA ruled clean-air restrictions no longer apply to J-M plants. Going still further, J-M also wraps formaldehyde-free insulation with plastic film, making it even more installer-friendly, with less itching from airborne particles. So what's in it for you? -- just greener, cleaner air. From manufacturing through installation to everyday living in your home, formaldehyde-free insulation helps you breathe easy and stay healthy.
