CertainTeed Adds Recycled Content to ToughGard R Duct Liner to Exceed Sustainable Building Standards

March, 2009 -- In its ongoing commitment to provide HVAC customers with environmentally friendly products, CertainTeed Corporation has reformulated its ToughGard™ R duct liner by adding 25 percent recycled content.

"Using building products with recycled content is important in meeting today's sustainable building standards and very important to the environment," says Mike Lembo, senior product manager for CertainTeed's Mechanical Insulation Business. "By adding recycled content, we will use less energy during the manufacturing process and decrease the amount of waste materials sent to landfills."

Composed of rotary-type glass fibers, ToughGard R duct liner is primarily used as an acoustical liner in HVAC duct systems. It also helps fight moisture and mold growth and improves the energy efficiency in heating and cooling systems. In conjunction with receiving GREENGUARD® Indoor Air Quality (IAQ) certification in 2008, ToughGard R duct liner helps building professionals earn points for the Leadership in Energy and Environmental Design (LEED®) certification.

ToughGard R duct liner has a durable airstream surface and moisture protection. The airstream surface contains an EPA-registered antimicrobial agent, and provides exceptional resistance to tearing, puncturing and surface wear during installation and cleaning.

It is designed for systems operating at velocities up to 6,000 feet per minute (fpm) and temperatures up to 250 degrees Fahrenheit. The resilient duct liner can be easily brake-formed with sheet metal without damage and recovers all of its thickness from compression.
