This company's LinaTex Textile duct liner has been improved. The company reports that by fortifying the black, high-density glass mat airstream surface of the duct liner, the product has increased durability and resistance to fiber erosion when exposed to the air in commercial duct systems. In addition, the product now includes recycled content, which makes it viable for use in building projects registered with the Leadership in Energy and Environmental Design program. LinaTex now contains up to 75 percent of pre-consumer and post-industrial content.
