ToughGard with Enhanced Surface is an HVAC rotary-based fiberglass duct liner with a moisture-resistant surface that offers acoustical and thermal performance. The new surface helps alleviate concerns about moisture that may enter a duct system. The air stream surface contains an Environmental Protection Agency-registered anti-microbial agent to reduce the potential of mold growth. The duct liner can be formed by press brake with sheet metal and recovers virtually all of its thickness if compressed. Edges cut cleanly with common hand tools or automated fabrication equipment, with a minimum of dust produced during the process.
