CertainTeed has added ToughGard R rotary duct liner to its HVAC market product lineup.

By combining the ToughGard liner’s properties with a green HVAC matt, it offers a way to ensure comfort and good air quality for HVAC construction projects, officials say.

"Improving the way we manufacture our rotary duct liner product dovetails perfectly with our focus on indoor air quality and product life cycle sustainability, while ensuring superior performance; ToughGard R is what our customers have come to expect," said Jim Voitel, HVAC market product manager for CertainTeed’s insulation division. "The new ToughGard R product achieves both of these goals while strengthening CertainTeed’s position as a trusted source for comprehensive insulation solutions."
