CertainTeed’s fiberglass liner products now extend to spiral duct. The company has launched ToughGard Ultra-Round duct liner.
The company says the liner has several advantages over conventional double-wall liner, including a tough, fire-resistant airstream surface, scored to make installation in spiral duct easier. It also has better acoustics, and installers may find pins and adhesives unnecessary in most straight-duct situations.
“Our HVAC insulation products are proven to enhance system efficiency and contribute to more healthy and acoustically sound buildings,” said Ken Forsythe, senior product manager for the company’s mechanical and industrial insulation group. “The addition of ToughGard Ultra-Round to our product portfolio brings these benefits to an even greater number of applications, and provides real cost savings over double-wall spiral construction for builders and contractors.”
Other benefits of the liner include thermal insulating and less energy consumption, as well as an anti-microbial coating to resist mold, officials said.
