CertainTeed Corp. is changing the name and appearance of its popular ToughGard 2 textile duct liner.

The liner now comes in a deep black color and is known as ToughGard T.

“CertainTeed takes pride in listening to our customers, which has resulted in making noteworthy improvements to the new ToughGard T liner,” said Ken Forsythe, marketing product manager for CertainTeed’s mechanical and industrial insulation group. “We found that a black fiberglass mat is one of the product features that contractors prefer and CertainTeed is pleased to respond to their request. The new black mat improves installation aesthetics but still contains the high-quality ToughGard coating and is available in a variety of sizes and densities.”

Typically used as an acoustical liner in sheet metal ductwork, ToughGard T improves energy efficiency by reducing heat gain or loss and condensation problems, company officials say. The liner features 75 percent recycled content.
