Contractors and fabricators can feel more confident using Knauf Performance+® fiberglass duct liner insulation because it’s reliable and meets rigorous criteria to support indoor air quality.

When cutting and fitting fiberglass duct liner insulation, it’s important to think about indoor air quality (IAQ). Many types of insulation still use red-list chemicals in their manufacturing process. These chemicals can be released into the air, causing indoor air pollution.
Knauf Performance+® duct liner supports healthier indoor air because it’s formaldehyde-free, and has earned the Asthma & Allergy Friendly® and Verified Healthier AirTM certifications.
Not only better for indoor air, its high-integrity design makes it easier to cut and position, allowing for a faster, smoother install.
