The Asthma and Allergy Foundation of America (AAFA) and Allergy Standards Limited (ASL)  announced that Knauf’s HVAC fiberglass insulation product line, Knauf Performance+, has been CERTIFIED by the asthma & allergy friendly® Certification Program.

The asthma & allergy friendly® Certification Program is a collaborative initiative between  ASL and AAFA that helps consumers identify products more suitable for people with asthma and allergies. Products undergo independent testing to meet scientific standards established by the program. Only products that meet those rigorous standards earn the certification mark.

Knauf Insulation, Inc., a leading, family-owned global manufacturer of fiberglass insulation, is launching this new expanded CERTIFIED line to coincide with National Asthma and Allergy Awareness Month, observed in May. With over 100 million people in the United States affected by asthma and/or allergies, Knauf’s initiative addresses the critical need for indoor air quality improvement. This product line in particular addresses concerns about indoor air pollutants, such as volatile organic compounds (VOCs).

“This certification is a testament to how deeply we care about what goes into our products, how they are made, and most importantly how they will impact installers and occupants,” said Nathan Walker, SVP Sales, Marketing and Innovation.

To earn the certification, the Knauf Performance+ CERTIFIED asthma & allergy friendly® product line underwent comprehensive scientific testing and demonstrated:

  • Compliance with airborne dust, particle, and fiber limits following installation and room disturbance
  • Resistance to fungal growth
  • VOC emissions below strict criteria 24 hours and 14 days post-installation
  • Absence of allergenic or sensitizing chemicals, or their concentration below levels of concern for sensitive individuals

“We commend Knauf’s proactive approach to addressing indoor air quality concerns through the expansion of their CERTIFIED product line,” said Dr. John McKeon, CEO of ASL. “By meeting our rigorous standards, Knauf reaffirms its commitment to providing consumers with high-quality products that contribute to improved indoor air quality and healthier indoor spaces.”

“People spend about 90% of their time indoors,” said Kenneth Mendez, President and CEO of AAFA. “When it comes to indoor air in our homes, we don’t often think about what we can’t see, like insulation that is behind walls or around ventilation systems. Knauf’s development of this innovative insulation product that meets our program’s standards will help improve indoor air quality – even though you can’t see it, it will be making a difference.”
