When it comes to insulation, most homeowners and contractors think of energy savings, climate control, and soundproofing. But there’s a critical factor that often goes overlooked—indoor air quality (IAQ). With more time spent inside than ever before, the air we breathe in our homes matters. That’s why Dunn Lumber offers Knauf Insulation products that not only perform thermally but also contribute to a cleaner, healthier indoor environment.
Why Indoor Air Quality Matters
The Environmental Protection Agency (EPA) reports that indoor air can be two to five times more polluted than outdoor air. This pollution stems from chemicals in building materials, everyday activities like cooking and cleaning, and even the HVAC systems circulating dust and allergens.
Poor IAQ can trigger asthma, allergies, respiratory illnesses, fatigue, and long-term health concerns. As homes become tighter and more energy efficient, less fresh air circulates—making material choices all the more important. That’s where Knauf Insulation comes in.
Knauf Insulation: Engineered for Comfort and Clean Air
Knauf Insulation’s Performance+™ line is specifically designed to enhance indoor air quality while delivering industry-leading thermal performance. Its commitment to clean air is built into every product feature:
- Formaldehyde-Free with ECOSE® Technology
Knauf’s insulation is made without added formaldehyde, a common irritant found in some older insulation products. Their proprietary ECOSE® Technology uses bio-based binders with no phenol, acrylics, or artificial dyes—resulting in healthier air and safer handling. - Low VOC Emissions
Volatile organic compounds (VOCs) can evaporate into the air and affect indoor air quality. Knauf’s products are GREENGUARD Gold Certified, meaning they meet strict standards for low chemical emissions. This is especially beneficial in bedrooms, nurseries, or any area with sensitive occupants. - Mold-Resistant by Design
Moisture is a key factor in mold growth, which can seriously degrade air quality. Knauf’s insulation resists moisture and helps maintain a dry, stable environment inside wall cavities. - Asthma & Allergy Friendly® Certification
For homeowners with respiratory concerns, Knauf’s Performance+™ insulation is a game-changer. It has been independently tested and certified by the Asthma and Allergy Foundation of America, making it a trusted choice for healthy homes and schools alike.
Smart for Contractors, Smart for Clients
Using Knauf Insulation allows contractors to offer more than just thermal value—it lets them deliver peace of mind. IAQ-conscious homeowners are increasingly aware of the materials going into their homes, and Knauf’s certifications provide an edge in a competitive marketplace.
Contractors also appreciate Knauf’s consistent product quality, ease of installation, and industry support. The formaldehyde-free formula reduces jobsite odors and improves working conditions during installation, making it a preferred brand for pros across the Midwest.
