The Insulation You Choose Affects The Indoor Air Quality Of Your Home

Indoor air can be 2 to 5 times more polluted than outdoor air, according to the EPA. Since your family spends roughly 90% of their time indoors, the materials inside your walls and attic matter more than you might think. Some insulation products can release dust, volatile organic compounds (VOCs), and formaldehyde into your home for weeks or months after installation. Knauf insulation has been scientifically tested against rigorous standards and is designed to help reduce exposure to these pollutants.

Knauf Performance+ Insulation: Scientifically Tested for Indoor Air Quality

WHAT TO ASK YOUR CONTRACTOR

When getting quotes for an insulation upgrade, ask one simple question: “Is the insulation you use Asthma & Allergy Friendly® certified?” If the answer is no, ask why not. You have the right to know what’s going into your walls, and you have the right to ask for materials that protect your family’s wellbeing.

The Asthma & Allergy Friendly® Certification Mark is a Registered Certification Mark of the Asthma Allergy Foundation of America (AAFA) and Allergy Standards Ltd (ASL). Verified Healthier Air™ is a trademark of Airmid Healthgroup.
