Indoor Air Quality
Indoor Air Quality Starts Here
Indoor air quality (IAQ) plays a critical role in the health, comfort, and performance of your home. In fact, according to the U.S. Environmental Protection Agency (EPA), indoor air can be 2–5 times more polluted than outdoor air. The materials behind your walls, inside your HVAC system, and throughout your living spaces all contribute to the air you breathe every day.
The materials hidden behind your walls, inside your HVAC system, and throughout your home play a significant role in the quality of the air you breathe every day.
Understanding those materials is the first step toward creating a healthier home.
Indoor air pollution comes from more than one source. Dust, allergens, pollen, moisture buildup, and outdoor pollutants can all find their way indoors through air leaks, poor air sealing, or everyday activities. The materials used to build and finish your home can also influence indoor air quality for years after they're installed.
Many synthetic insulation products, paints, flooring materials, adhesives, and finishes release VOCs into the air through a process known as off-gassing. These emissions can affect indoor air quality long after construction is complete.
Pressed wood products, cabinetry, flooring, furniture, and some insulation materials may emit formaldehyde, one of the most common indoor air pollutants found in modern homes.
Installing fiberglass insulation, mineral wool, or cellulose insulation can release fine particles and dust into the surrounding air. These materials often require protective equipment during installation to minimize exposure.
Poorly managed humidity levels and moisture buildup inside walls and attics can create conditions that encourage mold, mildew, and mold spores, all of which can negatively affect indoor air quality.
Outdoor pollutants such as pollen, vehicle emissions, and airborne particulates can enter a home through open windows, leaky ductwork, or air leaks in the building envelope.
Most home insulation is installed inside wall cavities where it becomes part of your home's building envelope for decades.
While these materials are out of sight, they continue interacting with the air inside your home. Some insulation products rely on synthetic binders or chemical additives that may contribute to insulation VOC emissions over time. Others require extensive ventilation before occupancy because of off-gassing during installation.
Fiberglass insulation, mineral wool, and cellulose insulation can also release airborne particles during installation, requiring protective clothing and respiratory protection.
Natural wool is different.
Havelock Wool contains no synthetic binders, adhesives, or chemical flame retardants that contribute to off-gassing. Once installed, there's nothing to cure, nothing to ventilate, and nothing to continue releasing into your living space.
A well-designed building envelope that combines natural materials with proper air sealing and ventilation can improve indoor air quality while supporting consistent indoor temperatures and long-term energy efficiency.
How Wool Supports Healthier Indoor Air
The same natural properties that protect sheep outdoors help create healthier indoor environments.
Wool's natural protein structure (keratin) chemically binds with formaldehyde, permanently sequestering it rather than simply trapping it.
Wool naturally absorbs and releases moisture vapor without losing insulating performance, helping reduce the condensation that can contribute to mold-friendly conditions.
Natural wool insulation contains no synthetic binders or chemical treatments that contribute to VOC emissions during installation or over time.
EcoStatic® Wool Air Filters help capture dust, pollen, allergens, and other airborne particles while also interacting with VOCs within the air stream. Rather than simply filtering larger particles, wool helps create a cleaner indoor environment throughout your HVAC system.
