Nashville Air: New Siding Stealing Baby Lungs?

The glint of new siding can be deceptive. While it promises curb appeal and protection from the elements, what lurks beneath the surface – or rather, within the siding itself – can silently impact your family’s health, especially in a humid climate like Nashville, Tennessee. We’re not talking about mold; we’re talking about Volatile Organic Compounds, or VOCs.

VOCs are gases emitted from solids or liquids, and many siding materials, particularly newer synthetic options, release them. These emissions can contribute to indoor air pollution, leading to a range of health problems, especially for vulnerable populations like babies and children. This isn’t just theoretical; it’s a real concern for Nashville homeowners considering renovations or new construction.

Here’s how to navigate the complex world of siding and VOCs, ensuring a healthier home for your family in the heart of Tennessee.

First, understand the risk. VOCs are linked to a variety of health issues, ranging from mild irritations to more serious conditions. Short-term exposure can cause headaches, dizziness, and eye, nose, and throat irritation. Long-term exposure has been linked to respiratory illnesses, liver damage, and even cancer. Children are particularly vulnerable because their bodies are still developing, and they breathe more air per pound of body weight than adults.

Nashville’s climate exacerbates the problem. The city’s hot, humid summers can increase VOC emissions from siding materials. Heat causes the materials to off-gas more readily, while humidity can trap these gases indoors, leading to higher concentrations.

So, what siding materials are the biggest offenders? Vinyl siding, while affordable and durable, is a common source of VOCs, especially during its initial installation and in hot weather. Engineered wood products, like OSB (oriented strand board) siding, can also release formaldehyde, a known carcinogen. Even some types of fiber cement siding may contain VOCs in their coatings or adhesives.

Now, let’s get practical. How do you choose low-VOC siding?

1. Do Your Research: Don’t rely solely on the salesperson’s claims. Look for siding products that are certified by independent organizations like GreenGuard or SCS Global Services. These certifications indicate that the product has been tested for VOC emissions and meets specific standards.

2. Ask for the MSDS: Request the Material Safety Data Sheet (MSDS) for any siding product you’re considering. The MSDS will list the chemicals used in the product and their potential health hazards. Pay close attention to the VOC content.

3. Consider Alternatives: Explore siding options known for low VOC emissions. These include:

   • Wood Siding (Cedar, Redwood): Naturally low in VOCs, especially when finished with low-VOC stains and sealants. However, wood requires more maintenance and is susceptible to rot and insects.
   • Brick Siding: A durable and virtually VOC-free option. However, brick is more expensive than other siding materials.
   • Stone Siding: Similar to brick, stone is a long-lasting and low-VOC choice. It’s also a premium option with a higher price tag.
   • Certain Fiber Cement Siding: Some manufacturers offer fiber cement siding with low-VOC coatings. Be sure to check for certifications.

4. Proper Installation is Key: Even low-VOC siding can release some gases during installation. Ensure your contractor uses proper ventilation techniques and follows the manufacturer’s instructions carefully.

5. Let it Breathe: After installation, ventilate your home thoroughly for several days to allow any residual VOCs to dissipate. Open windows and use fans to circulate air.

But what if you’ve already installed siding and are concerned about VOCs? Don’t panic. There are steps you can take to improve your indoor air quality.

1. Air Quality Testing: Consider hiring a professional to test your home’s air quality. Several companies in the Nashville area specialize in indoor air quality testing, such as Nashville Air Quality and Environmental Assessments, Inc. These tests can identify the specific VOCs present in your home and their concentrations.

2. Ventilation: Increase ventilation by opening windows regularly, especially during and after activities that release VOCs, such as cooking or cleaning. Use exhaust fans in kitchens and bathrooms.

3. Air Purifiers: Invest in a high-quality air purifier with a HEPA filter and activated carbon filter. HEPA filters remove particulate matter, while activated carbon filters absorb VOCs. Look for air purifiers specifically designed for VOC removal.

4. Indoor Plants: Certain houseplants can help remove VOCs from the air. Some effective options include snake plants, spider plants, and peace lilies.

5. Seal Cracks and Gaps: Seal any cracks or gaps in your walls, windows, and doors to prevent VOCs from entering your home from the outside.

6. Consider Professional Remediation: If air quality testing reveals high levels of VOCs, consider hiring a professional remediation company. They can identify the source of the VOCs and implement strategies to reduce emissions.

Tennessee regulations regarding VOC emissions from building materials are not as stringent as in some other states, making it even more crucial for homeowners to take proactive steps. While the Tennessee Department of Environment and Conservation (TDEC) focuses primarily on outdoor air quality, it’s essential to remember that indoor air quality is equally important for your family’s health.

One common mistake homeowners make is assuming that all “green” or “eco-friendly” siding is automatically low in VOCs. This is not always the case. Always check for independent certifications and review the MSDS.

Another pitfall is neglecting proper ventilation during and after installation. Even low-VOC siding can release some gases, so adequate ventilation is crucial.

Finally, don’t underestimate the impact of other sources of VOCs in your home. Paints, cleaning products, furniture, and even personal care products can contribute to indoor air pollution. Choose low-VOC alternatives whenever possible.

Protecting your family from the potential health risks of VOCs in siding requires diligence and informed decision-making. By understanding the risks, choosing low-VOC materials, and implementing strategies to improve indoor air quality, you can create a healthier and safer home for your loved ones in Nashville, Tennessee. Don’t just admire the new siding; breathe easy knowing you’ve made a responsible choice.
