A Guide to Choosing Low-VOC Materials & Finishes for Your Home
As homeowners place greater emphasis on the practical benefits of eco-friendly architecture, the integration of low-VOC materials has become a frequent topic in residential construction. Studies suggest that consistent exposure to high concentrations of volatile organic compounds (VOCs) can be detrimental to health, causing headaches, fatigue, and chronic concerns. The Environmental Protection Agency reports that VOC concentrations can be up to 10 times higher indoors than outdoors, due to VOCs emitted by common home materials and products.
At Trade Design Build, our skilled architects and craftsmen evaluate building materials with careful attention to performance, longevity, and indoor air quality. Below, our experts outline what VOCs are, why clients raise the topic, and four categories of low-VOC building materials to consider for your custom build or renovation.
Unsure how to select low-impact, high-performing materials for your home? Our team can help.
Key Takeaways:
Many everyday building materials emit VOCs into the air. Ongoing exposure can cause a variety of detrimental health effects.
Low-VOC selection touches nearly every layer of a build, from siding and insulation to paint, flooring, and sealants.
Trade Design Build's integrated team of architects, craftsmen, and woodworkers evaluates low-VOC products holistically to support a cleaner material palette for your home.
What Are Volatile Organic Compounds in Homes?
Volatile organic compounds (VOCs) are chemicals that have high vapor pressure and low water solubility. That means they easily evaporate into the air at room temperature, emitting gases into indoor living spaces.
Building products that often contain VOCs include:
Paints, stains, and varnishes
Adhesives, caulks, and sealants
Upholstery and spray foam
Vinyl and laminate flooring and carpeting
Cabinetry and engineered wood furniture
VOC emissions can occur for months or years after installation. Because they’re present within so many standard products, addressing VOCs isn’t a matter of selecting one or two alternative finishes. It requires an intentional approach to material selection and design throughout every stage of a build.
Should I Be Concerned About VOCs?
Several factors shape your degree of VOC exposure within your indoor space: how much of a specific chemical is present in the air, how often it’s inhaled, and how long the exposure continues. This is especially relevant for residential projects, given that people spend roughly 90% of their time indoors.
Potential short-term health risks of frequently breathing in VOCs include:
Eye, nose, and throat irritation
Nausea
Vomiting
Dizziness
Headaches
Chronic exposure to high VOC levels over several years could lead to liver, kidney, or central nervous system damage. The EPA even suspects that some of these chemicals may cause cancer with prolonged exposure at high concentrations. That’s why many public health agencies recommend reducing exposure to VOC-emitting products whenever practical.
Beyond health concerns, low-VOC building materials are typically more sustainable and perform on par with or surpass their conventional counterparts. Our team of skilled architects and craftsmen often gravitate toward low-VOC materials for their balance of practical application and superior air quality. Selecting products that are fit for purpose and align with our values ensures we create intentional spaces for discerning homeowners.
4 Categories of Low-VOC Materials to Consider When Building a Home
Choosing low-emission products and materials requires architectural firms and their clients to consider more than chemical content alone. Effectiveness, cost, comfort, and durability under daily use all factor into building and planning decisions. Work with your residential architect from the outset to resolve ambiguities early on before finalizing your finishes.
Here are four product categories along with specific recommendations to guide your material selection process.
1. Low-VOC Siding & Exterior Finishes
A home's exterior is its first line of defense against the elements. One low-maintenance siding and shingle material to consider is Eastern White Cedar. This wood is naturally durable and holds up well in a variety of climates. Its natural oils help fend off insects and decay with little to no chemical treatment, and it typically remains more stable than other softwoods. It’s also readily harvested in North America, with high certification availability.
Homeowners have several finishing paths to choose from. Those seeking to minimize VOC exposure can allow the wood to weather naturally into a silver patina. Another option is to opt for water-based, low-emission coatings that adhere well to Eastern White Cedar. Linseed oil and pine tar mixtures have seen renewed interest in recent times as low-VOC materials. They’re naturally resistant to moisture, UV rays, insects, and rot without heavy solvent content.
2. Low-VOC Insulation
Insulation is among the most consequential choices for both indoor air quality and long-term energy performance. As the construction industry shifts away from spray foam products that often emit VOCs for extended periods following installation, wood fiber insulation has gained ground. This eco-friendly insulation option offers an itch-free handling experience with no VOCs, formaldehyde, or added toxins. It can be installed as rigid boards, flexible batts, or loose‑fill fibers supported by formaldehyde‑free binders.
Hemp fiber batt insulation is a similarly nontoxic, no‑VOC alternative that consists of processed plant fibers formed into dense, flexible panels. Hemp batts offer stable performance and a naturally breathable structure that supports balanced indoor conditions.
3. Low-VOC Paint & Finishes
Though standard latex paint is widely available, it typically carries a much higher VOC content than mineral-based alternatives. Finishes like clay plaster and limewash have deep roots in architectural history, tracing back to the building materials used by ancient civilizations. In recent years, they have re-emerged as low-VOC paint options ideal for homeowners seeking breathable, mineral-based wall finishes.
Limewash in particular has gained popularity across interior and exterior applications for its velvety matte appearance and capacity to age gracefully. Its breathable composition allows moisture to pass through the wall surface rather than becoming trapped, which helps prevent mold, peeling, and blistering over time.
4. Low-VOC Floor Finishes & Cabinets
As heavily trafficked surfaces within homes, floor finishes play a major role in influencing indoor air quality and durability. Rubio Monocoat is a hardwax oil finish that has become an ideal low-VOC flooring alternative to conventional polyurethane. It penetrates into the wood grain rather than resting on the surface as a film, which preserves the wood’s natural character.
Custom cabinetry is another area that can introduce VOCs through adhesives and engineered substrates as often as through visible finishes. Formaldehyde-free plywood and solid wood construction reduce reliance on the urea-formaldehyde resins found in standard particleboard and medium-density fiberboard (MDF). Natural stone surfaces, such as soapstone and granite, require few or no chemical sealants that could gradually contribute additional VOC emissions.
Because adhesives and caulks used in flooring and cabinet installation are no longer visible once construction concludes, they’re easy to overlook when selecting low-VOC products. Consider water-based construction adhesives as a direct substitute for solvent-based sealants. These nontoxic, flexible products are made mostly from water, polymers, and natural fillers. Within an integrated design-build process, water-based products can provide sufficient bonding strength for many residential applications.
