The Invisible Chemicals Living in Our Homes

Most people think about their homes in terms of how they look, how they function, and how well they hold up over time. What almost never gets considered is what those materials are actually releasing into the air once everything is installed.

Every material carries a chemical story. And for many modern building products, that story doesn’t end when the project is complete.

What’s actually happening

There’s a term for this called off-gassing. It refers to the release of chemicals from materials into the surrounding air over time. Many manufactured products contain compounds used during production like solvents, binders, and stabilizers that slowly evaporate. These are often categorized as volatile organic compounds, or VOCs, which easily become airborne at room temperature.

This isn’t dramatic or obvious. It’s slow, consistent, and mostly invisible. But in a newly built or renovated home, multiple materials are doing this at the same time. Paint, cabinetry, flooring, adhesives, sealants. All contributing small amounts that, together, shape the air you’re living in.

That “new home smell”

That “new home smell” people love is actually VOCs being released into the air.

Studies on indoor air quality have shown that newly renovated spaces often have elevated VOC levels in the first weeks after installation, especially in tightly sealed homes. The smell fades as the most volatile compounds dissipate, but that doesn’t mean the process is over. Some materials continue releasing lower levels of these compounds for months or even years, particularly engineered wood products and certain synthetic finishes.

This doesn’t mean your home is unsafe. But it does mean materials are actively interacting with your environment long after they’re installed.

Where this is coming from

Where I see this come up the most is in standard construction materials. Engineered wood products like MDF and plywood often use resins that can emit formaldehyde over time. Many flooring systems, especially vinyl and laminate, rely on adhesives and stabilizers that slowly release compounds. Even paints labeled low VOC can still emit small amounts during curing.

None of these materials are unusual. They’re actually the default. The issue is when all of them are layered together in one space.

Research around indoor air quality continues to point to the same thing. The cumulative effect of multiple materials matters more than any one individual product. And since we spend the majority of our time indoors, even low level, consistent exposure becomes more relevant over time.

How we think about it

This is why I care about it, and why it’s part of how we design.

At Common Formme, we’re always thinking about materials beyond just how they look or perform. We’re asking what they’re made of, how they behave over time, and how they contribute to the overall environment of the home. We tend to lean toward materials with fewer synthetic binders and more natural integrity whenever possible. Not perfectly, but intentionally.

Some of the materials and furniture lines we carry on the floor include paints like Ecos and Portola, custom cabinetry with low VOC stains, and more considered flooring options like CALI Floors. On the furnishings side, it matters just as much. Upholstery, rugs, and finishes all contribute to the environment of a space. We tend to lean toward brands like Verellen and Cisco Home for furniture, and Armadillo for rugs, which prioritize more thoughtful materials and construction.

All of these can be seen and experienced in person at our showroom, which makes a big difference when you’re making these decisions.

What actually makes a difference

None of this requires a perfect approach. Most homes will always be a mix of materials. But small decisions across multiple surfaces add up.

Better paint selections.

More thoughtful cabinetry choices.

Paying attention to flooring systems.

Proper ventilation during and after construction.

Those shifts matter more than people think.

The end result

Over time, homes built with this level of awareness just feel different.

The air feels calmer.

The space feels more settled.

People don’t always know why, but they feel better living there.

And that, to me, is the point.
