What is Low VOC for Spray Foam Insulation?

All spray foam insulation products require the use of chemical components. These chemicals play a key role enabling the rapid application while helping make it easy to adhere to surfaces, resist fire, absorb sound, and deliver improved insulation performance. Many of these components are volatile and evaporate during spraying or over time from the finished foam. Collectively we refer to these as volatile organic chemicals (VOCs), and a few of these can contribute to odors and potentially other health concerns.

Because society is becoming increasingly eco- and health-conscious and technology continues to evolve supporting more eco-friendly solutions, there is a demand in this space to create greener, non-toxic alternatives to traditional insulation. This is where low VOC spray foam insulation comes in.

What is Low VOC?

Volatile organic compounds (VOCs) can be natural or man-made. Examples of VOCs in everyday products include perfumes, solvents, fuels, air fresheners, body sprays, hair spray, dry cleaning, and even the alcohol in hand sanitizers. They are often chemicals with a high vapor pressure (boil easily), although some can evaporate much more slowly. Overall, VOCs are always present in the air that can be measured. Odor is one-way VOCs can be directly detected; however, the degree can vary widely based on the chemical involved. Some VOCs, like amines, have very strong odors and can be detected at very low levels (ppm), while others can have little impact at levels a thousand times higher. Besides odor, the health impacts of VOCs vary widely between different chemicals. In general, minimizing exposure to VOCs of any kind is recommended, especially for those with higher toxicity.

As technology continues to evolve and improve, some spray foam manufacturers are pivoting toward making low VOC products. This improves indoor air quality, and raises the bar for environmentally friendlier spray foam. While these manufacturers focus on environmental and health improvements in their products, they also need to ensure that their low VOC alternatives are just as effective in their insulating performance.

What is Low VOC Spray Foam?

At Natural Polymers, low VOC spray foam starts with the selection of raw materials that are already low in VOCs, either inherently with high boiling points, produced with stringent processing conditions, or having reactive functionality that binds them into the final product. In addition, during the foaming process, unwanted side reactions can occur, but with Natural Polymers’ unique manufacturing process, they are targeted by proprietary reactive agents that decrease chemical smells and lower the number of remaining VOCs.

The result is a low-emission spray foam insulation product that delivers better indoor air quality and little to no odor.

How is Low VOC Spray Foam Different?

Natural Polymers’ Ultra-Pure™ Low VOC spray foam differs from traditional spray foam because of the manufacturing process mentioned above, as well as the application by certified installers who are trained on how to further minimize VOC emissions during the spray process. The added benefit is that Natural Polymers’ low VOC spray foam offers the same excellent insulation performance and benefits as other spray foam products including outstanding R-values, superior air sealing ability, energy efficiency qualities, improvement of building structural integrity, and sound dampening properties (open cell), in addition to being low VOC.
