Soybean Foam Insulation
By: Danny Lipford
Foam insulation made from soybeans is both energy efficient and eco-friendly since it doesn’t release volatile organic compounds (VOCs) while drying. After spraying it on, the insulation expands to 100 times its size to fill every crack and crevice. This creates a seamless air barrier that can save from 30% – 50% on energy bills.
You may not think that you can look in your kitchen cupboard or refrigerator to find inspiration for energy savings, but here it is right here. While it’s true that people have made some interesting things from tofu, I’m actually talking about what all these things are made from…the soybean. And, one of the most energy-efficient and eco-friendly uses for this plant is insulation. Soy-based insulation that uses water to blow it in place is even better, because it means there will be no off-gassing of chemicals. Once the soy insulation is sprayed into your walls, ceilings and floors, it will expand to 100 times its original size, filling every nook and cranny creating a seamless air barrier. You can save anywhere from 30%-50% on energy bills and it’s also a great soundproofer.
