Alternative Ingredients Improve Spray Foam Insulation’s Eco-Friendly Appeal

Healthier Spray Foam Insulation: The Green Cocoon installer spraying foam insulation to enhance a building's energy efficiency. The Green Cocoon uses a spray foam that substitutes some carbon-producing ingredients with soy-based ones.

New mixtures for spray foam insulation successfully uses healthier ingredients in a construction staple that is already widely accepted as fairly green. Spray foam insulation has been applied in many types of building projects. Chosen primarily for its excellent insulating and sound-dampening qualities, spray foam is a big player in achieving LEED Points by reducing the demands for heating and cooling thus reducing energy consumption. The benefits of this product outweigh the negative points associated with spray foam, most notably the oil that is mixed with a foaming catalyst to produce it. Traditionally, spray foam is made with petrol-based oil, which, of course, is a large contributor of carbon. It is seemingly a necessary evil: not a 100% green option, but the best option available.

Heightening the competition in the green product arena foam producers are using “a soybean based polyol that can replace the conventional petroleum-based polyols [and] help the polyurethane industry become less dependent on imported mineral Crude oil” (http://www.biobasedtechnologies.com/). See my “simple duck” references below for definitions! The percentage of soybean-based substitution currently varies by manufacturer but could be upwards of twenty percent when combined with renewable and recycled materials.

This smart substitution method should act as a model for other companies that produce materials consumed by the construction industry. Investing in research and working towards higher standards of sustainability can only pay off in the end as more building projects demand the healthiest, most eco-friendly products from businesses that strive to uphold responsible practices.

“Simple Duck” terminology (as promised, which I needed in order to write about this):

What is a polyol?

A polyol is a sugar alcohol. Polyol molecules can be chained together using certain chemical procedures to produce polyesters. Soybean-based polyols have been used as a petrol-substitute to manufacture parts of farm vehicles like John Deere tractors. (Deere & Co.)

What does the polyurethane industry produce?

Varnish, skateboard/rollerblade wheels, furniture and car seat foam. Maybe these will be the next products to get a boost of green-esteem from the diverse soybean.
