Using spray foam insulation to improve the efficiency of your home or workplace’s heating and cooling systems is one of the best ways to save money in the long run. Spray foam insulation is composed of polyurethane applied in a liquid state by mixing it with a special product called a foam blowing agent. When the two liquids are combined at the tip of a special applicator gun, a chemical reaction occurs that causes the material to expand and harden, thus creating a barrier that blocks out air and water flow.
The foam blowing agent is responsible for the expansion of the foam. Because of the industry’s continuing commitment to safety and the environment, as well as additional governmental regulations, the foam blowing agents have undergone dramatic changes since their use began in the 1950s. Originally made from chlorofluorocarbons (CFCs) that were discovered to deplete the Earth’s ozone layer, the foam blowing agents were changed to hydrofluorocarbons in the early 2000s. More recently with the advanced study of global warming, a new foam blowing agent has been developed and is becoming more widely used – hydrofluoroolefins. (Try saying that three times fast!)
The product made from hydrofluoroolefins (HFOs) that is commonly used in spray foam insulation is called Solstice and is made by chemical manufacturer Honeywell.
