Why Closed-Cell Spray Foam

Built for Northern Climate Performance

We utilize closed-cell spray foam because it performs exceptionally well in the northern climates of North Dakota and Minnesota —insulating while also creating an air and vapor barrier in one product. With high R-values that outperform traditional materials, it’s a smart investment that pays off year after year across new builds, existing homes, and a wide range of applications.
