Best Insulation Types for North Dakota Homes
Spray Foam
Spray foam delivers superior air sealing and insulation performance for North Dakota homes at $1.38-$3.14/sq ft per square foot installed. Both open-cell and closed-cell spray foam expand to fill every crack and gap, making it ideal for North Dakota's climate demands — whether extreme heat, cold, or humidity. The higher upfront cost pays off through 15–20% lower energy bills and a lifespan exceeding 80 years.

Made from recycled paper fiber treated for fire and pest resistance, cellulose fills gaps and settles evenly to block drafts specific to North Dakota's climate. It's a top pick for homeowners adding insulation over existing material without major demolition.
