About Us
Miller Insulation Company is a 100% employee-owned insulation and scaffolding services provider headquartered in Bismarck, North Dakota. Founded in 1972 by Donald Miller, the company has grown from its roots in the oil fields to become a leader in commercial and industrial insulation, oilfield services, and professionally engineered scaffolding solutions. Today, Miller Insulation operates under the umbrella of Miller Enterprise, continuing its legacy of excellence and innovation in the industry.
Miller Insulation became employee-owned in 2015 through the establishment of an Employee Stock Ownership Plan (ESOP), aligning the interests of its employees with the company's success. This transition was driven by a commitment to empower employees and ensure the company's longevity.
