What Kinzler Corporation does

Kinzler Corporation is an employee-owned parent company headquartered in Ankeny, Iowa, operating a family of construction services businesses founded in 1984 by Kevin and Yvonne Kinzler. The company runs six primary business units: Kinzler Construction Services (insulation installation spanning spray foam, fiberglass, cellulose, Blown-in Blanket System, rigid board, reflective, mineral wool, and the patented "High-R" metal building ceiling insulation system invented by Kevin Kinzler in 2001 and still marketed worldwide), Kinzler Materials (construction products distribution including drywall, steel framing, acoustical ceiling tile, and EIFS), WD Door (residential and commercial garage door installation and service, acquired 2021), Leading Edge Insulation Services (Michigan operations, acquired February 2025), Banker Insulation (Arizona and New Mexico operations across nine locations, acquired May 2025), and Kinzler Retail Equipment Programs (servicing contractor-grade installation equipment for home improvement retailers across the United States and Canada, in business since 1999).

The company serves commercial builders, residential builders and homeowners, agricultural builders, and home improvement retailers across 18+ branch locations in Iowa, Colorado, Michigan, Arizona, New Mexico, and Nebraska. Operational scale is anchored by an established safety culture (Experience Modification Rate consistently below the industry average of 1.0, more than 1 million safe man-hours without lost time injury), net-zero electricity achieved at the Ankeny headquarters and Denver location via 708-panel solar installations, and recognition as a Top 25 U.S. insulation contractor by Walls & Ceilings Magazine. The company is led by second-generation CEO Tanner Kinzler and operates under an Employee Stock Ownership Plan established in 2017 that grants all employees partial ownership and a non-contributory retirement benefit.

The business model is project-quoted installation and materials distribution supported by an explicit acquisition partnership program in which acquired regional brands retain their local identity, management, and customer relationships while Kinzler supplies centralized accounting, HR, IT, marketing, and safety support through its Branch Support Office. Pricing is not publicly disclosed. Revenue is not reported. The company has been actively executing a roll-up strategy since 2021 alongside selective de novo expansion, with four announced acquisitions and one new branch opening between 2021 and 2025 and a 50% headcount increase since January 2022.
