KMI

What KMI does

KMI (Karber Mechanical Insulation, Inc.) is a privately held, SBE-certified commercial mechanical insulation contractor founded in 2005 and headquartered in Phoenix, Arizona. The company installs mechanical insulation systems for commercial and industrial facilities, covering HVAC ductwork, chilled water and steam piping, generator exhaust, tanks, pumps, kitchen grease ducts, electric heat trace systems, and weatherproof exterior applications. KMI serves general contractors, project managers, and facility owners across Arizona, with stated contract values ranging from $500 to $2,000,000 per project, and operates in verticals including nuclear, semiconductor, and retail tenant improvements.

The company's core differentiator is InsulTread®, a proprietary walkable insulation system that embeds weight-supporting insulation within jacketing and secures heavy-gauge aluminum tread plate to the exterior, designed to replace stair and catwalk systems in high-traffic or high-abuse areas. KMI also operates a separate Firestopping division (kmi-fire.com), supported by a partnership with 3M Fire Protection. Supporting the service offering are three reference tools: an Insulation Calculator (3E) based on the NAIMA 3E Plus program, an ASTM C-585 sizing chart, and IECC compliance resources for the 2009 and 2018 code editions.

KMI generates revenue through project-based construction contracts, ongoing facilities maintenance inspections and remediation, and design-assistance consultations. The go-to-market is enterprise field sales — direct contracting with general contractors, project managers, and facility owners for new builds, renovations, retrofit, and maintenance. The company maintains a network of 15+ material supplier partnerships (Knauf Insulation, Johns Manville, Owens Corning, Armacell, Foamglas, ITW Insulation, Dyplast, 3M Fire Protection, Dynamic Fabrication, among others) to source insulation products. No public financials, funding events, or institutional ownership have been disclosed.
