COMMERCIAL INSULATING GLASS COMPANY

What COMMERCIAL INSULATING GLASS COMPANY does

Commercial Insulating Glass Company, Inc. (CIG) is a U.S. private custom glass manufacturer founded in 1998 and headquartered in Sarasota, Florida, with production operations at a single plant in Cumberland City, Tennessee. The company designs, engineers, and fabricates insulating glass units (IGUs) — including heated, tempered, multi-pane, illuminated, printed, and structural glass — primarily for the commercial refrigeration display industry, with secondary applications in architectural, appliance OEM, marine, transportation, and display-case verticals. Its flagship proprietary technology is HeatClear, a patented heated insulating glass unit using a Chemical Vapor Deposition (CVD) coating that alters the molecular structure of the glass surface to provide electro-conductive warming, condensation elimination, and approximately four times the thermal/mechanical strength of annealed glass. CIG also offers Graph-X illuminated glass with embedded LED-driven RGB graphics.

CIG operates a direct B2B go-to-market: products are custom-manufactured to buyer specifications (variable glass thickness, electrical voltage, spacer type, gas fill) and priced via quote-based, primarily one-time sales contracts, with a regional field-sales representative network covering Missouri, Michigan, Wisconsin, Texas, and Florida. Revenue is generated through custom product sales across its eight product lines — Insulating Glass, HeatClear Heated Insulating Glass, Tempered Insulating Glass, Custom Glass Doors, PVC Sliding Doors, Graph-X Illuminated Glass, Printed Glass, and Engineering Glass Solutions — for OEM refrigeration case manufacturers, food retailers, architectural projects, and other industrial buyers. The company is privately held with no disclosed institutional ownership, no funding rounds, and no M&A activity in the available record.

The current operating footprint consists of the Sarasota headquarters plus the Cumberland City manufacturing plant; cumulative scale metrics cite 25 years on market, 2,954+ customers served, and 8,700+ custom projects completed. Distribution is domestic-only (United States) with no disclosed international presence, and the company relies on a website-driven quote-request funnel supported by downloadable product literature rather than digital marketing automation.
