What Extol does

Extol of Ohio, Inc., operating as Extol, is a privately held custom fabricator of thermal insulation systems founded in 1985 and headquartered in Norwalk, Ohio. The company produces precision-cut insulation components for industrial pipe, fittings, valves, and vessels using closed-cell rigid materials — including cellular glass (Owens Corning FOAMGLAS), extruded polystyrene (DuPont Styrofoam), polyisocyanurate (Kingspan, Johns Manville TRYMER), phenolic foam, perlite, and stone wool — sized for service temperatures ranging from cryogenic (-450°F/-290°F) through high-temperature (up to 1,200°F) applications. Its core technical differentiator is the ability to fabricate preformed, numbered insulation courses and segments (notably Precision Engineered Head Segments) that match exact vessel curvatures, removing field fabrication steps and supporting corrosion-under-insulation protection through companion shields, jackets, adhesives, and vapor retarders.

The company serves four principal customer segments: industrial process facilities (the primary vertical) for mechanical piping insulation; waterworks and municipal infrastructure for buried, bridge-crossing, and above-grade pipe and tank systems; process industries (food, beverage, chemical, pharmaceutical, refining, power) for refrigeration and chilled-water systems; and OEMs (notably valve manufacturers such as Danfoss, Hansen, Henry, Herl, and Parker-Hannifin) for prototype and mass-production insulation shapes. Products ship to all 50 U.S. states and international markets from the single Norwalk facility.

Go-to-market is sales-led and quote-driven. Extol operates an inside sales team plus three regional outside sales representatives covering the Southeast, Midwest, and Northeast, supported by Request for Information and Request for Quotation forms. Pricing is not publicly disclosed and is structured around project specifications. The company holds WBENC, WSOB, and FBE women-owned business certifications, qualifying it for diversity set-aside procurement. Leadership is led by President Robin DeGraff, with VPs of Manufacturing (Cathy Demuth) and Engineering (Matt McCreedy), a National Sales Manager (Michael Irrbacher), a Plant Manager (Randy Houghtlen), and a Controller (Keith Mainzer). No disclosed funding rounds, parent company, or institutional ownership are indicated.
