For 38 years, NUCO Inc. has built one reputation: sealants, foams, firestop products, and adhesives engineered to perform under real construction and industrial demands, not just meet a spec sheet.
Founded as a family business in Guelph, Ontario, they insisted on formulating their own product lines in-house — NuFlex Sealants, UltraSeal Foams, and Self-Seal Firestop — giving them a level of quality control few competitors match. That obsession runs through every silicone sealant, polyurethane foam, and firestop system, pushing consistent density, high yield, and stringent smoke-and-gas-seal ratings into applications spanning residential, commercial, industrial, and OEM markets.
Even their firestop line sits at the leading edge of the category, engineered to meet the toughest life-safety codes. It's a brand built on one standard: products that seal, bond, and protect — and keep doing it.
