cton Products began in 1990 as a partnership between John Jambois and Marvin Windows and Doors. Jambois business plan was to design a window and door product line using pultrusions for the framing components. Tecton Products and Marvin worked closely throughout the design, development and testing of these products. The result was the successful Integrity product line for the new construction market. In 2002, Infinity from Marvin was introduced for the replacement window market, again featuring Tecton Products pultruded framing components. The company has become one of the highest volume pultruders in the world. It manufactures products 24/7 in an 110,000-square-foot plant. The company achieved ISO 9001:2000 certification in 2002. In 2005, it earned North Dakota's first OSHA Safety and Health Achievement Recognition Program designation. Tecton Products maintains an active presence in the American Architectural Manufacturers Association, the National Fenestration Rating Council, the Association of Millwork Distributors and the National Association of Home Builders.
