Tecton Products: Past, Present and Future

Tecton Products, the world leader in pultruded fiberglass products, began in 1990 in Fargo, ND as a partnership with Marvin Windows and Doors.

Tecton Products and Marvin worked closely throughout the design, development and testing of a complete new product line featuring fiberglass frames. 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's pultruded fiberglass framing components. In 2006, Tecton Products expanded to the Roanoke, VA area with a new 75,000-square-foot plant. Our Fargo plant houses 110,000 square feet of design, engineering and manufacturing space.
