Tecton Products, an innovative manufacturer of fiberglass composite pultrusions, established operations in 1992 to supply Marvin Windows and Doors. Tecton pultrudes, machines and finishes each piece with a weatherable coating to produce assembly-ready components. The fusion of these components with wood has resulted in Marvin's successful Integrity window and door line. Properly designed and manufactured fiber reinforced composites are replacing traditional materials in traditional applications. The reason for this is simple: new-found performance levels along with cost advantages. This product has the tensile strength of steel as well as insulating properties. Tecton's unique process and manufacturing excellence transforms fiberglass materials into a superior performance pultruded product. Tecton is setting the standard for pultruded thin-walled complex profiles in high volume.

Tecton Products plant is a state-of-the art, 110,000 square foot facility located in Fargo, North Dakota.
