The Marvin Difference

The Marvin brand has two lines of windows and doors: Marvin and Integrity.

The Marvin line is a high end, made-to-order, custom window and door line made entirely of wood or aluminum cladding. The Integrity line is a pultruded fiberglass product. These Marvin lines are celebrated for their beauty, energy efficiency and durability. Many of these windows qualify for energy tax credits. In addition, they are manufactured using sustainably harvested wood, and excess shavings and waste wood materials are used to heat the manufacturing facility in Minnesota.
