Destination Marvin: My Visit to Warroad

Part One: Products

By: Adrienne Stronge

As architects, we are trusted to ensure the products that we recommend to our clients are of the best quality and efficiency that is offered at their price point. We spend a lot of time during the year learning about manufacturing details and testing procedures for many of the products that go into construction. It’s why, when offered the opportunity to travel to Warroad, MN to tour the Marvin Windows facilities, I jumped at the chance to get this in-depth look at their products and the factories where they are produced.

Marvin Windows and Doors was founded in Warroad, and their window factory occupies a sprawling industrial facility of over 2 million square feet. The factory in Warroad produces the Ultimate line, which is an extruded aluminum exterior and wood interior.

We started our tour at the very beginning, where raw lumber entered the facility to be sorted and processed into the individual window parts. The wood is continuously inspected for flaws and defects that might lead to weakness in the window frame before and after each step in the process. The number of people involved in visually inspecting each component as it works its way through the facility is impressive. As the wood is further processed into the necessary part, there is always a human presence guiding the process and inspecting the piece.

In the round top and custom division, there is even more human skill and craftsmanship involved. So much of the process here is done by hand, with a select force of expert craftsmen who intricately work the wood into any design imaginable. It was especially exciting to see one of the employees there working on a window for a new UVA facility, carefully laying out the SDL bars that were dictated by a design in a historic existing building.

In addition to factory tours, we were treated to some educational sessions and given the opportunity to give feedback to the team. The feedback from our team wasn’t just noted and forgotten. Our guide pulled people in from Marvin headquarters to directly address our questions and concerns. It was amazing to get a direct response and then to receive contact information for people to follow up with in case we have additional questions.

Having worked in this industry for nearly 20 years, I thought I had a good understanding of windows, but I learned so much more than I expected and will never look at a window the same way again.
