Marvin Leads in Passive Certified Windows


The passive building industry is rapidly moving beyond its infancy. Ten years ago, passive buildings were rare. Now, there are thousands in Europe, and passive building techniques are making their way across the Atlantic to the United States.

Marvin is answering the need for high-quality, high-style, U.S.-made passive products. We’re proud to have received certification from the Passive House Institute U.S. (PHIUS) for both our Ultimate Casement window (shown at left) and our Direct Glaze Polygons. No major U.S. manufacturer can match this record of achievement; in fact, our leadership in passive products was noted in a recent New York Times article.

Handcrafted in the USA, our passive products offer shorter lead times than European options. What’s more, our passive-certified windows are designed to look exactly like our regular products. You don’t give up any design flexibility with Marvin passive-certified windows.

Forward-thinking homeowners interested in passive building — or simply in superior energy efficiency overall — owe it to themselves to look at Marvin.
