First Passive House Certified Window being manufactured in the USA

Passive House certified products are hard to come by in North America. We have been able to import some items but the costs are much higher when shipping and duties are added on. We are very excited to see the first Passive House certified window being manufactured in the USA. The company behind this new product is CasaGrande Woodworks http://www.casagrandewoodworks.com/index.html. They are a small scale custom manufacturer of cabinetry, millwork, custom doors, and custom windows. They are currently building around 500 window units per year and will ship to Canada. See their spec sheet here:
