US Distributor of High-Performance European Windows & Doors
Passivsupply.com represents select European manufacturers of bespoke wood windows, doors, and architectural hardware. We serve architects, builders, and luxury homeowners across the United States who require custom-engineered fenestration that domestic manufacturers do not typically deliver — solid-wood construction, European hardware, triple- and quadruple-pane glazing, and configurations built to architectural specification rather than catalog dimensions.
Why work with passivsupply
European windows and doors are different from American products in nearly every way that matters: solid-wood construction, multi-point European hardware, deeper frame profiles, triple- and quadruple-pane glazing, and a tradition of building each unit to architectural specification rather than catalog dimensions.
We specialize in connecting US architects and builders with European manufacturers who deliver this level of work. Our role is straightforward: we handle the distributor side of the relationship, so the architect, builder, or homeowner receives a clean US point of contact with seamless coordination from quote through delivery.
Selected brands
Through our partnership with Chablais European Windows & Doors, we provide US clients with direct access to bespoke European wood windows and doors — sourced from established European workshops and serving projects across the United States, the Middle East, and Europe.
Chablais is a New York-based supplier of custom European wood windows and doors for architects, builders, and luxury homeowners worldwide.

Who we serve
Architects specifying custom fenestration for residential and commercial projects. Builders coordinating high-end residential construction. Homeowners undertaking historic landmark renovations, modernist new builds, or Passive House projects where standard catalog products do not meet the design intent.
If you are working on a project that requires specifications domestic manufacturers cannot easily deliver, we would be glad to discuss it.
