About Schüco USA
Schüco International KG is a Bielefeld, Germany-based manufacturer of high-performance aluminum and steel window, door, and facade systems, operating in the United States through Schüco USA with offices in the greater Detroit area. Founded in 1951 by Heinrich Schüco Schade and now employee-owned, Schüco is one of Europe's largest aluminum system manufacturers and brings a European performance engineering philosophy to the North American specification market: ultra-narrow frame profiles, Passive House-certifiable thermal performance, integrated building automation compatibility, and precision extrusion tolerances.
Schüco's North American product portfolio includes aluminum tilt-and-turn windows and lift-slide door systems, thermally broken aluminum curtain wall and facade systems, and steel window and door lines for high-design residential and institutional applications. The tilt-and-turn window format — standard across European residential construction for its superior air sealing and ventilation control compared to American double-hung or casement windows — is the product most frequently introduced to North American custom residential projects through Schüco specification. Passive House-certified configurations of the AWS and ADS aluminum window and door series meet the most stringent thermal performance requirements in the industry, with complete window U-values reaching well below 0.20 BTU/(hr·ft²·°F).
Schüco is specified almost exclusively by architects working on high-design residential, commercial, and institutional projects where European performance standards, ultra-narrow sight lines, tilt-and-turn operation, or Passive House certification are part of the project brief. Distribution in the United States occurs through a licensed fabricator network: Schüco sells aluminum extrusion systems to licensed fabricators who manufacture and install the completed window and door products. Early engagement with a local licensed Schüco fabricator is essential — lead times and technical support are managed at the fabricator level, and not every market has fabricator coverage.

Common Applications
High-Design Custom Residential
Architect-designed custom homes where tilt-and-turn operation, Passive House certification, ultra-narrow profiles, or European aesthetic authenticity are explicit design requirements.
Passive House Projects
Residential and commercial projects pursuing PHI or PHIUS certification where fenestration U-factor and airtightness requirements exceed what domestic window manufacturers typically offer.
Institutional and High-Performance Commercial
Academic, cultural, and commercial projects specifying European-standard facade performance — particularly facades where energy modeling drives glass and framing specification.
What To Know
Passive House-capable thermal performance
Schüco's certified Passive House window and door configurations meet the most stringent thermal performance requirements available in the market — a requirement very few manufacturers can genuinely fulfill.
Tilt-and-turn operation
Tilt-and-turn windows offer air sealing, safety, and ventilation control advantages over conventional casement and double-hung windows — Schüco is the primary source for this format in the North American market.
European precision manufacturing
Schüco extrusion tolerances and hardware engineering reflect European fenestration manufacturing standards — tighter than typical North American commercial aluminum production.
