American Products, Inc. (API) provides reliable & economical Curtain wall choices for low to high-rise applications. Our Curtain Wall Systems are designed, engineered, constructed, and tested to meet and/or exceed Florida Product Approval & AMMA ASTM Performance standards.

API’s Curtain Wall Systems can accept ¼” and 1-5/16” glazing infills and are available in screw-spline or shear block fabrication. With screw-spline joinery, the product can be pre-assembled and pre-glazed in a controlled environment, thus increasing the quality of the product and workmanship and decreasing on-site costs and installation obstacles.

Subject to glazing and anchoring details, API can ship your frames KD (Knocked-Down) for easy field assembly. To meet the demands of tight construction schedules and decreased project budgets, API has the ability to unitize your curtain wall frames.
