YKK AP America is a leading manufacturer of high-performance architectural aluminum products for the commercial construction industry. Backed by the global strength of the YKK Group, we combine world-class engineering with local manufacturing, technical support, and project collaboration to help architects and building teams deliver exceptional building envelopes.

Our comprehensive portfolio includes storefront, curtain wall, entrances, windows, sun control systems, and specialty architectural products designed to meet the evolving demands of energy efficiency, sustainability, and occupant comfort. Systems are extensively tested to industry standards and supported by dedicated engineering, specification, and field technical resources throughout North America.

YKK AP’s vertically integrated manufacturing model sets us apart. From melting and casting our own aluminum billet to final fabrication, we maintain greater control over material quality, consistency, and long-term product performance. Our proprietary BetterBillet™ technology, now utilized across our commercial product portfolio, incorporates recycled aluminum and low-carbon sourced primary aluminum, supporting reduced embodied carbon without compromising performance.

Manufactured in the United States, our commercial systems support compliance with the Build America, Buy America Act (BABA) and are produced within an ISO 14001-certified environmental management framework. Through innovation, responsible manufacturing, and close collaboration with the design community, YKK AP remains committed to our purpose: Build a Better Society.
