We are proud to announce that KAPTAIN S.A. has officially received Keystone Certification, granting us approval to sell our frames, windows, and doors in the United States.

This certification confirms that our products meet the strict standards required by U.S. building codes for structural performance, energy efficiency, and insulating glass quality. Through rigorous third-party testing and factory inspections, Keystone has verified the reliability and performance of our systems.

This important milestone allows us to bring our high-quality, European-made PVC systems to the U.S. market—with the trust and assurance of one of North America’s most recognized certification bodies.

We’re excited to offer U.S. customers the same durability, design, and energy performance that have made KAPTAIN a trusted name in Europe for over 40 years.
