Glass Engineering Solutions: Specialized Solutions for Every Project
At Complementary Glass Industry & Innovative Solutions, we are more than a glass manufacturer; we are a provider of engineering solutions for architects, developers, designers, and a wide range of industries.
Every project presents its own unique challenges and requirements. In some cases, safety is the highest priority; in others, energy efficiency, aesthetics, or sound control take precedence. Some projects also require advanced technologies such as smart glass or security-resistant glazing systems.
For this reason, we have categorized our products not by their manufacturing process, but by the challenges they are designed to solve.
Each solution we offer is the result of combining engineering expertise, more than three decades of experience in the glass processing industry, advanced production lines, and specialized technologies. Depending on the project requirements, a solution may incorporate one or more technologies, including tempered glass, laminated glass, insulated glass, enamelled glass, printed glass, bullet-resistant glass, smart glass, and other specialized glass technologies.

About Us
Our story began in 1965 with the trusted and long-established name of Qazvin Glass. However, we did not limit ourselves to the production of raw glass. Recognizing the growing demands of modern architecture for safety and energy efficiency, we strategically shifted our focus toward the glass processing industry in the mid-1990s.
