A Leading Company

A Key Player in the Made-in-Italy Window Design Sector

IWG — Italian Windows Group — was founded at the initiative of Mittle, an investment company focused on Italian enterprises, with the goal of creating a hub of companies and professionals in the window industry. The first pillar of the project is Gruppo Finestre, a company active for over 60 years in window manufacturing — synonymous with quality and reliability — producing more than 60,000 units annually. It’s an ambitious, long-term project aimed at creating a center of excellence that spans the entire supply chain: from design to production, all the way to installation. The windows are made using the finest materials for both aesthetic and performance, ranging from PVC to wood and aluminum.

IWG is the result of the combined commitment of its companies and a guarantee of absolute quality — windows that blend high-quality design, exceptional flexibility, and robust production capacity. Its strong local presence, certified installation, and after-sales support reflect the quality standards that set us apart. It’s a winning formula: directly from the manufacturer to the customer, always offering the very best in terms of quality and service.
