Internorm Europe's leading window brand

As a leading window brand in Europe, we offer our customers trend-setting solutions for windows, sun protection and entrance doors. An extensive product range guarantees solutions for a whole range of architectural styles and applications. Since its foundation, Internorm has been regarded as an innovation driver and sets industry standards with the continuous further development of windows and doors. The foundation of our success is the knowledge gleaned from 91 years of experience in window manufacturing, a high vertical range of manufacture and a Europe-wide network of competent sales partners. With continuous investments in resource-saving, energy-efficient and safe production processes as well as improved sales and logistics processes, we contribute to the preservation of valuable resources. Each of our most energy-efficient products makes a contribution, throughout the window’s service life, to the reduction of energy consumption in buildings.
