About

Our story

Art Yapı Malzemeleri San. ve Tic. A.Ş. was established in İstanbul in 1987. What started as a small local supplier has grown into a trusted national manufacturer of PVC windows, entrance doors and sliding systems, serving developers, contractors, architects and homeowners.

Our 4,000 m² factory and storage facility in Dudullu OSB, Sancaktepe, is equipped with a modern CNC processing centre (işleme merkezi). More than 30 skilled people produce over 700 windows per week, and every element passes our quality control before it leaves the factory.

Global reach, local impact

Our work is not confined to Türkiye. Art Yapı has completed projects in Germany, Malta, the Netherlands, the United States, England and Libya — from student housing in Munich and the Fortina Hotel in Malta to apartment developments with more than a thousand units in Tripoli. This international experience means we know how to meet very different architectural, climatic and regulatory requirements.

Partner of GEALAN

Over more than three decades we have worked with leading German profile systems. Today Art Yapı is the partner of GEALAN in Türkiye. Founded in 1921 in Oberkotzau, Bavaria, and part of the family-owned VEKA group since 2014, GEALAN is known for innovations such as IKD® intensive core insulation, STV® dry glass bonding and acrylcolor® co-extruded colour surfaces.
