A trusted name in PVC-U windows and doors since 1987. Art Yapı A.Ş. has grown from a small local supplier into an internationally active manufacturer of innovative window and door systems. We operate from a state-of-the-art facility with more than 30 employees, manufacturing over 700 products a week — supplying off-site and modular construction, home improvement, new-build, hospitality and holiday-home projects in Türkiye and across more than fifteen countries worldwide.
Established in 1987, our qualified team has more than 30 years’ experience manufacturing and fitting windows and doors across more than fifteen countries.
We manufacture our own PVC-U windows and doors, giving us complete control over both the quality of our products and the price you pay.
Visit our factory to see the Art Yapı team building doors and windows, and the care we take to create bespoke products for every customer.
Every GEALAN system we manufacture combines German engineering with lasting quality — lead-free, recyclable and built to demanding standards.
The full GEALAN window range: S 9000, GEALAN-KONTUR, GEALAN-KUBUS, GEALAN-LINEAR, S 9000 NL and S 8000 — from the 74 mm to the 82.5 mm class.
The GEALAN S 9000 HST lift-and-slide terrace door opens your living space to the outdoors with large panes and low, barrier-free thresholds.
Highly insulated, security-rated GEALAN front doors built on the S 9000 and GEALAN-KONTUR platforms, with a wide choice of panels and surfaces.

Our journey began in 1987, when Art Yapı was founded and started manufacturing PVC-U windows and doors — first as a Pimapen fabricator, then with HT Troplast, and most recently under the Kömmerling brand, until 2026.
Over nearly three decades, we have gained invaluable experience, built lasting relationships, and shared many successful projects. We are sincerely grateful to everyone who has been part of that journey.
Today, we are excited to open a new chapter. Believing that it is time to set sail toward new horizons, we have chosen to join forces with a company that shares our vision, values, and long-term commitment to quality and innovation. We are proud to become part of the GEALAN family.
First and foremost, I would like to express my sincere gratitude to Ahmet Çak and Christian Kampf for their trust, guidance, and professionalism throughout this process. From our very first meetings, it became clear that this partnership was built on mutual respect, transparency, and a shared vision for the future.
I would also like to thank the entire GEALAN team. We have been truly impressed by their passion, dedication, and the strong values they embody. It is inspiring to work with people who share the same commitment to excellence that has always guided Art Yapı.
We firmly believe that this partnership will create new opportunities, strengthen both companies, and lead to many successful projects in the years ahead. Finally, I would like to extend my sincere thanks to Ivica Maurović for his confidence, leadership, and support in making this partnership possible.
Here’s to fair winds, new horizons, and a successful journey together.
