Traditional Czech window
and door manufacturer since 1994

RI OKNA’s tradition, principles and policies

We have been developing our window and door manufacturing tradition for more than 20 years. We have refined our manufacturing processes and continue to improve them constantly. We have learned to understand our customers' needs and requirements and to satisfy them as best as we can.

Your satisfaction and long-term contacts form the basis of our work.

We hope you will be pleased with the performance of our products in the long run. To this end we listen attentively to your wishes, questions and concerns. We provide true and open information on the properties of our windows and doors. We cooperate with you to develop the architectural solution most suitable to the individual nature of your house or apartment.

Each individual product is subjected to systematic inspection so that it leaves the plant in perfect, well performing condition.

Those are the traditional performance properties of RI OKNA's products and services.


RI OKNA is a joint-stock company, established in 1994 as a facility focusing on the manufacture and installation of top-class plastic windows and doors and appropriate accessories. We augmented our production program with aluminum windows, doors, interior walls and glazed aluminum facades in 2006.

We launched one of the largest and most modern production facilities in 2008, thereby promoting our products to the very top of today’s technology potential.

We acquired majority in WD OKNA in March 2017, whereby our product range expanded to include wooden windowsr and doors.


The windows and doors comprise German SALAMANDER®brand profiles or our own RI Line® high-quality profiles and are fabricated on German ELUMATEC® machining centers.

We were among the first Czech manufacturers to launch management systems in accordance with:

  • ISO 9001 (production quality management),
  • ISO 14001 (environmental responsibility) and
  • OHSAS 18001 OHSAS 18001 (occupational health and safety management).

None of those on their own, however, are sufficient for achieving business success. It is primarily dedication and honesty in communication with our customers, as well as excellent performance in the manufacture and installation of our products that constitute the basis of our goodwill and customers' satisfaction with the end result.

n 2012 we were granted the Czech Window and Door Manufacturers Association's “CZECH WINDOWS” CERTIFICATE, confirming the Czech origin of our products and certifying that all manufacturing operations on the RI OKNA products take place in the Czech Republic.
