Our history in dates
2003 р

The Okna System company sells building materials. In order to expand the range of products, the company’s management decided to create a new business line – the sale of metal-plastic windows.

2006 р

During the company’s work in the window business, employees gained the necessary experience in the technical aspects of installing metal-plastic windows.
As a result, the company launched its own production of metal-plastic structures and double-glazed windows.
The company became a partner of the German concern REHAU.
Since the launch of production, we have been paying attention to the quality of our products. The requirements corresponding to the Ukrainian norms and standards set by the German partner REHAU are met.
The motto “Only high-quality windows!” has become the main attribute of the company.
As a direct proof of this, Okna System receives the status of REHAU Authorized Partner.
