REHAU Authorized Partner status confirmed


REHAU Authorized Partner status confirmed


In December 2021, the company “Okna System” once again confirmed the status of “Authorized Partner of REHAU. In December, our production was inspected by representatives of REHAU. The purpose of the inspection was to determine whether our company meets the high requirements that REHAU puts forward to its processors. The certificate issued to us, valid until the end of 2022, is a confirmation of the successful inspection. Despite the rather stringent requirements for obtaining this certificate, our company has been annually confirming these requirements for 10 years and will continue to do so. What is the status of an Authorized Partner?
