Ed's - with all due respect, the Okna windows are not listed in the Top Rated listings here, nor are they mentioned in the Top 100 windows on the sister site. I believe that is what Fenestra was referencing.
The top 100 was from Window & Door magazine and was based on yearly sales figures of companies that cooperated with the magazine and sent their sales info to the magazine. It is based purely on the amount of the company's sales, not how good the windows are.
The "Top 100" info from the sister site is at least 5 year old. If you look at the Top 100 in that magazine from the last several years you will see Okna on the list. The articles are available by doing a google search.
The majority of reviews in the review section of this site were put on the site right after the site added the function to do so back in the middle of the last decade. That was a few years before Okna revamped their window series, expanded west and started impressing the industry with their fantastic performance numbers and features.
We all would welcome any Okna past customers visiting here to start reviewing the Okna, HiMark and Starmark windows on that part of the site.
