+1 to Anthony. The 500 is an excellent window and is slightly less expensive. The 800 really is the cream of the crop.

So I went to check out the NFRC website under under Okna 800 they have about 30 variations listed by a CPD number. What's that?

There are multiple variants of glass and option packages.

The Okna 800 Deluxe with double pane with grids would be this model: http://search.nfrc.org/search/cpd/cpd_search_detail.aspx?cpdnum=OKW-K-23-00018-00002

There is no NFRC data for the Okna 800 with Laminated glass.
