OKNA's are in. Got OKNA 800 series.
U factor is 25.
Large bay in front looks great.
All operate as expected. Got full screens so I can open tops
to let hot air out.
Will update in a week or so after use.

Performance numbers are virtually the same. The DH800 is designed to look like a wood window (similar to the Starmark) with the metal lift handles. It has slightly better air infiltration numbers than the Starmark and a more friendly tilt in sash mechanism than the Starmark.

okna is getting a total u factor of .15. however, most of my customers choose argon gas due to krypton being very expensive.
