Okna 800 Vinyl Quality

Glazed-and-ConfusedFebruary 22, 2013

Do any of the experts know which companiy(ies) provides the vinyl and/or the extrusion for Okna 800 DH?

How is the Okna 800 vinyl product vis-a-vis yellowing over time?

Is the glass from Cardinal?

No, it definitely doesn't yellow or discolor over time. Okna uses a very high grade virgin uPVC extrusion with thick outer walls..you are not going to get the discoloration and warping that's common in lower quality products.
They don't use cardinal, they use guardian.

+1. The vinyl thickness and composition of the Okna product is second to none. They use Guardian glass which along with Cardinal is one of the top choices available.
