Final Decision was to go with the Okna 500 Deluxe installed by a local company Aspen Home Improvements. We really like the idea of the large glass area on the sliders and they were the only company willing to quote a Bay window instead of a bow.
The installer who does final measurements came out today to do the final measurements and everything looks good. He did tell us that the reason the Bow windows are all failing was due to poor support under the bow. All of the windows have a "fog" and 1 gets sever condensation in the window.
We hope to have the installation done in early January at the latest.
Early January is really fast turn around for this time of the year and sensitivity of the weather.
