Okna 750 Windows Reviews
The Okna 750 series is the company's awning window option. Standard features include a beveled sash and frame, a nice folding crank handle, dual locks, triple weatherstripping, heatseal spacer, fiberglass mesh screen. In terms of color and hardware options, the awning is nearly identical to their 700 casement.
Consumers can choose from 8 exterior colors (including some nice dark options that include a basic brown, bronze and terra brown) and 3 interior colors - white, almond, and cocoa. Interior faux wood or laminate options include cognac, dark oak, natural, melrose cherry and winchester.
The Okna awning is available in several upgraded hardware options, including brushed nickel, matte bronze and antique brass. The Okna 750 awning window is a very nice option, well made and constructed.

Okna 750 Windows Ratings
The standard Okna 750 awning will deliver a U-factor of .24, .03 AI and an SHGC of .27 and a visible transmittance of .49. Upgrading to the Deluxe package, which includes foam-filled insulation and an upgraded low-e glass, will lower the U-factor of .19, an SHGC of .22 and a visible transmittance of .35. These are very solid numbers, comparable to the Okna 700 casement.
All of these numbers are from the nfrc.org website, which publishes performance data on thousands of window models and series from hundreds of manufacturers.
