Okna 500 Windows Reviews
The Okna 500 window, also known as the Insul-Tec Series is the mid range vinyl window option from Okna and can be ordered as a double hung, single hung, picture, slider, or hopper window. It is also available as a replacement or in a new construction set up. The Okna Insul-Tec window is one of my top selections for best long term value window.
The 500 offers several improvements over the entry level Okna 400 window, including an improved sill wall, spacer and several additional features and upgrades. The result is a better looking and performing window from the 400 model.
Standard features include a 3¾" depth mainframe, beveled colonial frame, optional auto-lock, Heatseal spacer , full integral interlock, fiberglass mesh half screen, double weather-stripping, and fully extruded sash handles.
The 500 model can be ordered in an interior white, almond or cocoa. On the exterior, it comes in white, brown, bronze, cocoa, sandstone, almond, as well as a number of additional custom colors. Hardware comes in the three interior frame colors.

Reliabilt 3900 vs Okna Insultec
After many weeks of researching replacent vinyl windows, I've narrowed my choices to the Okna 500 Insul-Tec series, Reliabilit 3500 series and 3900 series. We're replacing 19 windows. The Okna and Reliabilt 3900's are only $400 apart. However the 3500's are 3K less.

Mark, I would say go with Okna Insultec, it's probably my number one pick for best valued vinyl window out there. Reliabilt windows are the best of the "retail windows" - i.e. windows that consumers can buy off the shelf at HD or Lowes, but I've never heard any contractor claim that Reliabilt is a first tier window manufacturer (Reliabilt doesn't even make their own windows, they are simply a relabeled Atrium window.)
Unless the $3K is just too good to pass up, I'd say the Okna is the clear winner.
