Instead of a window that looks like a vinyl replacement, Okna Windows will match your original architecture with the look and feel of your original wood windows. Their variety of windows are Double Hung, Slider Windows, Casement Windows and Bay and Bow Windows.

Sustainability

OKNA Windows spacers insulate the edge of the glass better than solid foam or metal spacers. Better insulating spacers improve the temperature of the glass, and warmer glass makes you feel more comfortable while using less energy and producing less carbon dioxide pollution. Also, their spacers improve the total U-Value for your windows, which reduces heat loss and saves money on energy bills. HeatSeal spacers can save the environment from 1,200 to 1,600lbs of CO2 per year for a typical home.
