Specialty Glass Options

OKNA Windows offers specialty glass in a variety of distinctive choices that add visual interest to any design while offering variability in light control. Our Regular Obscure glass for example, will be satifying to those looking for a more traditional look with obscure glass. This option is great for bathroom windows. Other available glass options are tempered, laminated, and custom configuration. With a range of options at your fingertips, you can find a standard glass texture for virtually every application and aesthetic, from traditional to modern.

ThruVision Plus is our fiberglass improved visibility screen. This product does for windows and doors what high-definition technology has done for television viewing; it improves the view by making it sharper and more vivid.
