Elegance and Durability
Windows are a serious investment and choosing the right product is of the utmost importance. Lower cost vinyl windows are simply not strong and over time can become soft, brittle and warp. This will compromise the structural integrity of the window; eventually causing air leaks which lead to thermal failure and glass fogging. Okna Windows are engineered using a high-grade uPVC and will maintain their efficiency and beauty for years.
Look at the many features Okna's "EnviroStar" window has to offer:
Double or Triple Pane Glass with Krypton or Argon gas fill
Consists of either two or three panes of glass and two of Okna's most advanced Low-E coatings. Provides the most outstanding U-values and thermal performance in the industry. Guaranteed to save substantial amounts of money in energy costs.
Engineered for Performance
Heavy virgin uPVC extrusions with a Multi-Chambered, Fusion-Welded frame and sash deliver nearly indestructible performance.
For added strength and durabilty, the meeting rails are reinforced with a proprietary composite material which means Okna windows will not warp or bow.
Safe for the Environment
Our high-grade virgin uPVC contains no lead or harmful plasticizers.
Foam-Filled Insulated Extrusions
Okna Window frames and sashes are foam-enhanced with High R-Density Extruded Polystyrene Insulation to maximize your home's energy efficiency and comfort.
Extra Strength Glass
Increased strength and sound reduction.
Heat Shield Low-E
Comprised of 11 optically tuned layers, providing optimal climate control, neutral aesthectics and plenty of natural light. Our Low-E is a metallic coating containing silver,platinum,and titanium that is applied to the interior pane of glass to block the heat and UV rays in the summer but in the winter it prevents the heat from inside your home from escaping. This allows you to feel much more comfortable while significantly lowering your energy costs.
Heatseal Spacer
Metal spacers in other window systems act as thermal conductors-allowing heat to escape in the winter, and heat to enter during the summer. Okna's Heatseal does not contain any metal and therefore conducts no thermal energy. Heatseal expands and contracts simultaneously in response to temperature changes-eliminating sheer stress, which can cause seal failure in conventional windows with metal spacers. Okna's Heatseal Spacer offers one of the lowest U-factors in the nation.
Bulb Gasket Seal with Dual Weather Stripping
The Bulb Gasket Seal improves thermal performance, lowers drafts and provides better acoustic insulation. Dual weather-stripping eliminates drafts and air infiltration.
