Go Green with Enviro-Star Windows

Okna Enviro-Star Windows also called the Okna 800 Series are the most Energy Efficient windows in the industry and are specifically designed to meet the weather conditions in New Jersey. They are manufactured using a high grade virgin uPVC and are engineered so that heat is kept inside the home in winter and outside the home in summer. This reduces heating and cooling costs, minimizes energy consumption impacting the environment, and limits the size of the HVAC equipment required for keeping the home comfortable. In climates that mainly require cooling, windows have represented a major source of unwanted heat gain. In recent years, windows have undergone a technological revolution.

It is now possible to significantly reduce solar heat gain and improve comfort of your New Jersey home while providing clear views and daylight. In warm regions, this means that high-performance windows can face into the sun if desired without great energy penalties – although shading echniques remain important.

Advanced Glass Coating

Double and Triple Pane Glass


ClimaGuard™ is comprised of eleven optical tuned layers, providing optimal climate control, neutral aesthetics and plenty of natural light. These coatings consist of multiple layers of metals whose combined thickness is only 1/1000th the thickness of a human hair!

Increased Light and View

Daylight and view are two fundamental attributes of a window. Unfortunately, windows are also the source of significant solar heat gain during times when it is unwanted. Traditional solutions to reducing solar heat gain, such as tinted glazing or shades, mean that the amount of light is reduced as well. 

ClimaGuard™ with low-solar-gain (spectrally selective) coatings can provide better solar heat gain reduction than tinted glass, with a minimal loss of visible light.
This also means that views can be clearer and unobstructed.

Less Condensation with Okna Enviro-Star Windows

High-performance windows create warmer interior glass surfaces, reducing frost and condensation. Energy efficient windows with warm edge technology and insulating frames have such a warm interior surface that condensation on any interior surfaces is significantly reduced under all conditions.
