Why Does the Okna Insul-Tec 500 Series Window Consistently Outshine its Competition?
Vinyl windows have become the standard choice for value when looking for an energy efficient window. They are not, however, renowned for their visual appeal or extended longevity. The 500 Series by Okna proves you can make a vinyl window affordable, attractive, and built to last a lifetime.
Style is in the Details
Available in several colors, the curved and beveled colonial style framing of the 500 Series provides an upgraded, custom look not found with other vinyl windows. On the interior of the window, a fully integrated lift rail offers a clean, sleek look that blends seamlessly with any home’s aesthetic.
Customize Your Energy Efficiency
The Okna 500 Series one of the most airtight and energy efficient vinyl windows on the market today. If you are looking for additional energy efficiency, upgrading to triple pane or SunSeal Glass, or adding foam filled extrusions offers even more barriers from the outside world.
Hardware Designed to Perform
Equipped with tamper-resistant cam sash locks, the window ensures smoother operation and extends the lock’s lifespan compared to traditional alternatives. Additionally, the inclusion of spring-loaded vent latches allows for enhanced ventilation options, enabling both sashes to remain partially open simultaneously.
Optional Added Safety for Your Family
WOCD (window opening control device) locks are available as an optional upgrade. When activated, these locks allow the window to open no more than 4 inches. The device can be deactivated to open the window fully, and once the window is shut, will automatically reactivate. Optional WOCD locks can provide safety and peace of mind to families with young children.
They kept in touch with us every step of the process, we never felt like we had been forgotten. The windows came in sooner they they had quoted, and they worked with our tight schedules to get the install scheduled at a time that worked for us.

The installation process was very smooth, and the crew was professional and efficient. Overall, it was a very positive experience working with Windows on Washington, and I wish we had proceeded with the project in 2018 when we initially planned to do so.
