Smooth Operation with EZ-Glide Technology
OKNA’s sliding windows are built for effortless function. With their signature EZ-Glide system, the sashes glide smoothly along reinforced rails — similar to a precision railway — making operation light, clean, and reliable for years to come.
Two Excellent Options – Choose What Fits Your Home
EnviroStar 800 Sliding Window
Our highest-performing sliding window, the 800 offers superior airtightness, triple-weatherstripping, and refined details like elegant handles and slim profiles. It’s the perfect combination of beauty and cutting-edge performance.

Both sliding models exceed ENERGY STAR® performance standards and are available with dual- or triple-pane glass, argon fills, and Low-E coatings. These windows not only enhance your home’s efficiency, but also modernize the look and function of any room.
