Enviro-Star 800 Series - Maintenance Free Never Looked so Good
Imagine the energy efficiency of a modern vinyl window with the traditional, elegant look of a wood window. Okna’s 800 Series delivers classic beauty along with industry leading performance and quality.
Timeless Design
Everything about the 800 Series is inspired by the traditional wood window, from the beveled profile to the use of handles instead of lift rails typically seen in most vinyl windows. The 800 Series can also be painted to match any exterior, further providing a custom, upgraded look.
Clean Up is A Breeze
Adding to the classic look of the 800 Series is a recessed vent and tilt latch that mimics a real wood window. This design is a hallmark of Okna’s 800 series that not only adds to its visual appeal, but also makes tilting the windows inward for cleaning easier than ever.
Designed to Perform, and Last
A one-piece sloped seal allows for proper water drainage, while the sill dam wall is mortised into the jamb, thus adding strength and minimizing leaks that may occur at corner seals. In addition, dual weather stripping is also in place to minimize drafts and air infiltration. Every detail of the 800 Series has been meticulously crafted with beauty, longevity, and energy efficiency in mind.
Strength Behind the Beauty
Design Pressure is a rating used to measure a window’s ability to withstand wind and other elements while maintaining structural performance. The 800 Series innovative design provides maximum glass space with a Design Pressure rating that is 99% better than the industry minimum! With the addition of high density composite reinforcement inside the upper sash, the 800 Series is one of the most structurally sound windows on the market.
