Okna Window Costs
Explore Okna window costs on all of their most popular models such as their 400, 500 and 800 series and get suggested installed prices. The company is one of the leaders in terms of their vinyl windows. All of their window series is available in either the Delux or Energy Package - the Delux is an optional upgrade that will produce better performance numbers.
Okna 400 Window
Unlike most vinyl window companies, Okna's entry level window is a pretty solid performer, although it's not exactly cheap either. You should expect to pay anywhere from $400 to $450 per opening for the window and installation. If you opt for their Deluxe upgrade on the 400, you will get something around an AI at .05, U-value at .28 and SHGC at .30 - all very respectable numbers. The 400 is basically a stripped down, no frills version of the 500 model below.
Okna 500 Window
The Okna 500 will offer better numbers and some nice upgrades from their entry level 400 such as a better spacer system and sill wall. This translates to better perfromance numbers (AI at .02, U-value at .25, and SHGC at .28) than the 400 and one of the best value windows on the market.
Okna 800 Window
The Okna 800 is one of the top rated vinyl windows out there. Not only is the window very nice looking, it is very well built and extremely durable. Expect even better performance numbers out of the 800, especially with the DX upgrade package - U-value at .24 and AI at .01. As well as being one of the best vinyl windows out there, it is also one of the most expensive.
Okna Starmark Window Costs
The Okna Starmark is a composite window that is one of the best models available on the market. The only real knock on it is a pretty bulky frame, but consumers get a ton of durability and strength out of this window. One of the best composite buys you can make.
