The Okna Starmark window, also known as the 900 series is always in the conversation amongst contractors and installers when it comes to the best composite windows on the market. The frame may have a some bulk to it, but you will be hard pressed to find a better made and more durable composite window.
Okna has one of the best reputations in the vinyl replacement window market, along with other top manufacturers such as Soft-Lite, Sunrise and HiMark (which are essentially Okna windows that are sold through an exclusive distribution chain that uses their own installers as a means of controlling the overall quality and reputation of its brand).
The Okna 900 composite window has a bulky frame, but does offer clean sightlines. It comes in four exterior color options and in either a white or wood laminate interior. This wood laminate does a very good job of mimicking the texture and look of real wood - go see it in person and you will see how nice it looks, without the maintenance requirements of real wood. The Starmark also offers some very nice hardware options and can be ordered as a double hung, slider, casement, awning, bay or bow.
Interestingly, Starmark window information is not available on their main website, you have to go to the Starmark site itself. The window itself comes with many of the same features and options that are available on the Okna 500 window and 800 Enviro-Star models. This includes interior colors and finishes, hardware selections and grid patterns. All in all, the Starmark window offers a lot in terms of energy efficiency, custom options, and long term value. A definite best in class vote as far as I'm concerned.

The Starmark window costs somewhere in the $65 to $75 psf price range for the window itself. Pricing should run approximately 10% o 20% more than the Okna 800 Enviro-Star. Comparable replacement windows include Renewal By Andersen Prices and Andersen 100 series costs.

The Starmark double hung window delivers impressive performance numbers. The casement window, with a low-e glass and argon fill, will provide a .18 U-value, .18 SHGC, .05 AI and .31 VT. These are very good numbers, however the air infiltration of the Starmark can't compete with the Okna 500 or Okna 800, which will come in at .02 and .01 respectively.
All in all, the Starmark 900 Series achieves very solid performance that should stand the test of time.
The Okna Starmark warranty is a lifetime warranty that covers the composite frame & sash for the homeowner's lifetime. It covers factory painted colors for a period of 10 years. The insulated glass units are covered for the homeowner's lifetime, as well as the hardware. (Hardware near the coast is only covered for a period of 10 years).
The Starmark warranty is fully transferable to another homeowner. As always, there are exclusions to the warranty that consumers should thoroughly read and understand before they purchase their windows. The installation labor costs is not covered under the terms of the warranty.

What's a fair price for 8 Starmark 900 Composite windows...3 double hung windows and 5 awning windows?? I got a quote on the Okna Starmark 900 Composite, 3 double blind and 5 shutter windows? I am being quoted $7300.

Stuart, I would probably say off the top of my head that the Starmark is going to run you $650 to $850 per window, depending on the upgrades, size of window, and difficulty of the install itself.
I think you need a few more bids. The Starmark is by far the best composite window on the market, but there are a few excellent vinyl windows that match up well. Okna 800, Sunrise Restorations, Soft-Lite Imperial LS, Soft-Lite Elements, and Polaris Ultra-Weld. If you can get a couple of bids for local dealers on these windows, they would serve as a good comparison.

I'm replacing my entire house with Starmark 900 series and a new patio door to boot. Been in my home, built in 2000, since '06 and at least 3 of the contractor grade windows have lost the inner seals as of '14 and none of them have ever had a great sealing properties ( used window kits since day 1 ) to lessen heat loss.
I'm in Iowa - there is only 1 OKNA dealer here and they have been in business for nearly 30 years. They have a good reputation. A good friend of mine introduced me to his purchase of OKNA. Prior to that I'd never heard of them. Pella and Anderson seem to be most recognized brands - but not always the most reasonably priced. A coworker is buying a replacement OKNA for his home after I spoke about the warranty, etc and he's had Pella's that have repeatedly fail. Not good for the home team ( Pella, Iowa ).
Anyway - Great Site! I looked at lot of your reviews to get an idea of where I was headed. Having a trusted friend already purchasing OKNA Starmark helped - but it's good to see other analyses and opinions.
Just an FYI - the summer sale that OKNA had ( I made it the deadline by 1 day ) was $100 off per unit. So - for me - I just applied it to triple pane and it was a wash. Overall, the cost was about $800 per unit installed with the discount. Half circle windows were about $100 more. I did the bare bones, Euro White with no additional hardware or color options or decorator options ( plain window - no hatching pattern ). Order to installation - about 6 to 8 weeks. About 1 month to go!
I'm looking forward to a quieter and more efficient home.
