On the right is a list of common problems people encounter with their windows and patio doors. We've provided solutions and suggestions for each. Look for the National Fenestration Ratings Council (NFRC) label on the window or patio door. This label shows the U-Value, Solar Heat Gain Coefficient, and Visible Light Transmittance values.
The amount of air leaking in and out of a building through cracks in walls, windows, and doors. A measure of the rate of air-leakage around a window or door in the presence of a specific pressure difference. The lower a window's air leakage rating, the better its airtightness. A window in which the sash is hinged at the top and opens by pivoting outward from the bottom using a crank handle. A mechanism used in single and double hung windows as a means of counterbalancing the weight of the sash during opening and closing.
Instead of a window that looks like a vinyl replacement, Okna Windows will match your original architecture with the look and feel of your original wood windows. The OKNA Precision Weld is an excellent value when making the choice to replace windows in your home. The Precision Weld offers clean, modern lines, high-quality craftsmanship, and many options to beautify your home while making it energy efficient. Since all OKNA products are custom-made, you can be sure of a perfect fit which translates to savings on time and labor during installation.
High performance operators for corrosion resistance, effortless operation, and easy adjustability. Heatseal warm edge spacer system for excellent thermal efficiency and drastic reduction in the possibility of condensation on the inside of your window. All of our windows and doors are manufactured from high quality materials and are backed by a Transferable Lifetime Limited Warranty. A progressive multi-point locking system allows for a weather-tight seal by drawing the sash firmly and securely to the master frame.

Terrible Customer Service experience: In 2020/2021 my wife and I replaced all the windows in our house with Okna windows. Overall, quite happy with them, however, we damaged one of the windows early this year while cleaning it. We accepted it was our fault and were told that we needed a service engineer to come on-site to fix the issue. Long story short, we needed TWO balance shoes replaced on the same window.

We ordered the replacement balance shoes in advance and they arrived before the tech come on-site. The service engineer replaced ONE of the balance shoes, did an assessment of the window and deemed that the work was complete - apparently not noticing the other damaged balance shoe. Bear in mind, we sent an email before the work stating that TWO balance shoes needed to be replaced AND we sent photos of the damage BEFORE the work was started. Nevertheless, the technician told my wife that the work was complete and the window was now fine and so left our home with the $150 service fee check.

When I contacted Okna to say that the work was only half completed by the service engineer, I was told that I was wrong and that the tech fixed all the issues with the window! I sent over a picture of the still-broken balance shoe in the window along with a picture of the spare replacement balance shoe that was not used (why would I have TWO replacement parts next to the window if only ONE needed replacing?) I got an email from Okna saying that if I wanted the SECOND balance shoe replaced that I would need to make ANOTHER service appointment and pay ANOTHER $150!

I responded explaining my point of view on the matter and stating that I would NOT pay for an additional service visit when the originally agreed upon work was not completed during the first visit. I got not response from Okna thereafter (this is from 4 weeks ago). Sean N Matawan

Great window manufacturer who stands behind their product. Replaced 30+ windows in the entire house and a patio door 8 years ago. Have had a few windows with failed glass and now had all replaced under warranty at no cost to us. Could not be happier with the product and the support. We live on large acreage in an area exposed to the elements. Even when it's -20 outside the windows are warm to the touch! Love them!

3/2/2022 Purchased 3 Okna sliding patio doors. Cost $9,500. Highest model - Super Deluxe Package, Elegante, triple pane. Two years later, 3 of the large glass panels started to show cloudy contamination in-between the glass. Contacted the authorized installer and Okna will provide the replacement panes, but they would not cover the installation cost of $325. Replacement was due to the poor manufacturing quality of the product and now I am stuck with the cost to replace the defective product. Contacted Okna and they refused to cover the installation cost.

Hope I don't need to replace them again in 2 years. Okna should fully stand by their products. Shame on you Okna. Update 4/5/2022. I contacted Okna again, as they requested in their response to the original review. After further discussions Onka, we agreed to a satisfactory resolution. It did however take a month of waiting to receive it. But bottom line, Onka finally did make it right.

Cheap windows! Quality does not meet industry standards! I purchased 8 windows a few years ago, had them installed and ALL THE CHEAP, PLASTIC LOCKS ON THE WINDOWS ARE NOW BROKEN SIMPLY BECAUSE THE PLASTIC CLIPS CANNOT HANDLE THE ELEMENTS! DON'T BUY THESE CHEAP WINDOWS.

Don't not make the same mistake about buying OKNA doors. The company don't stand behind there products. I got a sliding door that has misfits like when it rain the water reach the inside sliding channels. OKNA has been to my house twice and the issue not resolved. Please think twice before you buy this kind of product. Also the stuff are not professional and very rude on the phone as well as in person. Horrible company and product

We have been using OKNA windows for 7 years in our installations. We have a lot of compliments and very few complaints about OKNA windows. It is a durable, high energy efficient and attractive window. We like working with OKNA Windows and doors company, because they do not rest on their achieved success. The company constantly innovating and improving existing products as well as introducing new modern designs and more durable hardware. Thank you OKNA Windows Company for great products, that allow us to keep our customers happy and when our customers are happy, we are happy as well!

I have been dealing with Okna as a purchasing manager of a construction company for the past 5 years. Okna has the absolute worst customer service, the windows are average at best, and if you need a service call, do not even bother. There are so many other window companies out there, why someone would choose Okna is beyond me. Everyone from Beata in shipping to Dorothy in customer service constantly passes the buck. Nobody wants to take any responsibility for Okna's mishaps, which happen often. There are plenty of other window companies out there. Stay away from this horrible company.

Okna makes a great window. We had the Okna 600 series installed last year by a company in New Jersey and they really made a big difference in the winter and also during these hot days of summer. We had one small issue and it was taken care of quickly by both okna and our contractor. Additionally, they look very nice with a high end look. Im a pretty picky person and we love the windows!

We just had 5 Okna windows installed. The installer had only been gone three hours when I asked my husband to show me how to tilt the window in to clean it. The window fell off the track and when he managed to get it back, it won't close all the way down. We had to go to bed with the window open 8 inches on the bottom. What junk. You would expect your brand new expensive windows to last more that one use. Do Not Buy Okna. I am so disappointed I could cry. We replaced these windows for the express purpose of easy cleaning and low maintenance. HA, what a joke.

I was lied to and ripped off, My Okna Bay Window started to leak. I was told by a salesman (Larry) from Okna who came to my house and saw photo's. Larry and Jason of "American Windows" who also does work with Okna both told me that this leak is the same exact problem as in many window of the same model but the owner of Okna will blame the installation, he always does and he did.

My warranty was accepted but Okna (Voytek - Owner of Okna coerced me to pay $1000 in advance. I took him to court to get my money back. The next day, Voytek (Okna) filed a claim in court for the more then I paid for the original window, He lied in court. I paid $4500 for the 1st window, $1000 for a "free lifetime warranty" and now Okna is suing me for another $4800.00.

There was no communication. If Okna had intentions to rip me off, It was never mentioned me having to pay "full price for another window". If I knew this, I would have just bought a window from a reputable Company. STAY AWAY FROM OKNA WINDOWS. It's a company that is dishonest, lies, no documentation sent. I was treated with no responses or requests from Okna.

This was the worst unreliable, dishonest, expensive experience that is ongoing after 8 months. Okna has the wrong address listed on this site. Find a reputable window company that is honest and backs there products. Don't go through what they put me through. It's not over yet!
