Polaris UltraWeld Windows Reviews

Polaris windows are not much of a household name, but they make a very good vinyl window in their ThermalWeld and UltraWeld models. The company operates out of Ohio, and sells their window series through dealers across much of the eastern half of the United States.

I give Polaris Windows a 4.5 out of 5 star rating based on 18 Polaris window reviews found on our Polaris manufacturing page. This page gives links to all three series that the company sells.

The Polaris Ultraweld window is a very solid vinyl window, perhaps not in the top 5 vinyl windows available, but certainly in the second tier of top replacement vinyl windows. Standard features include all of the features on the Polaris ThermalWeld, along with a true sloped sill, internal tilt miniblinds, a sash tilt, recessed tilt latches, an extruded aluminum screen, and their energySMART low-e glass with argon fills and Intercept spacer.

The UltraWeld includes some very nice upgrades and features and absolutely gets my recommendation for a quality vinyl window that should offer nice long term value. Of course, this assumes that you get the window at a good, competitive price. Best way to do this? Get your 3 to 4 free bids from quality contractors and companies and compare!

Factors that will determine the per window cost include the size, type of window, glass upgrades, component and hardware upgrades, as well as the type of installation. Installation will run about 30% of the project total. Comparable windows include the Okna 500 Series prices and Sunrise Verde windows.

Polaris UltraWeld Ratings

Consumers can expect the Polaris UltraWeld double hung to deliver .27 U-factor, .27 SHGC and .41 VT. Most impressive is the air infiltration which can go as low as .02 with an upgraded low-e glass and krypton fills.

The solid construction and welds on this premium vinyl window means these numbers will hold up well over time. This is one reason why performance numbers can be misleading, many vinyl windows can post decent numbers on day 1, but not on day 1000. The UltraWeld is a solid contender in the vinyl window market.

Polaris UltraWeld Warranty

The Polaris UltraWeld comes with a lifetime warranty on the mainframe and sash. The warranty does not cover screen damage or glass breakage. The provision on the insulated glass unit is 30 years.

The warranty does not spell out whether or not it is transferrable to another individual, although I have read that their warranty is transferable a single time and then is good for 30 years from the date of purchase. However, I would urge all consumers to read the warranty terms and exclusions in full to verify this.

Are Polaris Windows Any Good

I have two quotes - see below. I asked about the mid range Provia Aspect window, but he said it would only be $35 less each and he said if staying in the house (I am) that Provia Endure is better.

I told him these were for new installation and I am not sure he remembered for the quote. He said he could get Provia Endure for new installation but he said it should not be hard for my contractor to do necessary carpentry on the Polaris.

I am really torn on the color right now. I need windows that will look good with the siding and just brick alone (the tricky part). The brick is very rich terracotta, especially in the sun. So nothing too light. And even a tan or beige could possibly look too stark. I think sandstone or clay would be good. And both windows have those options, though they vary.

He likes the Provia Endure but told me the Polaris is his most popular. He only sells Provia doors, says they are great. I need a new front door so it might be good if they match.

Let me know what you think of the windows and prices.

Polaris Ultraweld Series: $5315

Provia Endure Series: $4319

Website Editor's Answer

Both excellent windows to be sure! I think I'd probably go with the ProVia Endure and pocket the thousand dollars -- ProVia Endure windows are great. The Polaris UltraWeld might be a bit better, but I'm not convinced that it's worth $1K more.

Window Quotes

Polaris UltraWeld vs Vinylmax Edison Windows

Hello, I am stuck choosing between vinylmax Edison windows, or polaris ultraweld. They are both quoted at the same price. I was originally quoted with vinylmax Franklin but told installer I didn't want those as they are cheaper windows. Would you have a suggestion? My windows are mainly sliders 8 out of 10 are sliders, then 2 double hung. From what I saw the sliders performance were more similar

Brian - Homeowner - November 2020

Website Editor's Answer

Brian, the Polaris UltraWeld is the better window over the Vinylmax Edison. As proof, look at that air iniftration rating. The Polaris Ultraweld is .01, while the Edison is more like .09. The Edison is a good window, but the UltraWeld is great.

Polaris UltraWeld vs. Pella 250 Series

Tim, I have received a lot of good info from your website – Thanks! I plan to replace my old vinyl windows in my house soon. A local guy is selling the Polaris Vinyl casement replacement windows and I have never heard of them before. I saw in one of your articles you compared the Pella 250 series vs the UltraWeld a few years ago. 3 years later, do you still recommend the UltraWeld over the Pella 250 Series?

I plan to use casement (crank out) windows? I was also looking at the Anderson 100 series and Marvin windows. Curious how the UltraWeld window compares to the other brands?

The window guy I spoke with offered me 9 windows and a patio door for 5k. The others are 2-3k more...not installed.

Website Editor's Answer

Chad, the Polaris Ultraweld is an excellent window, comparable to the best on the market with its air infiltration rating. This is what the page review has to say about it.

The Polaris UltraWeld window is their top of the line vinyl window in both design and energy efficiency. The outer wall is stronger than in the ThermalWeld. It is similar to the Sunrise Restorations, but the Sunrise has a U-value of 0.28 while the UltraWeld's is 0.29, and the Sunrise AI number is 0.04 while the UltraWeld's is 0.01, which is excellent.

There are a lot of upgrades and features available, including a stainless steel spacer called the Ultracept. The casements, bays, and bows all get excellent reviews in addition to the standard.

The Pella 250 is at best a good mid range window. They aren’t even close in my estimation.

The Polaris Ultraweld is better than the Andersen 100 window and on par with say the Marvin Infinity fiberglass window. I would still prefer to have the Ultraweld over the Infinity though.

Polaris Ultraweld Casement Quote

I am replacing a very large window (114” x 56”) with casement 1/4, 1/2, 1/4. I have 2 quotes, atrium 8900 $2700 (he will do a second window same size air an additional $1500). Second quote is Polaris ultraweld casement for $1900. What are your thoughts on quality and pricing.

June - Homeowner - July, 2018

Website Editor's Answer

June, I can't exactly speak to pricing because I don't know how complicated the install. What I can say is that you have an easy choice between the two options you now have. The Polaris UltraWeld is the far better window -- and obviously much cheaper. You may want to get two more bids if you want to a lower range of price options, but the Ultraweld is a top quality window and this is clearly the option you should go with between the two.

Polaris Uniframe Warranty Question

My aunt purchased all new Uniframe windows for her porch back in 2012 from a dealer in Waterloo, Iowa. She recently passed away and in going through her papers we found a brochure for the windows and in it it states that the warranty on the windows is transferable to the new owner? I contacted the dealer and they weren't very helpful with this information. All they told me was that there was a form to fill out and you send the form and $50.00 and the warranty could be transferred. They claim they didn't have this form. Could you possibly tell me if this is the process you need to do to transfer the warranty and in fact where I could get such a form? Thank you!

Jeff - Homeowner - March, 2018

Website Editor's Answer

Jeff, I would call up Polaris headquarters and see if they are more helpful. They should be able to guide you to the online warranty and you should be able to read the 1 to 2 page document, fill out the form, pay the fee and send it back to them. I would just make sure that you get confirmation from them that they received it, etc.
