Marvin Infinity Windows Reviews

Marvin Windows And Doors enjoy a strong reputation in the industry for their quality products. They are certainly a brand that I recognize for those consumers who can afford these higher priced units.

The Marvin Infinity window is the company's higher end fiberglass window, that is widely regarded as one of the best fiberglass windows available. The performance numbers on the Infinity not overly impressive, although an upgrade to one of their better glass packages can improve the numbers substantially.

The Marvin Infinity has some very nice features to it such as a single sash locking tilt lever and a huge array of hardware colors. In terms of Marvin Infinity vs Integrity Windows, the Infinity offers more options than the Marvin Integrity, which is also a fiberglass window, although typically considered a less well built and cheaper option. The infinity offers a better looking frame, more sizing options, and better hardware than the Integrity model.

The Infinity comes with a fiberglass exterior and an interior option of either the Ultrex (fiberglass) or a wood veneer called their EverWood that resembles the look of wood, but does not require the maintenance that a real wood species does.
The Marvin Infinity gets a 4.6 out of 5 star rating.

Marvin Infinity Windows Cost

Marvin Infinity windows cost will range from $1250 to $1800 fully installed. This is certainly one of the more expensive fiberglass series on the market. What's listed is also a huge price range -- whether you pay at the top or the bottom of this range will depend on a whole host of factors: installation type, size of opening, upgrades you select, and the company that does the work.

The Marvin Infinity is comparable in price to the Milgard Ultra or Pella Impervia windows.

Marvin Infinity Window Ratings

The Marvin Infinity gets decent performance numbers, but perhaps more important is the quality of the construction. Overtime, mediocre to poor construction will lead to decreasing numbers, while better made window units will continue to offer solid performance.

With the Low-e2 window package, consumers can expect a .29 U-factor, .30 solar heat gain coefficient and a .16 UV protection.

Provia vs Marvin Windows

I have 3 quotes here in Iowa where the winters get very cold. We have some interesting windows - 2 large half round Two half round windows with double casements below them. It also includes all of the wood and trim repair, which is extensive. I only plan on living here 12 to 15 years max. Love to get your opinion.

Marvin Infinity Windows - $12.9K
ProVia Endure windows (with triple pane) - $10.2K
Window World 6000 series - $7.9K

Becks, for me the ProVia Endure is the best bang for your buck here. If you were going to be here "forever" I would say consider the Infinity option, but I still think the Endure gets the better performance overall.

Marvin Infinity vs Pella Impervia

John, we have a 1920's-era cottage on Lake Michigan that used to be an old hotel. It's not heated or air conditioned, so it's only open 6 months of the year....in other words, insulation is not really that important. The original windows were replaced in 1978 with non-brand aluminum double hungs, many of which don't open or close and parts are not available.

Because we get extreme weather and heavy storms from the lake, and because we want them to be as maintenance free as possible and last for another 45 years, we're considering replacing with fiberglass.

I've attached quotes for both the Pella Impervia and Marvin Infinity, but I'm confused about the difference in cost. I thought Marvin was supposed to be more expensive, but if I'm reading this right, Pella's quote is almost 69% higher than Marvin's. (Remove the "Shed" from the Pella quote for a more accurate apples to apples comparison.)

Can you please take a look at these two quotes and let me know if I'm missing something? I can send detail pages if necessary. Any insight or recommendation is greatly appreciated!

Thanks!

Terry, happy to take a look, but unfortunately we no longer open attachments because of a virus issue from 2021. If you can summarize the quote for me, I am more than happy to give you my honest opinion...

The Marvin Infinity is the MUCH better window over the Impervia (I'm not a fan of the Impervia to be honest)

Bids are crazy! You can never tell what you're going to get. Anyway, sum them up for me and I'll give you my take (but I doubt my take will change in this case!)

Marvin Infinity Windows Cost

Looking to replace our old double pane aluminum windows, which are 25 years old. We have limited options with only three fiberglass manufacturers near San Antonio. Recently, I received an estimate of $33,000 in cash or $36,000 for the Marvin Infinity, but this was only for the front of my house, which was quite a shock! While Window World is known for being affordable, I'm not a fan of thick vinyl. I prefer a thinner profile, similar to aluminum. Since I live in the countryside and value the view, I want to ensure they don't appear too thick or overly vinyl-like. However, my husband is not on board with Marvin prices because we still need to address the windows at the back of our house.

Genie - Homeowner - August, 2023

Website Editor's Answer

Genie, I can provide you with a list of options available near San Antonio, although I'm not entirely sure how they will work out. In my experience, vinyl tends to be thicker and cheaper, while fiberglass is thinner and more expensive. If you prioritize a thinner profile, aluminum might be the right choice for you. You could consider Don Young Windows. Another option that comes to mind is the Sunrise Restorations, which is a thinner vinyl/fiberglass blend and likely more affordable than Marvin. However, I'm not certain if there is a dealer who carries it, but it's definitely worth looking into.

Marvin Windows vs Pella

Hi John, we are looking for new install Pella fiberglass windows or Marvin. @ 16 windows. We've received a few quotes from some local installers, but find some of the quotes very confusing. Also, it's very difficult to understand if we're comparing apples to apples.

Quotes have ranged from $20K (Pella 250 series) - $31K (Marvin) pocket replacements. Read Pella 250 windows reviews here.

The installers for Pella offers 20yr warranty and the lifetime Marvin warranty for pocket replacements. We are choosing to change only 16 of our units, because of cost, but we have 26 we'd like to change.

Anyway, I saw your website and thought I ask you for help and opinion.

Thanks.

John - Homeowner - November, 2021

Website Editor's Answer

John, Pella and Marvin do tend to both be expensive. Marvin fiberglass series are nice, but that material will typically run 30% more than vinyl. I personally think high end vinyl windows are the best option from a cost / energy efficiency standpoint.

I would suggest getting one to two more bids to see if you can get a better window than the Pella 250 series for under $1000 a window. I'll send you my recommendation list.

[List Redacted -- contact me directly (John) for my good and great window option.]

Marvin Infinity Windows Cost

I just received a bid for the Infinity Ultrex in Denver, CO for $18,000 to replace 15 old 1954 windows. This totals 222 square feet argon filled dual panes, LoE3-366 rating. Would be very happy to hear your opinion on the replacement window price and quality of these. I would be happy to write up a review on your site for your assistance. If you could help me with this I would greatly appreciate it. As it is the end of the month I'd like to get back to the salesman by late tomorrow, apologies if this is an unrealistic turn-around time.

Andrew - February, 2016

Website Editor's Answer

Andrew, the Ultrex is one of the best fiberglass windows and one that should serve you well with proper installation. As far as price, this seems in line generally, although its nearly impossible for me to make this judgement since I don't know the project specifics. I would highly recommend that you get several more quotes to compare price and companies. I know that Zen Windows has a branch in Denver (they sell Soft-Lite vinyl windows), I think they sell three models and the top two are good, avoid the entry level option. Also check on Alpen, which are expensive, but very well made fiberglass windows. Milgard also makes a good fiberglass window, the Ultra model, which might be a good comparison window as well.

I'd caution to take your time and get the bids and spend a bit of time doing some good comparisons before pulling the trigger.
