Pella Impervia Windows Cost 2026
Pella Impervia Windows Cost run in the mid to upper end range for all fiberglass windows. It isn't a favorite window amongst most contractors for the following reasons. One, they think it is unattractive in comparison to other similarly priced products such as the Marvin Integrity or Infinity fiberglass models.
Two, many feel the design and construction leave something to be desired. Three, they point out that it's performance numbers are not very impressive for the price (U-value of 0.33 in the standard double pane). The Pella Impervia does come in an array of exterior and interior colors, which is always a good thing if homeowners need to match the window frame to the existing color scheme. In addition, the window does have a thinner frame design than many of the top vinyl window options out there. Read all of our Pella Impervia reviews.
While Pella windows are a well known brand, the Impervia model doesn't seem to be a strong competitor for the price. Many installers would suggest going with the Marvin option or one of the top of the line vinyl manufacturers such as Amerimax (which also has lots of color options), Sunrise (which has a nice thin frame) or Okna.

Pella Impervia vs Alpen Zenith
| Window Series | Relative Cost | Editor Takeaway |
|---|---|---|
| Pella Impervia | About the same as Alpen Zenith | Decent fiberglass window, but often expensive for the overall quality |
| Alpen Zenith | About the same as Pella Impervia | Stronger choice if pricing and dealer quality are comparable |
"Dane, love the site - quick question for you - Pella Impervia or Alpen Zenith? Cost wise- about the same. Both local dealers and both highly rated. So all others things being equal, do i go with Pella or Alpen."

Editor's Advice:
Shay, this is an easy answer; the Alpen by a mile. The Pella Impervia is just okay, but sold at a really high price point for the quality. The Alpen Zenith is a top-tier fiberglass window that would make my top five best fiberglass windows on the market. This is a no-brainer for me.

Pella Impervia Windows Cost

| Pella Impervia | 11 windows for approximately $17,050 | High quote for insert replacement windows |
| Average Installed Cost | Approximately $1,550 per window | Expensive for this series compared with stronger alternatives |
| Installation Type | Insert replacement only | Cut-out and swap installation should usually be less expensive than full-frame work |
"I recently got a quote on the Pella Impervia. Love to get your take. The quote was for 11 windows and it came out to $1550 installed. And this was just when they cut the window out and swap it for the new one. Doesn’t it seem high to you?"

Editor's Advice:
Cheryl, $1550 for an insert window seems a little high to me. But this is on the Pella Impervia window, which is typically quite expensive. The better question is whether I think it’s worth $1550 per window. The answer to this question is no.
For $1500, I think there are a lot better options out there. I can send you a list of my favorite fiberglass windows for you to take a look. I don’t love the Impervia for a few different reasons, one of which is I just don’t think it’s a very high quality series.
I think there are better options available, but they will probably run about this same amount. But you will be getting a much better window series.
