Energy Conservation
My Pella Impervia windows were installed nearly 8 yrs. ago. I have been totally happy with them. They were installed to replace metal/aluminum windows. I live in Memphis, TN, so summers can be brutally hot here. I have an old AC system (1994); these windows have made such a difference in keeping my house cool & utility bills low. I have had none of the issues some reviewers have complained about. My windows open & shut as easily & seal as well as the day they were installed. It is amazing how quiet it is in my home when the windows are closed.
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

Not Worth Money
Rough To Open And Close
Very Cheaply Made
Best Uses
3 years ago we put in a bay window by Pella loved it, next front entry door, loved it, next, patio door loved it, I assumed what I ordered the Duraclast Impervia windows i thiught they were were vinyl, the three windows I purchased were custom made for my two bathrooms and kitchen, after my professional installation I saw how cheap they were, I could barely open any of them and when they were opened the fuzzy jams on the side of the windows started combing off from friction, I cannot believe if Pella has so many complaints from these windows why do they still keep making them, I have 6 windows left to replace and I can honestly say they are going to be Anderson, I will never ever purchase another Pella I cannot believe Pella has let their customers down on this one! They are definetly loosing their customers, with this low grade of windows! I am scared to think what is going to happen this winter! I am going to once again put plastic on my windows to keep the cold out, That was my intention when I replaced them the first time!
How long have you owned it:
One-to-three months
Bottom Line
No, I would not recommend this to a friend.

Pella Impervia - windows to AVOID!
Weather Strippinggaskets
Best Uses
Search the web and you will find additional home owners who are having big problems with Pella Impervia windows. The weather stripping / gaskets RIP when you open the windows - this is unsightly and I am trying very hard to get these repaired by Pella... I'm OVER 6 weeks into trying to work with the local Pella dealership in Bellevue WA to get the CORRECT parts ordered and installed. Super frustrating and in reading other reviews I now learn this is a common problem w/these windows. Corporate Pella Customer Service is hard to get in touch with and has yet to respond to me. Do yourself a favor and don't buy these windows. I spent over $20,000 to have them installed in my home 8 years ago and in addition to the weather stripping probems, 1 window had both springs give out (in the guest room - rarely opened window) and 2 add'l windows went off-track (also windows that are rarely opened). I chose Pella because I trusted their brand, won't make that mistake again.
