Window Comments

Impervia line is fiberglass. They look good overall. The hardware I got was standard white, and I have noticed it does scratch easily. I looked at the satin nickel hardware option, but it was significantly more in price. Also, the double-hung windows are a little difficult to close at the top, especially on the windows which are higher up on the wall. Shorter people would probably need a stepstool to be able to close the window completely without at least a little bit of a struggle.

I was surprised to find that an old style strings / springs balance system was used on this window. I do not like the exclusions on the warranty.

They did not thoroughly clean up after themselves. Bad caulking job - otherwise the windows are in.

Price Information

I admit I have buyers remorse. I feel like I should have bought vinyl windows with a much better warranty. I shopped Sears, Home Depot and BJ's wholesale who had vinyl windows.

I was not aware that you have to PAINT fiberglass!!! I figured it would be a maintenance free product without the expansion and contraction issues of vinyl....but just like a boat, fiberglass degrades in UV and I have to maintain these windows just like my old wood ones... :( Also, these do not meet the tax credit requirement, WHICH SUCKS!!!

Window Comments

I had some vinyl windows installed before finding the fiberglass ones from Pella. I like the fiberglass for the strength and quality over the vinyl ones I have. The one thing I don't like is that the R value is not as high as I would like and that it is lower than my vinyl windows. When I put my hand up against each of the two the Pella feels colder. One addition I would like to see on that line of window is the latches that you can find on the side that allows the window to only go up so far.

Polite courteous installers. I believe they did a better installation job than the company that I received my vinyl ones from.

Price Information

I found the price of the fiberglass windows to be only slighter more than the vinyl. I had quotes from three different places and the prices were about the same.
