I'm replacing one double hung window in our bathroom as part of the bathroom remodel. I have about 25 original double hung windows in a home built in 1913 with all natural Douglas fir trim/moldings. So whatever I chose in the bathroom I will need to match up in the rest of the home. I do not want cheap white Vinyl windows. I've done a little bit of research and called Marvin directly to figure out the difference between the three Marvin Windows they make: The Ultimate, The Integrity, and The Infinity. You actually have to talk to three different departments to find out more about each window. What I found out is that the Ultimate and Infinity are very similar looking and would match up nice in an older or even historical home. The Integrity is more modern looking and that's the only big negative for my situation. If I had a newer style home instead of a Victorian Colonial I would opt for a casement window because they seal air tight when closed unlike the double hung, but it would look awful. So the Integrity is out of the equation for me. I found a reputable installer on Angie's List so I agreed to purchase an Infinity window which is 100% fiberglass with the Ever-wood interior option, and rain glass on the bottom sash. I can even stain the interior with a gel type stain to match the existing wood trim. I think it's a great idea to use an all fiberglass window in a bathroom because of moisture and humidity concerns, and to go one step further maybe opt for the triple pane in just the bathroom. Eventually the pine wood will rot away in the bathroom, and condensation will build up on the inside of the glass from showering. Pine is never recommended on exterior trim because it rots out quickly, they recommend Cedar or Douglas fir usually. Recently I used a white PVC vinyl trim that I will never need to paint on the outside made by Aztek from a local lumber yard. I think this would also be a great choice for interior trim inside a bathroom by the way. I've tried the best white exterior paints added the mold inhibitor additives and the paint eventually cracks after a few years. The other option if you want natural wood is to go with a nice hardwood, like oak, cherry, mahogany, or maple and use a clear Benjamin Moore stain, just don't use pine in the bathroom. If I'm happy with the one Infinity in the bathroom I could have all the windows upstairs replaced with Infinity ones. I will opt for the grills only on the windows located on the front of the house. Maybe go with the Marvin Ultimate with stone white Aluminum clad exterior Doug Fir on all the downstairs windows. My house has vinyl siding with storm windows and shutters. The Infinity Installer said they will need to remove the stormers or it will void the Marvin Warranty (which is excellent by the way 10yrs+ I believe) and they will have to use aluminum to wrap the outside trim. There's a little more to replacing the window than I thought. I will update with pictures after the install.

I put in 12 Infinity full replacements in my circa 1954 house last summer. I think they are very good windows. But the installation was a nightmare. Make sure you have an installer you can trust or you'll be sorry. The only gripe I would have about the windows is this: I wish I had known enough about how the finished window would appear to have had them sized and framed inward about an inch more all around thus necessitating a wider jam extension. They would just look a little more substantial. I chose full replacements because of large gaps around the old window jams/frames that inserts would not have rectified and thus energy efficiency would have been sacrificed. As it is they look great but appear a little less substantial compared to how the original windows looked. It's amazing how quiet the house is now. One other nit pick is that they have full screens and when it rains you can't see out until the water dissipates from the mesh. I would ask to visit someone who has had the windows your considering installed in their home in the last few years. Marvin is a good product for the money but I cannot emphasize enough.... you have to find a skilled trustworthy installer.... Good Luck!

It gets very cold in MN. Like I said, I had the Marvin Integrity - which was fiberglass exterior/wood interior and really liked the casement version. The Marvin Infinity is fiberglass exterior and interior. I did not want wood interiors because I don't want to worry about painting/repainting or wood being exposed to or damaged by potential condensation. Both windows have the same argon gas and low E366 glass. I know the Lindsay is a good window, but I did like the look of the Marvin Infinity better, did not care for the look of the corner welds on the Lindsays vinyl. I feel that the increased strength of fiberglass over vinyl is worth the extra $4000. This is not a DIY project. The windows will be installed by a contractor that is an authorized installer of Lindsay and Marvin with 66 years in business.

Since we live in the Denver area we were looking at fiberglass because it is supposedly hail proof (we are tired of disrupting our lives for home/auto hail damage). We have Milgard vinyl in our current home (original builder grade from 2006) and they are junk...parts breaking, windows hard to operate, etc. so we wanted something in our new home that would that give use better longevity. Furthermore, it seems like fiberglass models give you more window and less frame which is appealing because we want as much light as possible. Finally, it seems like wood windows are a maintenance issue...fading We plan on getting bids from Milgard (hopefully their is a big difference from their builder grade product) and maybe Pella. We also have a 2nd Marvin Infinity dealer in town but their reviews are not that great. Other suggestions on a quality fiberglass option would be appreciated but it seems like there are fewer options.
