oberon,

Thank you so much for your input.

As to reputations and warranties, I've heard nothing but good things about Andersen but haven't heard much, good or bad, about Jeld-Wen. (I'm concentrating on these two brands right now because they are the front runners)

As to vinyl versus aluminum, we will probably go with a cream colored exterior, so the material used for the exterior really comes down to which is a better choice for our climate. I've heard that vinyl may have problems with the expansion and contraction due the temperature variations in our area, but, again, everyone seems to have a different opinion, so I'm not sure what to believe.

Thank you for all your other other comments. They are very helpful. I'll be sure to ask about/research U-values versus R-values for the windows and ensure LowE2 glass is used.

You've gotten me started down the right path. I'll be meeting with some window reps this week. Again, thanks so much for the pointers. Windows are such an important decision! As a novice, it's hard to know how to evaluate our options. Your advice is very helpful.

You are welcome.

Again, if you have questions following your visits with the window reps, feel free to ask.

I can't stress Oberons last remarks on installation. This is honestly the biggest problem in the industry today. Make sure your window installers are certified or properly trained to install the windows you purchase. If you have them installed by people who don't know what they're doing, you'll regret it later when issues start popping up. Good Luck!!!

Since solid-fiberglass frames are the best in terms of energy efficiency I would definitely consider those. The efficiency of the framing is really important, especially since wood in frames moves in response to humidity changes whereas fiberglass does not. So, with a fiberglass frame you have superior energy efficiency.

I've been reading on this forum and others about the importance of good installation. While that makes sense, how does one go about assuring that installation is correct? In other words, I don't know how to install windows so I couldn't spot a poor installation. Is the thought if you hire a GC your hope is he has good subs?

jaymielo, I've had Jeld-Wen aluminum clad double hung windows for 12 years. I've had 2 minor problems. I selected removeable inside grills for easier cleaning. They are very fragile and break easily. Most have been replaced over the years. Also, the outside grills are sealed with a material that has discolored over the years in our Louisiana humidity. Other than that, they are beautiful and remain well sealed and energy efficient.
I'm also selecting windows for a new home. I need pairs of casements that are 7'x3'. Does anyone know of a manufacturer that can provide wood/clad casements that open in? Does anyone posting have advice on the use of butted- glass or channel glass to form window walls?
Thank you.

jeld-wens aluminum is far superior to andersens painted wood sash and vinyl frame windows, jeld-wens warranty is also superior.

andersen is a great marketing company but the window itself is not great

never buy removable grilles, they will always break, everyones do, jeld-wen actually changed to a full surround wood grille which is much better than it used to be

For what it's worth, Jeld Wen windows are of very poor, substandard quality. I have lived in many different homes over my lifetime. My current home has Jeld Wen aluminum clad windows that were installed in 2007. Living in my current home has been an absolute nightmare because of the windows. Flimsy, "cheap" quality. VERY drafty. There is just no substance to these windows. The sashes are very thin. There's absolutely no sound insulation as well. I can hear my neighbors' conversations from their yards as if they are standing in my house. Avoid Jeld Wen.
