replacement window design

Is it better to buy a replacement window that has mitered corners than one that has the box cut? Will it last longer? Hold up better?

Is it better to buy windows with Argon gas in them? I've heard the Argon dissipates over time. Any idea how long it takes for it to disappear?

"mitered corners" or "box cut"?

I'm assuming that you are talking about welded corners (mitered) or corners of the frame butt fit and that are held together with screws.

My prejudice is to go for the welded, or mitered corners. A corner that is mechanically held together is just one more potential leak.

Gas filled -- depends on the climate you are in. Gas works fine in really cold climates (-20 degrees or colder), but WILL eventually leak out in warm climates in the summer, where days get 95 degrees plus). Where I'm at, winter nites almost NEVER get below +20 degrees, and summer days are pretty much all above 110 to 115 degrees. Gas filled is simply a waste of money.

Low-E (or Low-E squared) glass, on the other hand is a VERY smart investment (and at times, you can get the upgrade for FREE!!) This works year 'round, simply blocking the transfer of heat. In the winter, your warm inside air isn't going outside, and in the summer, the hot outside air isn't coming in!
